order at 7:35 pm. There are 20 members

and 3 guests present.


- 4 -

Guests: Toni Crotty and LaVerne Livsey

found us online after a friend suggested

they find a local lapidary club to join. Phil

Karls visited us tonight after moving back

into the area.

Minutes: Mark Montgomery moved to

accept the February minutes as printed in

the Petrograph. Jim Ewing seconded the

motion and it carried unanimously.

Program: We discussed what everyone

bought, saw or happened at the show.

Cathy Miller couldn't resist the blue opals

any longer. A couple of dealers were

clearancing out some strands of beads. A

labradorite heart also found a new home.

Jim Ewing found some old stock of deep

blue lapis that just wouldn't let him leave

without getting some.

Beth Farmer had to call 911 for an elderly

lady who was having a diabetic episode. One

of the dealers is a doctor and a nurse was

visiting the show both helped her out while

waiting for the ambulance. She was feeling

better by the time they showed up.

Cathy Miller reported that a dealer ended

up doubled over in pain the first day of the

show. Several members and dealers helped

her out and helped watch her booth while

she recovered. By the late afternoon she

was better.

Bonnie Andrade found several bracelets

and stone beads that she plans on re-

purposing into another wonderful piece of

jewelry.

Cheryl Gullak found many wonderful items

and every time she turned around

something new jumped up and caught her

attention.

Mike McBride had the winning bid for the

turquoise bolo from the live auction. He

proudly strutted around showing his first

ever bolo tie.

Ed Rigor bought some wonderful opal. Are

there more classes on the horizon?

Shirley Buschke noticed the auction case at

the shop is void of items. It must be time

to start working on next year’s items.

Oscar Langdon-Streeter showed us his

birthday gift. He beamed while describing

his large amethyst crystal structure.

Lillian Pate enjoyed working the spinning

wheel, but definitely enjoys spinning the

wheel more.

Stephen Caudill-Merida was excited about

getting a geode cracked, but the

fluorescent room really made the crystals

pop.

Someone mentioned how well the live

auction did this year bringing in $3700.

Thank you, Rita Frazier for coming and

doing a fantastic job.

Norm Hodgson says the exhibits looked

good. Other clubs put in cases this year

also. The GIA and GMD did a great job and

settled some disputes. One thing to note is

that we need more people to help pack up

late on Sunday.

Federation: The CFMS is at the Lodi

Fairgrounds from June 12 – 14, 2015. Mike

McBride has $1 off cards available along

with applications for competition and

exhibit cases. Rules are on the CFMS

website and Norm Hodgson said he would

help people with the rules if you have any

questions. At the show is a club central

section that needs representatives from

clubs to talk about our club. Anyone want to

be in the demo room for a 4 hour slot? Let

Mike know if you are interested. Sunday

morning is the editor and webmaster

breakfast. We discussed putting in a club

exhibit case. The “Golden Bear” will be at

the CFMS show. It is a 4 oz piece of gold in

the shape of a bear. If you have never seen

it in person you are missing out.

Shop: April 11th is shop cleanup day

starting at 9:00 am. If you use the shop

come help clean it up. April 12th is our Open

House starting at 10:00 am. It will be a

potluck with a swap meet and donations

sale. Didn't help during the show, come help

clean up to get shop privileges back. Beth

Farmer reports the two 12” saws need some

work. She just found a new source of oil for

about half the price. She is hopeful that it

will work in our saws. If you have any

questions put them in the box near the grit

sink.

Show: The show is over. Thank you to the

following for traveling the distant to help -

Cheryl Gullak from Canada, Chrissy Cody

from Santa Cruz and Rita Frazier from

Colorado. Cathy Miller says the auction and

the raffle went well. We sold all 300 lbs of

geodes and gave away all 150 lbs of tumbled

rock. The wrap up meeting is April 2nd at

the shop at 7:00 pm. We are looking for

ideas and to hear what worked and what

needs changing. It was suggested we set up

a website to advertise better and to

promote all shows. We have bought the

domain BayAreaGemShows for this purpose.

Membership: There are 112 current

members. Only paid members are covered

by the insurance. Don’t forget if you do not

pay your membership then your name is not

in the money drawing at the general

meeting. Be prepared to start bringing your

membership card with you to the shop.

Juniors: Nothing to report.

Education: Shirley Buschke says classes

will resume soon. Lee Daguman will be

holding a class on how to knot your bead

work.

Library: A few books that were donated

are being added to the library.

Field Trips: Peggy Lew is planning two trips

to the Clear Creek site. One will be a guided

tour from a geologist and the other one will

be a self-guided walk around the area. Jon

Christian is talking about a Point Reyes

tour.

Money Drawing: The name drawn tonight

for $105 is Isabella Bennette, but she was

not here. In April the amount goes to $110.

Guest drawing: Toni Crotty and LaVerne

Livsey.

ROCK RUMBLES

By Shirley Buschke

Wonderful show!! Thank you to all who

helped. The group worked extra hard

because we really needed more manpower in

the time of setting up and tearing down.

Those who only come to help during the

show have no idea how much work is

involved. We need physical help. Leave the

wearing of security coats to the senior

citizens who can’t work like they used to.

Few of you work on Saturday for delivery

to the Pavilion or Sunday for take down.

Help then! As I was leaving one of the

dealers said he loves the friendliness of our

members.

The winner of the raffle Jan Jones,

was thrilled with her prize. She has bought

lots of tickets in the past, too. She is the

wife of one of our dealers, Del’s Opals ,and

they are also members and two Cal State

students are glad she and many others

bought tickets. Money goes for

scholarships.

Nice to see old friends, Snooky Flowers

was here with a walker. Seems he had back

surgery recently. Also Bill Jeans and his

wife Jessie who have moved to the

Vacaville area were here. I also saw the

Churchills from Patterson. She brought a

contribution of supplies for our beaders and

I just found out they were the secret

donor of the $1000 to our club. Thank you

Nicki and Carl. Chris Cody came from

Felton and worked and worked and worked.

She helped set up, hung those banners,

skirted and then sold tickets for the raffle

with Doc and Diana . Rachel Rey saved

the day when they were having trouble

putting up the tents on Thursday. She used

her trusty I phone, and got the directions.

Our Pittsburg member, Chris PaVel-Liagon

demonstrated wire wrap for two days. She

comes by way of BART. That makes a

LONG day for her. Another member that

we haven’t seen for ages is Eloise Murata-

Rudiger. Missed Carlos Castillo at the cab

machine. He was ill.

I Loved the enthusiastic kids. On Friday.

Mike Mac McBride said while in the men’s

room one of the eleven year olds said “Gee,

I thought this was going to be boring. This

is cool.”


- 7 -

And another correspondent in the

Bennette family. Can you believe the

author, Isabelle, is ten years old? That

article she wrote for our Petrograph reads

like a professional author wrote it.

Finally the auction seemed to draw more

interest and bidding was up, more like it

used to be. Maybe it was the time change

to Saturday, Maybe the country has more

money to spend. Thanks to all who

participated by buying ordonating your

“rock” items. Don’t see anything in the case

yet. It always was a race between John

Gullak and Doc to get the first piece in.

Cheryl Gullak made her annual trip from

Canada, worked the show ( lots more than 4

hours) and is sticking around for a few more

days. And Rita Frazier, our auctioneer,

came from Colorado. Now those two are

truly devotees.

Saturday March 14 was pi day . (No

symbol on the computer). Roland Araya

took it literally and brought in a delicious

chocolate and whipped cream pie for us to

share. Won’t happen again for a zillion

years.

Val and Austin McThorn are planning on a

trip to see us in May, they are sorry they

missed our show. Hope they bring some

rain from Hawaii. She said it just keeps

raining.

Good visit with Phil Karl at our meeting.

He moved to the Brentwood area and

doesn’t get down here very often.

Don’t forget the clean up April 11. And

open house the next day Bring food for the

pot luck.

I was surprised to see Lyle Schoeff at

the shop Saturday, he bused, Barted and

bused to get to the shop. Seems he has put

his cycle in storage for the winter.

Vandalism was taking its toll.

ANNOUNCEMENTS

Castro Valley Science Festival

Demonstrators

Once again the Mineral and Gem Society

is being invited to participate in the Castro

Valley Science Festival to be held Saturday,

May 2, 2015 at the Castro Valley High

School, location 19400 Santa Maria Avenue,

Castro Valley. All the area school children

and their parents are invited. Parking is in

the school parking lot off Redwood Road.

For the past 3 years a few of our

members have participated in this Science

Festival, displaying their own rock

collections. A lot of interest was shown in

the items we brought. It is an enjoyable 4

hours. There is much interest shown in the

display set up by the members of the

Mineral and Gem Society of Castro Valley.

The Castro Valley Science Festival runs

from 10 am to 2 pm (set-up up time starts

at 8:30 a.m.). The Festival has exhibits,

presentations, and activities for students al

all levels (elementary, middle, and high

school). It is a completely free event.

Our display tables are located inside the

basketball gym. It's rather a long walk to

carry rocks, so hopefully you'll have a cart

to pull. Label the rocks you bring, whether


- 8 -

it be rough rock, or finished cabochons.

Lables are helpful. Would you be able to

join us this year ?? Please contact Betty

Milam at [email protected] Thank

you.

GEM OF THE MONTH

By Diana Cohoon

Our gem is a fairly new member, and she

is originally from Santa Cruz, Ca. She

attended Grammar School and High School

in Santa Cruz. Her parents were originally

from Mexico. Her father was a mason and

used to show her rocks of all kinds that

sparked her interest. She attended Cal

State East Bay and her Major was in

Geography. She has been married 16 years.

She first heard about our club at the

Hayward Farmers Market, and decided to

come and check the shop out and go to a

meeting. She has taken several classes at

the shop and does very well. Have you

guessed who our gem is ? Her name is

Endeliza Hampton.

BRAD SMITH BENCH TIPS

DIVIDERS

A set of dividers is a tool I find very

useful in laying out the geometry of a piece

I'm making. It has two needle-like tips with

an adjustment to set the spacing between

them.

They can be used to transfer a

measurement. Let's say you need a 7mm

Wide strip of sheet metal. Set the spacing

between the divider tips to 7 mm on the

ruler. Then lay the sheet on the bench, put

one tip against the edge, and run the

dividers down the edge scribing a line

parallel to the edge.

Dividers can be used to mark equal

segments of a line or arc. For instance

assume a line between A and B that might

be straight or curved, and you want to

divide it into 5 equal lengths. Set the

dividers to an estimate of the distance.


- 11 -

Starting at Point A, use the dividers to

mark off five lengths along the line. If you

end up short of Point B, lengthen the

distance on the dividers. If you end up

overshooting Point B, shorten the length of

your dividers. After a few tries, the length

on the dividers will be the exact distance

you need to mark the 5 segments.

Dividers can let you quickly find the

center of a circular disk. With one tip of

the dividers at the edge of the disk, set

the other tip to an estimate of where the

center might be. Fix one tip of the dividers

at the 3 o'clock position and scribe an arc

with the other tip near the center. Do this

again from the 6 o'clock, 9 o'clock, and 12

o'clock positions. The arcs at the center

will form a small four-sided box. The center

of the box is at the center of the disk.

PIECE OF LEATHER

Leather has a multitude of uses in the

shop. I often use a scrap of it to avoid

scratching the back of a piece of jewelry

while setting stones. It's also great for

times when you need to clamp one of your

tools in a vise, for instance a drawplate.

KIDS KORNER

Kids on the Rocks

By: Elizabeth Bennette, 16 years old

Earlier this month, we had our annual

Mineral and Gem Show, which was, as

always, so much fun. My sister and I had

the opportunity to volunteer at the spinning

wheel, walk around the halls, and purchase

some jewelry. While buying pieces is usually

what we look forward to, we found that one

of the best parts of this year’s show was

talking to some of the visitors about their

experiences with rocks. This year in

particular, I got the chance to visit with

some of the kids who came to the always

popular spinning wheel. For those who aren’t

familiar, the spinning wheel is a kid’s

activity at the show, in which they can spin

a wheel, and win a small collection of

tumbled and polished stones for only 50¢ a

spin. It’s a real bargain (as their parent’s

will happily tell any member), and gets kids

excited about rocks and minerals by

starting them off with their own mini rock

collection. From the last few times I’ve

helped out at the spinning wheel, I have

heard kids gush about how the wheel is

their "favorite part of the whole show" and

how they still have their "pyrite from last

year!" And as a junior member, it's so

encouraging to hear from kids who posses

early interest and appreciation for minerals

and gems. Multiple times throughout the

weekend, my sister and I suggested that

these kids look into joining our Mineral and

Gem Society, and more often than not, the

kids would excitedly tell us that they would.

Getting the opportunity to talk to these

kids about their interest in minerals and

gems reminded me of why I joined MGSCV

7 years ago. At the shop and at these

shows, I was able develop my appreciation

for minerals and gems, and pick up on new

skills, like cabbing, lost wax, and wire

wrapping. All of these processes require

patience and dedication, qualities that


- 12 -

every young person should learn to posses.

Although many may see the Mineral and

Gem Society shop as a place where they can

refine their skills, which is certainly true,

it's also a community that encourages

anyone of any age to pursue their passion.

There's a place for everyone to grow, which

is why it's so important for us to encourage

kids and teens to become members, and

learn more about their own abilities and the

world of rocks and minerals. In order to

promote this participation of young people

in our club, I’ve compiled a list of ways in

which any member could increase a kid’s

interest in minerals, gems, or geology in

general. If any members have children,

grandchildren, nieces, nephews, or cousins

who show interest in minerals and gems,

don’t hesitate to encourage them to join!

1. Talk to them about your favorite gem or

mineral piece or describe your favorite

process that you do in the shop, and

describe why it intrigues you. Maybe show

him or her some of the pieces you’ve made!

Getting a sneak peek into what the club is

really like will make joining seem a bit less

daunting.

2. For younger kids, emphasize the more

basic components of minerals and gems like

colors, shapes, where each rock is found in

nature, so you give them a simple

introduction to the world of geology.

3. Teach kids about rock identifying by

using easy processes like testing the rock’s

hardness, color streak, and opacity.

Performing tests like these will not only

make kids feel like “real scientists,” but will

also make them more confident and

comfortable with rocks.

4. Explain the origins and science behind

rock formation, and describe how each rock

and slab is completely unique. With an

understanding of the history of rocks, kids

will place much more value on each stone,

and appreciate the beauty of nature.

5. Go out and apply some of this newfound

knowledge by going rockhounding, panning

for gold, or even attending a show just like

ours. This day will be a total blast, and you

can put all that you’ve learned to the test!

April’s Birthstone Is Diamond

Of all the rocks on earth, diamonds

are considered to be the best. The name

Diamond” comes for the Greek word

‘adamas’, which means “invincible.”Diamond

is the hardest stone, coming in with a

perfect 10. The base element of diamond is

carbon. The cleavage of diamond is perfect,

in four directions. In its crystal form, they

are isometric, mostly as octahedrons. Most

of us know diamonds as colorless, however

they are found in yellow, red, orange, blue,

green, brown, and black. When found in its

original form, is has a greasy luster.

Although a diamond is extremely hard, it is

brittle. Diamonds are usually mined from

sedimentary placer deposits, but is

originally formed in peridotite of plutonic

rocks. It is usually associated with olivine,

magnetite, and phlogopite.

Diamonds are primarily found in India,

South Africa, Brazil, and Arkansas. They

have been found in placer gravel in several


- 13 -

areas throughout the Motherlode in

California. For jewelry, diamonds are

faceted.

The article that Elizabeth Bennett wrote

is a very interesting article coming from a

kids mouth. I would encourage parents to

read this article and try and get your

children interested in your hobbies, that

includes children of all ages.

I again encourage parents to ask their

children about what they liked about our

show for instance, and help them write an

article to submit for the Petrograph, or any

other show or exhibit they have visited

with you. It can be grand kids or cousins or

any junior member of your family.

Please consider for example taking the

children to the CFMS show in Lodi

California. There will something for

everyone including kids to see and enjoy and

experience. Lodi is a nice day trip and I am

sure it will be memorable one.

Just some thoughts after I read Elizabeth

Bennette’s article. Write to me with some

thoughts on this…….. Diana Cohoon, Editor

Mail the completed form, a check for the dues payable to MGSCV, and a self-addressed, stamped envelope to - MGSCV, Attn: Membership Chair, P.O. Box 2145, Castro Valley, CA 94546. Your membership is active upon receipt of your check and application. It will be processed and membership cards will be mailed to you within 4 weeks. Your email will be added to the list for the Petrograph, our newsletter. Your name will be added to the roster in the lobby at the workshop and in the drawing at the general meetings for cash prizes, if present. We are a non-profit club whose sole purpose is the education of lapidary arts and geological sciences for all who are interested. No products produced in the shop can be sold for profit. All members should have or be familiar with the MGSCV Handbook. A copy is available for review in the club's lobby or one can be emailed to you by sending a

Before any member may operate any equipment or take any class they must have completed an orientation and their

first cabochon. To schedule an orientation send an email to [email protected] with your

name, phone number, and a good time to call you. During the orientation you will learn about the club and get a tour of the workshop. Monday evenings are reserved for beginners only.

Membership dues cover less than 10% of our annual operating costs. It is our annual show that funds the club, workshop and all activities. A requirement of membership is that every member must work at the show for a minimum of 4 hours. The show is always held the first

full weekend of March, so mark your calendars. The show is

fun to work and is the reason we have the best workshop/club in Northern California. Shop services such as rock sawing, casting, special classes (faceting, wire wrap, metal work, etc...) will not be available to members who do not work at the show.
