Price of Diamonds

D iamonds have been a favourite of kings and queens for thousands of

years. Once considerably rare now they are much more plentiful due to im-proved methods of sourcing and extrac-tion.

The Price of Diamonds website is a compre-hensive up to date information and news about all aspects of diamonds from technical infor-mation right through to how to clean your dia-monds, where to buy them and what to look for in a diamond to even how to sell your dia-monds. Much information can be found in All

About Diamonds part one as well as parts two and three and they give a general grounding in diamonds, what they are and how to buy them.

The cost of buying diamonds can vary consid-erably.

Price of Diamonds

The price of diamonds, or Diamond Price, is dependent upon a number of factors. Desire, rarity and even careful clever advertising and promotion are obvious but for many people perhaps less well know are The 4 C's of Dia-monds. These give the most important factors about diamonds. These are the Cut, Color, Clarity and weight.

Diamond Cut

This describes the shape of the diamond. There are basically eight cuts of diamond. Round Brilliant Emerald Cut Princess Cut Heart Cut Oval Cut Marquise Cut Pear Cut Round Bril-liant.

Diamond Color

The second is the Color. Color of diamonds are graded into 13 colors or tints.

Diamond Clarity

Clarity is the next method of grading diamonds and describes the quality of the diamond as regards any imperfections it may have.

Carat Weight

http://www.jamesallen.com/?a_aid=4d245c7c915f2


Price of Diamonds

The last grading is carat weight. The Carat or Diamond Weight is perhaps the most important way of valuing them. Diamonds are weighed in carats and there is usually a relationship be-tween the carat weight and the cut of a dia-mond.

Buy Loose Diamonds

Loose diamonds are probably the best ones to buy as you can easily ensure you are getting what you paid for. The best place to buy loose diamonds is featured in this section. Best Place to Buy Loose Diamonds and here describes the best way to Purchasing Loose Diamonds. Buy-ing diamonds this way can save a lot of money.

Conflict Diamonds

Conflict diamonds are very much in the news and measures such as the Kimberley Process Certification Scheme are now in place to en-sure that future diamonds purchases are not conflict or blood diamonds.

One Carat Diamond

Here we explain all about the one carat dia-mond, probably one of the most popular dia-monds available. Also there is information about the one carat loose diamond which is likely to be the best way of buying a diamond.

DeBeers Diamonds

Just about everyone knows about DeBeers. This section explains who DeBeers is and how they came about. Plus it enlightens and dispels some myths about DeBeers as well.

Diamond Auctions

One of the best ways of buying diamonds is through an auction. But there are some im-portant points to keep in mind when buying

diamonds from an auction. Here we explain why

Black Diamonds

Black Diamonds are very rare and it takes a lot of effort to find them. But for some people it is well worth the effort. Information on theBlack Diamond Price is well worth having also.

Antique Diamond Ring

Auctions are a good place to buy antique dia-mond rings. You can get a good diamond price for some very valuable rings this way.

Diamond Substitutes

Diamond substitutes, such as cubic zirconia, are more affordable if the budget is an issue but you still want something nice and spectac-ular.

Cultured Diamonds

Cultured Diamonds, however, are entirely dif-ferent. These are real diamonds grown in a la-boratory under great pressure. The are ex-pected to replace the expensive diamonds just as cultured pearls replaced the natural some years ago.

Having been engaged rather a lot of times, Zsa Zsa Gabor was asked whether a lady should give back the ring. Her answer?

"Of course dahlink, but first, you take out all the diamonds.” ― Zsa Zsa Gabor

Diamonds are only lumps of coal that stuck at it no matter how much heat or pressure

they faced.” ― Jeffrey Fry

“It [Bach's cello suites] is like a great diamond," said [Mischa] Maisky in a thick Rus-sian accent, "with so many different cuts that reflect light in so many different ways.”

insured for its replacement value and not the market value. The difference can be enormous.

Diamond Appraisal

Some people ask, What is Diamond Appraisal?

Getting your diamond properly appraised is vital to ensure you know that you have pur-chased what you expected and paid for. There is a big section on Diamond Appraisal.

Cost of Wholesale Diamonds

One would expect the Price of Wholesale Dia-monds to be a lot cheaper than retail. Well that depends on a number of factors and here you can find out what they are.

How to Sell Diamonds

Selling diamonds can be a bit of a shock for

some people when they discover that they are not going to get what they expected. So know-ing How to Sell Your Diamond and How do I Best Sell My Vintage Diamonds is important. Sometimes it is better to Sell Loose Diamonds than selling diamonds in their settings.

What is a Pearl?

A pearl is a hard, rounded object produced by certain animals, primarily molluscs

such as oysters. Pearls can be used in jewellery and also crushed in cosmetics or paint formu-lations. The pearl is highly valued as a gem-stone and is cultivated or harvested mostly for jewellery. Pearls are formed inside the shell of certain bivalve molluscs. As a response to an irritant inside its shell, the mollusc will deposit layers of calcium carbonate (CaCO3) in the form of the minerals aragonite or calcite (both crystal-line forms of calcium carbonate) held together by an organic horn-like compound called con-chiolin. This combination of calcium carbonate and conchiolin is called nacre, or as most know it, mother-of-pearl. The commonly held belief that a grain of sand acts as the irritant is in fact rarely the case. Typical stimuli include organic material, parasites, or even damage that displaces mantle tissue to another part of

the animal's body. These small particles or or-ganisms enter the animal when the shell valves are open for feeding or respiration. In cultured pearls, the irritant is typically a cut piece of the mantle epithelium, together with processed shell beads, the combination of which the ani-mal accepts into its body. The unique lustre of pearls depends upon the reflection and refraction of light from the translucent layers and is finer in proportion as the layers become thinner and more numerous. The iridescence that some pearls display is caused by the overlapping of successive layers, which breaks up light falling on the surface. Pearls are usually white, sometimes with a creamy or pinkish tinge, but may be tinted with yellow, green, blue, brown, purple, or black. Black pearls, frequently referred to as Black Tahitian Pearls, are highly valued be-cause of their rarity; the culturing process for them dictates a smaller volume output and can never be mass produced. This is due to bad health and/or non-survival of the process, re-jection of the nucleus (the small object such as a tiny fish, grain of sand or crab that slips natu-rally inside an oyster's shell or inserted by a human), and their sensitivity to changing cli-matic and ocean conditions. Before the days of cultured pearls, black pearls were rare and highly valued for the simple rea-son that white pearl oysters rarely produced natural black pearls, and black pearl oysters rarely produced any natural pearls at all. Since pearl culture technology, the black pearl oyster found in Tahiti and many other Pacific Island areas has been extensively used for producing cultured pearls. The rarity of the black cultured pearl is now a "comparative" issue. The black cultured pearl is rare when compared to Chi-nese freshwater cultured pearls and Japanese and Chinese Akoya cultured pearls, and is more valuable than these pearls. However, it is more abundant than the south sea pearl, which is more valuable than the black cultured pearl.


Price of Diamonds

This is simply due to the fact that the black pearl oyster Pinctada Margaritifera is far more abundant than the elusive, rare, and larger south sea pearl oyster - Pinctada Maxima, which cannot be found in lagoons, but which must be dived for in a rare number of deep ocean habitats. Black cultured pearls from the black pearl oys-ter - pinctada margaritifera - are NOT south sea pearls, although they are often mistakenly described as black south sea pearls. In the ab-sence of an official definition for the pearl from the black oyster, these pearls are usually referred to as "black Tahitian pearls" The cor-rect definition of a south sea pearl - as de-scribed by CIBJO and the GIA - is a pearl pro-duced by the pinctada maxima pearl oyster. South sea pearls are the colour of their host pinctada maxima oyster - and can be white, silver, pink, gold, cream, and any combination of these basic colors, including overtones of the various colors of the rainbow displayed in the pearl nacre of the oyster body itself. The largest pearl ever found so far, came from the Philippines in 1934. It weighed 14 lbs (6.36 kgs) when it was discovered by an anonymous Muslim Filipino diver off the island of Pala-wan. Later, a Palawan chieftain gave the pearl to Wilbur Dowell Cobb in 1936 as gift for hav-ing saved the life of his son. It was first called the Pearl of Allah and is now officially named the Pearl of Lao-Tzu. Natural pearls are 100% nacre. It is thought that natural pearls form under a set of acci-dental conditions when a microscopic intruder or grain of sand enters an oyster (mollusc) and settles inside the shell. The oyster, being irri-tated by the intruder, secretes the pearl sub-stance called nacre to cover the irritant. This process is repeated for many years, thus pro-ducing a pearl.

'Cultured' pearls (nucleated and non-nucleated or tissue nucleated cultured pearls) and imita-tion pearls can be distinguished from natural pearls by X-ray examination. Nucleated cul-tured pearls are often 'pre-formed' as they tend to follow the shape of the implanted shell bead nucleus. Once the pre-formed beads are insert-ed into the oyster, it secretes a few layers of nacre around the outside surface of the implant before it is removed after six months or more. When a nucleated cultured pearl is X-rayed it will reveal a different structure to that of a nat-ural pearl. It exhibits a solid center with no concentric growth rings, compared to a solid center with growth rings. A natural pearl how-ever is solid nacre or 100% pearl. Also it is an all-natural shape, round being the rarest for-mation. So basically, what makes a pearl a pearl? They must have an outer nacre (mostly arago-nite) layer to be considered true pearl so only pearls from molluscs with a nacreous mother of pearl lining are considered "true" pearls. How Pearls are Grown Oysters are raised in a tank, allowed to attach to fibers, then grown in sea water for two to three years. Growing oysters are suspended in cages hung from rafts. They feed on plankton. Healthy oysters are selected for pearl cultiva-tion. The bead is prepared. Mikimoto use Pig toe clam shells, from the Mississippi River. Small balls are prepared from pieces of these shells. An example of a mother of pearl bead. Living oysters are wedged open and a piece of mantle lobe harvested from another oyster, plus a bead, are inserted into the soft tissue. This image shows insertion of mantle tissue and bead. Here is a labelled version of this im-age, showing the important components. Oysters are then returned to the sea, where they are suspended in cages 7 - 10 feet below the surface. They are maintained and harvested


Price of Diamonds

after some time. The culture period used to be ~ 3.5 yrs., producing ~ 1mm layer on the bead, but now the culture period may take less than 2 yrs. The commercial production method is now known as the Mise-Nishikawa method. Typical results show that 5% are high quality pearls (hanadama), 28% are not high quality but are marketable pearls, 17% are unmarketa-ble pearls, 5% are uncoated nuclei and 50% of oysters containing nuclei will die. The selection and presentation of pearls is by their size and color (hue). Careful color grad-ing is extremely important. Pearls are then drilled from both sides, often at a place that is slightly flawed. They are then sorted, treated, and marketed. Quality natural pearls are very rare jewels. Ac-tual value of a natural pearl is the same as oth-er "precious" gems, and depends on size, shape and quality. Previously natural pearls were found in many parts of the world. Present day natural pearling is confined mostly to seas off Bahrain. Austral-ia also has one of the world's last remaining fleets of pearl diving ships. Australian pearl divers dive for south sea pearl oysters to be used in the cultured south sea pearl industry. The catch of pearl oysters is similar to the

numbers of oysters taken during the natural pearl days. Hence significant numbers of natu-ral pearls are still found in the Australian Indi-an Ocean waters from wild oysters. X-Ray ex-amination is required to positively verify natu-ral pearls found today. The value of the pearls in jewellery is deter-mined by a combination of the lustre, color, size, lack of surface flaw and symmetry that are appropriate for the type of pearl under con-sideration. Among those attributes, lustre is the most important differentiator of pearl quality according to jewelers. All factors being equal, however, the larger the pearl the more valuable it is. Large, perfectly round pearls are rare and highly valued. Teardrop-shaped pearls are of-ten used in pendants. Irregular shaped pearls are often used in necklaces. An opera will be long enough to reach the breastbone or sternum of the wearer, and long-er still, a pearl rope is any length that falls down farther than an opera. Necklaces can also be classified as uniform, where all the pearls are the same size, graduat-ed, where the pearls are arranged in size from large in the centre to smaller at the ends, or tin cup, where pearls are generally the same size, but separated by lengths of chain.

Cash for Diamonds A Review

M any people have heard of the Cash for Gold and how it is possible to sell gold.

There are a lot of companies willing to buy your gold and you can find many of them re-viewed at Scrap Gold Dealers.

But what about selling diamonds?

One such company that will buy diamonds is Cash for Diamonds USA.

Here is some information about Cash for Dia-monds USA to help you decide if this is the way to go when selling diamonds.

A few points to bear in mind first:

1. You are not going to get the original price you paid for your diamond(s). If you paid retail you would have paid at least 50 to 300 percent more than the wholesale value of your dia-mond. The best price you can expect would be to get around 30 percent of the price you paid.

2. You should have a certificate or something that states the characteristics of the diamond before you offer it for sale. What is its carat weight?, Color Clarity and so forth. If you are

selling a fairly expensive diamond it may be well worth getting a certificate for if if you do not have one already. Do not rely upon blind faith that who ever you sell a diamond to, re-gardless of who it is, is going to necessarily make a fair and accurate estimate of the value of your diamond based upon its true character-istics.

3. It may be worth while looking at selling your diamond by auction or privately. You are likely to get more as the diamond values are increasing steadily.

4. It is important to understand how diamonds are graded. Cash for Diamonds USA grade dia-monds on the basis of the following found on their website:

a. CARAT: The stone’s weight expressed in carats where 1 carat = 0.2 gram. The price per carat doesn’t increase proportionally as size goes up. It varies with certain established carat weights. That’s why a diamond of 4 carats is more costly than four 1-carat stones of the same quality. The weight of small diamonds is expressed in ‘points’ rather than percentage of a carat. For example, a 0.4 carat diamond equals 4 points.

b. CLARITY: A diamond’s clarity can be af-fected by various types of imperfections such as cracks, small pockets, tiny bubbles or other foreign substances that are inclusions within the stone. A perfect stone is free of these.

c. CUT: The way a diamond is cut affects its ability to reflect light and its apparent bril-liance. It does this by refracting light from fac-et to facet and then by finally dispersing it out from the topmost facet of the stone. The most valuable stones generally have the greatest brilliance.

d. COLOR: White diamonds, or those without


Price of Diamonds

any colouring, are usually considered the most valuable because they permit light to be passed through and dispersed as a rainbow of colors, much like a prism does. However, if a colored diamond is bright enough, it is considered a “fancy gemstone” and may have considerable value. Pink and blue stones are most valuable.

5. In fact very few diamonds are actually col-ourless and most are at least tinged with some color however faint. Red diamonds are very rare indeed. Many diamonds have some tint of yellow as a result of small amounts of nitrogen in the stone. When brighter than average, these diamonds are referred to as “canary” stones. There are also green and black diamonds which nearly always have some white inclu-sions as imperfections in them.

6. Clarity, Cut, Color and Carat are all factors that a diamond buyer should take into account when appraising each stone they receive. The bigger the diamond the more per carat it is worth given that the color, clarity, size and cut are all of good quality.

Ok, now on with the review.

According to Norman Schneider, CEO of Cash for Diamonds USA:

“If you are not satisfied with your payment for any reason, simply notify us, then return your check within 14 days of the date printed on the check and your items will be returned to you free of charge.” -Norman Schneider, CEO

The company, actually CJ Environmental, Inc. claims a high reputation and a long history for excellence in the precious metal and diamond fields. They have their own refinery for pre-cious metals (of course they buy gold, silver and other precious metals) and have been

around since 1975.

Cash for Diamonds USA State on their website, cashfordiamond-susa.com, that they offer direct to the public rates normally reserved for brokerage firms. Whether this means they pay more or less I could not discern but the website says, “Because we process such a high volume of DIAMOND SHIPMENTS every month, we can afford to pay you top-dollar for all of your diamonds and precious metal settings. We guarantee you’ll be happy with our settlement or we’ll return your material to you.”

Cash for Diamonds USA Sends a FedEx la-bel Cash for Diamonds will send you a FedEx shipping label to ship your unwanted diamonds or other jewellery and they cover the cost of shipping and insure the package for loss or damage. Within 24 hours of receiving the package they will mail you a check.

Cash for Diamonds USA will also assay the settings They will determine the value of the gold, sil-ver or platinum based upon weight, purity and current market price, and include payment for that in your cash payout. Presumably a break-down in that situation is included.

Cash for Diamonds USA Offer satisfaction guaranteed If for any reason you are not satisfied you can contact them within ten (14) business days from the date on the check and they will return your items at no cost to you.

What Diamonds do Cash for Diamonds USA buy? Basically any item that contains diamonds. These include wedding bands set in gold, sil-ver or platinum; items that contain small dia-

monds, such as watches, belt buckles, necklac-es or rings; loose diamonds bought on their own or that may have come from custom-made jewelry; and large, sometimes specially-cut diamonds, which tend to be worth the most. You can even send in jewelry that doesn’t con-tain any diamonds at all, such as gold & silver jewelry.

What Size Diamonds Do Cash for Diamonds USA Accept? Cash for Diamonds will accept all sizes. No diamond is too big or too small. That also in-cludes broken jewellery as, of course, as long as it contains diamonds, they claim they will be able to pay you for it. The condition of the material doesn’t influence the amount of mon-ey you’re going to receive. Your compensation is actually based on the weight and purity of the materials you send in, which means that broken jewellery will appraise just as well as regular jewellery.

Diamond Glossary

H ere are some common words used in the Diamond Industry and in this newsletter.

4Cs Diamonds are graded and priced according to what is universally referred to as the "4C's". They are Cut, Color, Clarity and Carat Weight. Below an explanation of each of the 4Cs: Appraisal A valuation of property by the estimate of an authorized person. With diamonds the apprais-al is a written estimate of the approximate re-tail replacement value of diamond jewelry, which may be used for insurance coverage or other purposes. It is not the same as a grading report, which evaluates a diamond's character-istics (such as cut, clarity, carat, symmetry, etc.) only. Blemish A scratch or abrasion on the surface of a dia-mond. Provided they do not interfere with the symmetry of the stone and do not interfere with light in the stone they are not considered important. Brilliance brilliance is the white light that is reflected through the top of a diamond. This can be in-crease by the diamond being cut to the correct proportions to take advantage of the reflection of light from the facets to the brilliance. Brilliant Cut A Brilliant Cut, sometimes called the Ameri-can Brilliant, is a 58-facet round diamond,

This shape and faceting arrangement is de-signed for maximum brilliance, sparkle and beauty and is perhaps the most popular shape. Carat Perhaps everyone know the term carat. The basic unit of weight for a diamond. A carat is equal to 200 milligrams, or one-fifth of a gram. It is said that the word is derived from the word carob. In early India the carob bean was used for measuring the weight of gems as eve-ry carob seed weighs exactly the same. Clarity Clarity is the term given to indicate the purity of a diamond. Most diamonds have minute im-perfections and the clarity is the way of grad-ing the purity depending on the number of im-perfections the diamond has or does not have. Cloud A cluster of very small inclusions inside a dia-mond that give a cloud effect. Tiny clouds will not interfere with the flow of light, but large or numerous clouds can affect brilliance. Color Diamonds are traditionally thought of as white or clear. But diamonds in fact do have color and this can be graded. Crown The crown is the top section of a diamond, above its widest point, or girdle, that compris-es the table, and the star-, bezel- and upper-girdle facets. Culet A facet on the very bottom of a diamond. It is best to have a small or medium culet. A large culet will make it look like there is a hole in the bottom of the stone due to leakage of light. Absence of a culet makes the point of the dia-mond more easily damaged or chipped.


Price of Diamonds

Cut This describes the shape of the diamond. There are basically eight cuts of diamond.

Round Brilliant Emerald Cut Princess Cut Heart Cut Oval Cut Marquise Cut Pear Cut Round Brilliant

Some of the most popular diamond cuts in-clude Heart, Emerald, Marquise (Oval with pointed ends), Oval, Pear, and Princess with the Round Brilliant (R/B) probably being the most popular. Depth % (percentage) The height of a diamond (measured from the culet to the table) divided by the width of the diamond. The depth % is critical to creating brilliance and fire in a diamond. A depth % that is too low or too high will cause light to leak out of the stone, causing the diamond to lose sparkle. Depth The height of a diamond (measured from the culet at the very bottom to the large table facet on the top). Diamond The simplest of all the gemstones consisting of pure crystallized carbon. A diamond crystalliz-es under enormous pressure deep beneath the earth's surface Diamonds can be from 1 to 3 billion years old--more than two-thirds the age of the Earth itself. Diamond is also the hardest substance known to man. In fact, it can only be cut and polished by another diamond. Despite its hardness, however, it is not indestructible. If a diamond is struck at the right angle, it can chip or break.

Eye-clean A diamond that has no inclusions visible to the naked eye -- flawless to the naked eye. This is normally true of all diamonds with a grade of about SI-1 or higher on the clarity scale. Facet The polished flat surfaces on a diamond. For example, a round brilliant diamond has 58 fac-ets including the culet. Fair Cut Diamonds cut to less than perfect proportions. They have been cut to maximize the weight of the stone instead of enhancing the brilliance and sacrifice fire and brilliance. The less ex-pensive stones may have good and very good cuts but will not have the same brilliance and fire that people would expect from a diamond. Fire Fire is the colored light that is reflected from inside the diamond. Colored light reflected from within a diamond. As in a prism light en-tering a diamond is divided up into the spec-trum. The better quality diamond with better proportions the better the 'fire' of the diamond. This is called "refraction" or "dispersion" in the diamond trade. Fluorescence A glow, usually of a bluish color, which ema-nates from certain diamonds when exposed to ultraviolet light. Two thirds of all diamonds fluoresce to some degree but how they do so depends very much on the type of ultra violet light they are under. Girdle this is the narrow band around the outer cir-cumference of a diamond. This is where a jew-elry setting holds the diamond in a ring. Good Cut Diamonds cut with acceptable, but not perfect,


Price of Diamonds

proportions. They generally have very good brilliance and fire and make excellent jewelry. Ice A colloquial word for diamonds, much favored by Hollywood in movies about gangsters. Ideal Cut Ideal Cut diamonds are usually more expen-sive than all other cut grades. This is due to three major factors: 1) extra time and skill are required to cut to such precision; 2) they are in great demand, and perhaps most importantly, 3) more of the original rough diamond must be sacrificed to achieve ideal proportions. Ideal Cut diamonds are also round diamonds that are perfectly proportioned (having depth percent-ages and table percentages that some people feel produce a "perfect" balance of fire and brilliance). They almost always have the high-est grades on polish and symmetry as well, in-dicating the great care taken in the overall fashioning of the stone. These diamonds have had the finest craftsmanship to maximize the beauty of the diamond. Inclusion An impurity within a diamond, such as a spot or irregularity in the crystal structure of the stone. These can include a cloud, a fracture, another diamond inside the bigger one, liquid, etc. Inclusions can either be visible with the naked eye (usually SI-3 clarity and below) or visible only under magnification. Fewer inclu-sions means a finer clarity grade, increased rarity, and increased value. Kimberlite Kimberlite is a mica peridotite and a source of rich deposits of diamonds. The deposits occur-ring at Kimberley, South Africa were the first recognized and the source of the name. The Kimberly diamonds were originally found in decomposed kimberlite which was colored yel-low by limonite, and so was called "yellow ground." Deeper workings encountered less

altered rock, undecomposed kimberlite, which miners call "blue ground. Loupe A loupe is a small magnifying glass used to view gemstones. Usually 10x, or ten-power, magnification. The FTC requires all diamond grading be done under 10-power magnifica-tion; any flaws not detected under this magni-fication are considered to be non-existent by some dealers. Make Make describes the quality of the finish and proportions of a diamond. A good make will have proportions that maximize brilliance and fire. A poor make will decrease sparkle and fire due to the loss of light as it travels through the stone. The cutter is responsible for the make of a diamond as he is the one that cuts it to achieve the maximum brilliance and fire. Mohs Scale The Mohs scale is a table of relative hardness that ranks a mineral's strength and durability on a scale from 1 to 10, with 1 being talc and 10 being diamond. Developed over 100 years ago by Frederic Mohs. Moissanite Moissanite is silicon carbide and is manufac-tured in a laboratory. It is virtually indistin-guishable from diamonds and it takes a real expert with special equipment to be able to tell the difference. Pavilion This is the bottom half of a diamond, from the lower girdle to the culet tip at the bottom. The pavilion should be neither too deep or too shal-low otherwise light will leak out and the dia-mond will lose fire and brilliance. Peridotite Any of a group of igneous rocks having a granite like texture.


Price of Diamonds

Point A measure of diamond weight. One point equals 1/100th of a carat. A diamond that weighs 0.50 carat is said to weigh 50 points. Polish A grade given to the external finish of a stone. The polish grades are from poor to excellent. Good polish is crucial for maximum brilliance of a diamond, but it takes a trained eye to dis-tinguish between polish grades. Poor Cut Poorly cut diamonds with proportions and fin-ish that make them look relatively lifeless to the eye. Such stones are ok for industry but not for jewelry. Sparkle The 'sparkle' of a diamond is the combination of fire and brilliance. The light that reflects out of a diamond as it moves. Sometimes called "scintillation" by older dealers. Stones A word for diamonds and other precious gems. Symmetry A diamond should by symmetrical. Symmetry is the grade used to describe the uniformity of the cut of the diamond. This can range from excellent down to poor. The un-symmetrical a diamond is the poorer will be the quality of light through the stone. Table The top or large flat face of the diamond is

called the table. It should be in proportion to the rest of the diamond to gain the best fire and brilliance. Tourngat Diamonds cut to fit very strict requirements for depth percentage and table percentage. These outstanding proportions maximize fire and brilliance in the diamond. Also a region of northern Quebec. Weight the weight of a diamond is measured in car-ats.A carat is .2 grams. A gram of diamond would be a massive 5 carats. Very large in dia-mond terms although the actual diamond is physically small. Wholesale Wholesale prices are listed PER CARAT to show this price difference. For instance, a 1/2-carat round brilliant diamond of G/VS2 quality may sell for $3,600 per carat ($1,800 for the stone), whereas a 1-carat stone of the same quality would likely cost $6,300 per carat ($6,300 for the stone) because it is twice the size and more rare. Zirconia Also known as Cubic Zirconia, this is a sub-stance often used as a substitute to genuine dia-monds. It is a carborundum substance and easi-ly told from diamonds due to being heavier than diamonds.
