The Basics

There are so many types of jewelry available today, and the variety of shapes, sizes, colors, materials, and finishesseems endless. One might think that they all require specialized care. However, there are simple measures you can taketo preserve your pieces. Limit exposure to the following factors.

Lotions & Potions

Through our daily grooming rituals, we're exposed to various chemicals that may not harm us but could beharmful to our jewelry. Commonly found in hairspray, mousse, body lotion, moisturizer, perfume, makeup,shaving cream, and soap, they can leave behind a residue and create a dull film that's difficult to remove. Toprevent buildup, remove all jewelry before bathing and grooming.

Household Chores

Take off all jewelry before performing any kind of household chore or project. Harsh, abrasive cleaners andchlorine can cause hard-to-remove buildup and dull scratches. Also remove jewelry when working with powertools. Chains, rings, and earrings can easily get caught, resulting in serious injury. Follow all instructions whenusing such tools.

Water

Although we use water to clean much of our jewelry, you should thoroughly dry your pieces after exposure towater, especially before storing in an enclosed space. Moisture fosters tarnish on silver and can weaken springsand clasps. Certain costume/fashion jewelry and gemstones should never be soaked in water or worn whenbathing (see Special Cleaning).

Extreme Temperatures

It's best to keep jewelry away from extreme heat or cold. For example, extreme heat (comparable to thetemperature of boiling water or very hot tap water) can alter the cement commonly used with cultured pearls,marcasite, or in costume jewelry. A rapid increase in temperature can cause thermal shock and lead to fractures insome gemstones or discoloration of metal. In the case of gold-bonded or gold-plated jewelry, it's best to avoidabrasive polishing materials as well as a jeweler's polishing wheel or torch.

Storage

Page 39: Gemstone treatments that QVC knowingly accepts · Gemstone treatments that QVC knowingly accepts. ... gemstone treatments that QVC knowingly accepts. ... chemicals, abrasives,

Give It Some Space

When storing your jewelry, place each piece in its own container or compartment. Metal can scratch or scuff othermetals. Diamonds and other hard gemstones that come in contact with metal (or even each other) can destroyluster or cause serious damage. Or, if you prefer using a jewelry box, place each individual piece in a pouch orself-sealing plastic bag. If you do use a plastic bag, ensure jewelry is completely dry before storing.

Fasten Clasps

For bracelets and necklaces, always fasten the clasp when storing to help prevent tangling.

Dry It Out

It's important — especially for silver items — to thoroughly dry jewelry before placing in an enclosed space.Moisture fosters tarnish and can weaken springs and clasps. Certain gemstones are also prone to water damage.

Cleaning

Follow these simple instructions for cleaning the following types of jewelry: carat gold, sterling silver, platinum, steel,gold-bonded, gold-plated, stainless steel, Diamonique® simulated gemstones, and most gemstones.

You'll need: A clean bowl Lukewarm water Mild dishwashing liquid or a mild jewelry-cleaning solution Fine mesh plastic or stainless steel strainer (for items with gemstones) Soft, clean, and dry cloth (dust or dirt on the cloth may cause scratches) Small and soft-bristle toothbrush or brush Toothpick

For older items with gemstones, check the settings to ensure stones are secure. Dirt and residue can act much likecement, keeping the stone in place even if the setting has become weak from wear. If this is the case, and the residue isremoved during cleaning, the loose stone may fall out. If working over or near a sink, plug the drain.

If using a mild jewelry-cleaning solution, pour it into a clean bowl. You can also make your own solution by combininglukewarm water and mild dishwashing liquid (2 Tbsp. dishwashing liquid to 1 quart water).

Place jewelry with gemstones in a strainer. Position strainer on top of the bowl and pour in enough solution so that itcompletely surrounds the jewelry. For items without gemstones, place them in a bowl with cleaning solution.

Soak jewelry for 10 – 20 minutes to soften and loosen any residue or dirt. For items with gemstones, place the straineron a large towel and inspect jewelry to make sure that all gemstones are in place. Thoroughly, but gently, brush the top,sides, and bottom of the piece with a soft brush to remove the softened residue. Make sure to brush the underside ofgemstones. Use a toothpick to reach tiny crevices. Rinse with clean water. Thoroughly dry with a cloth. Leave jewelryon a towel for an extended period of time to ensure that it's completely dry. If any residue remains, repeat the steps.

A Note About Commercial Jewelry Cleaners

Always follow the instructions when using a commercial jewelry cleaner. You can maintain its freshness by storing in atightly sealed container. A stale or contaminated cleaner may be ineffective or even damage your jewelry. Also, check

for an expiration date.
