BOULDER BUSTERS Volume #48 Issue # 4, 2013
PRESIDENT'S MESSAGE
Hello Rockhounds,
Here we are and its April already, and the March auction went very well and I would like to thank the many people who
made it a success. Mel is working on putting together another field trip this month to the opal dig if anyone is
interested. Please get ahold of us if you are interested and if we have enough interest we will get it going.
This month is the Kennewick show, so that adds in another rock hunting for trip for everyone. We got our show theme
for this year “From Rocks to Gems” but still in need of a few of the chairperson positions filled, so see me or Linn if you
are interested in helping out.
I am still looking for someone to fill the secretary position so if you are interested let me know. Get involved it makes the
club more fun, so bring your “show and tell” and we will see everyone on April 12th.
Steve

IMITATION GEMS
Bruce Borgelt
Act II
The making of imitation gems started about 5000B.C. when Egyptians fashioned ornaments of faience, a glazed ceramic that
could be tinted to resemble turquoise. By 1600 B.C., cut glass had appeared, masquerading as any number of transparent
gemstones. During Roman times, in fact, a shortage of the material made glass trinkets more highly prized than many natural
gems. Composite gems made of a color matching imitation gem as the base and a thin layer of genuine stone on top appeared
next.
Most of the effort to create a imitation gem has centered around making a diamond. Many different kinds have been made, but
the Zircon is the most known. Cubic zirconia can be produced in batches of 100 pounds and sold wholesale for a few dollars a
carat, yet its optical properties make it almost impossible to distinguish from diamond by an untrained eye. Since diamonds
consist of only one element, synthesizing them would seem to be relatively uncomplicated. The difficulty is one of technique, of
creating---and containing---the enormous pressures and temperatures needed to pack carbon atoms tight enough to form
diamond. Many early attempts ended in large explosions that wrecked the laboratory. In the early 1950’s, scientists created a
hydraulic press capable of 1.5 million pounds per square inch and a temperature of more than 4,800 degrees F.. Today the same
basic technique produces some 44,000 pounds of industrial diamonds---small diamonds of no particular quality used as an
industrial abrasive. In 1970 a version of the same process (temperature and pressure must be held for over a week) was used to
create a few gem-quality diamonds weighing up to a carat. But the cost of producing them was so high that it remains cheaper
to mine gem diamonds.
A laboratory-grown ruby was the first triumph of gem synthesis in 1837. The first rubies created were milky, prone to cracking,
and very small. In 1902 a new process was developed that is still used today to make large imitation rubies.
Synthetic emeralds were first created in the late 1930’s. It is not easy to distinguish synthetic and natural emeralds, though the
synthetic variety is often more transparent, richer in hue and in some ways more perfectly formed than natural emeralds. The
latter is the easiest way to detect an imitation, using a microscope; the imitation is too uniform and perfectly formed compared
to the natural emerald.
Distinguishing between synthetic and natural gemstones while traveling, calls for vigilance and sometimes even experts lower
their guard. One expert was offered 4 large red rubies while on an expedition to Burma. They looked good and the price was
about half of the U.S. price (about $500,000). He almost bought them, but decided to do some investigation with a microscope.
He determined the gems were a synthetic Kashan ruby, made in Texas for about $100 a carat, then taken into the jungle to be
sold as the real thing.

APRIL BIRTHSTONE IS A DIAMOND
Chemistry:C, elemental carbon
Class:Native Elements
Subclass:Non-metallics
Group:Carbons
History of diamond
Diamond is the most familiar gemstone and it has a rich and
interesting history. Diamonds are known for their prismatic beauty
and hardness, and they are highly valued for these and other
qualities. At one time, it was even thought that if you took a
diamond into bed with you, it would cure your illness!
Science of diamond
Diamond is a form of carbon with a tightly bound crystalline
structure. It originates deep inside the Earth under intense pressure
and high temperatures. Diamonds are brought up to the surface by
very deep-seated volcanic activity. Diamond-bearing volcanoes are
called kimberlies, and they erupted millions of years ago.
Interestingly, both graphite (used in pencils) and diamond are forms
of carbon, but they have very different structures and properties:
graphite is opaque and soft, while diamond is transparent and the
hardest mineral on Earth. These differences occur because diamond
crystallizes in the isometric system while graphite crystallizes in the
hexagonal system.
As the April birthstone, diamonds are the ideal gift for a loved one.
And now you have more choices than ever. Get creative and give
the ultimate gift of beauty: a fancy-color diamond. Fancy-color
diamonds are natural, rare and truly exotic gem of the earth.
Diamonds in hues of yellow, red, pink, blue, and green range in
intensity from faint to vivid and generally the more saturated the
color, the higher the value. In fact, diamonds sparkling with intense
color are rare and may be priced higher than a colorless diamond of
equal size. Because fancy-color diamonds are very desirable, color
is sometimes introduced in a laboratory. These are correctly called
color-treated diamonds. When purchasing a fancy-color diamond,
the shopper should ask if any enhancements or treatments were
used to improve its color and/or clarity.
The diamond does not appear to have been known to the ancients
and is not given in any of the lists of birth-stones before the last
century. The diamond, typifying the sun, is the gem of light. Its
color is that of ice, and as the dew-drop or the drop of water from a
mountain stream sparkles in the light of the sun, so the diamond
sparkles, and it combines and contrasts with all known gems. Like
light, it illumines them just as the sun does the plants of the earth.
The diamond, the gem of light, like light itself when broken into a
spectrum, gives us all known colors, and by combining all these
colors it gives us white. Like gold, the diamond was made rare, so
that it must be searched for, and the mines and deposits contain
less of these two substances in a given area than of any other
known materials. As great nuggets of gold have occasionally been
found, so has a diamond been discovered large enough to make the
greatest ruler pause to pay its price.
Quartz crystal is an alternate
birthstone for April.

HELLS CANYON GEM CLUB HISTORY
Some of the old timers will remember Floyd Mossler. Floyd wrote a history of the rock clubs in the
Lewis-Clark Valley, from 1937 to about 1978. His son, Michael has granted permission to the
newsletter to publish. This will be the third of six installments on his story. Enjoy.
At the regular meeting on March 9, 1941, it was decided that a rock display and show would be held
on March 15th and 16th at the Bollinger Hotel. Members were to have their display ready for display
by March 14,'1941. On March 16, 1941 the Bollinger Hotel's advertisement in the Tribune for this day
featured the Club's display of Stones and Minerals in the lobby. Also in the Tribune a headline of half
a column said "Idaho Variety in Rocks - Display Stones of all sizes and colors shown by Local
Rockhounds.
The rest of the year featured the Club's regular meeting and field trips, one of which was a trip above
Harpster for garnet and crystals. Everyone got some garnet and crystals. The field trips were
different than now, it made no difference who found the most of what or where. No one was left out.
Everybody came home with about the same amount of rocks. I wonder if there are garnets up there
yet. Maybe we should go see.
Also one other trip was up above Stites for arrow heads. I still have a few and I know I could go up
there and still find some.
In the year of 1942, the Club got smaller and began to drag. Meetings were not regular. Several
members left for the coast, to work in ship yards and other war projects. Gas was getting hard to
come by for other than essential needs. In the fall of 1942 a meeting was held and a large amount of
the members were present and a lengthy review of the clubs activities of the past 5 years were gone
over. This was printed in the paper the next day along with a notice of the clubs intentions for its
discontinuation. The cause was not due to lack of interest, but due to gas rationing and to conserve
gas and oil and lights and other things to help the war in progress. But, when you would see 2 or 3
persons together with a pocket lens examining a rock, there you would see members of a dormant,
but far from dead Clearwater Rock Club.
Now there was still lots of talk and people still walking around on the hills and rivers and creeks
close to Lewiston but no meetings or Club activities for a number of years. When the war was over
and gas became easier to get, and things got back to normal, people began again to wander out
fishing and camping and rocks and arrow heads began to come back in the lunch baskets. People
began to talk and show one another what they had found.
The urge to get back to rock collecting became the old fever, the rock pox. So in the year 1952 we
started the Hells Canyon Gem Club.
On January 17, 1952 the meeting was held at the College Elementary School Auditorium. C.C. Lame
opened the meeting with a talk on the idea of starting a new Club. All agreed so Mel Stewart was
elected President, his wife Alta Stewart was elected Secretary-Treasurer. Mr. Lame served on the
board of Directors that year with Francis Portorfos and Stanley Miller as Directors. Thirty-eight
people attended this meeting. In May, 1952, we held a small Gem Show at the College Elementary
School. This was more of an exhibit to show people the variety of rocks in this region, but polished
stones and rough ones were displayed, some jewelry also. No dealers - 50¢ admission - 2 days.
Monthly Meetings were once again resumed. With field trips 3 or 4 times the first year and 1 field trip
each year that included a picnic. Watermelon fields were enjoyed now and then. Talks were always
included in each meeting with displays and sometimes demonstrations. We had members from
Orofino, Genesee, Moscow, Pomeroy, Anatone, Culdesac and other small towns.
Just to mention a few of the members then, were Mr. and Mrs. Don Axtell. He was a Wonder Bread
Truck driver from Spokane. She was a school teacher. They are now living in Arizona, near
Page 7
BOULDER BUSTERS Volume #48 Issue # 4, 2013
Quartzsite.
Mr. Mel Stewart was a partner in Lewiston Refrigeration at the time. He and his wife were given a
life time membership in the Club, the only people to have that honor.
Mr. C.C. Lame came in as a member from the old club and several others did like wise. Mr. and Mrs.
Bill Curtis were from the old Club. Mr. and Mrs. Jess Knepper were new members. They were
running a Meat Market and Grocery Store at the time another members were Chauncy and Mrs.
Kunkle. He was one of the most willing workers in the Club and was really missed when they left the
Club. He was a very capable person, an expert Cab maker. He was a carpenter and made a lot of
his furniture in his home and is now engaged in building old time spinning wheels that are of standard
size and really work. He is employed at Camas Prairie Railroad. They are truly fine people.
Esther and Alvin Putman became members. She was one of the most efficient workers in the Club
at that time, getting ads for shows. She has held most all of the offices in the Club at one time or
another including putting out the news letter and so has her husband. He was treasurer for a long
time. They are still very active in the Club today.
Mr. and Mrs. Tom Duffy came in from the old Club. They are now retired but still living on Prospect
Avenue, here in Lewiston.
Mr. Joe Blalock was the 3rd president of the Club ahead of Larry Hansen. He dropped out of the
Club and started up a rock and mineral shop in his home in Clarkston. He named it Hells Canyon
Gem Shop. He was very good at tumbling rock and he hauled home tons of beach agate from the
coast in Oregon. He had a nice shop. He later had some trouble with the rock Club and sued the
Club, but lost the suit. It cost the Club several hundred dollars. This caused trouble in the Club and
several members dropped out and Joe Blalock and others formed a new club in Clarkston, with him
as president. They named it Jewel Crafters Gem Club. It lasted only a couple years and then split up.
Larry and Bonnie Hansen, he was the 5th president of the Club, and served 2 terms, 1956 and 1957.
He started the first rock shop on Main Street. He was a very good workman in making rock jewelry.
He was one of the first big collectors of Sillimanite.
Also a member was Al Fisher, a man of 65 and a carpenter. He was the best Sphere maker the Club
had. He made them from the size of golf balls up to 5 inches in diameter. He made his own
machinery, he also made fine jewelry. He has long since gone to the Great Beyond.
It was during the term of Larry Hansen that the Club put on its first real show that had dealers and
trading and selling and the biggest the Club has ever had.
It was held at Joe Thometz Pavillion in North Lewiston. Five women with Mrs. Putman as chairman
canvassed the town for ads that paid for the show directory. They worked the whole town and North
Lewiston and Clarkston and sold over 60 ads that paid for the directory and some left over. There
were dealers from all over and many local displays. Al Fisher had a Sphere display. The Club, after
all expenses were paid, made nearly $4,000. We featured the Lady in Jade from San Francisco,
California.
There were people from as far away as Florida at the show. Over 3700 people attended the 3 day
show. The Lewiston Broncs Baseball Team played the Tri-Cities team on the days of the show. Boat
rides up 61 miles on the river, had special rates during the show. Potlatch opened the Mill to visiting,
for 2 days and field trips to garnet mines and sillimanite areas. It was a big show.

IMPORTANT MINERAL DISCOVERY ANNOUNCED
A team of mineralogists from The Smithsonian,
The American Museum of Natural History and
NASA have been involved in a detailed study of
the mineral pyrite for the past 10 years. In one of
the most important scientific articles published this
century, Dr. Amy Thyst, Dr. Feldon Spar, and Dr.
Mallard A. Kyte revealed their discovery. Here is a
quote from their article:
“For centuries the mineral known as “pyrite” has
been believed to be composed of iron and
sulfur. Hundreds of so-called miners have died
in poverty because they discarded their “fool’s
gold.” Well-meaning but ill-informed amateurs told them they did not have gold, but pyrite or fool’s
gold. Our detailed studies of the inner atomic bonding of the molecules in “pyrite” have revealed
that pyrite is composed of very little iron and sulfur. As a matter of fact, the iron and sulfur is
present only as an included impurity. Pyrite
is actually a densely packed
variety of gold. We have concluded that “pyrite” specimens should be labeled as “dense
gold.” It is the density of the closely packed gold atoms that gives ‘”pyrite” its hardness. Informed
mineralogists and mineral collectors already know that gold and “pyrite” crystallize in the same
crystal system (isometric, also called cubic). Now we know that this is not by chance or accident.
Curators at The Smithsonian Institution, The American Museum of Natural History, as well as
hundreds of large and small museums around the world have begun the painstaking task of
relabeling their “pyrite” specimens as “dense gold.” It goes without saying that the value of nearly
every mineral collection in the world - museum, professional and amateur - have jumped
dramatically in value due to this important discovery. If you have “pyrite” in your collection, please
change your labels to read “dense gold.” You may also wish to have your collection insured, too.”
And if you believe any of this . . . . . . . . . . April Fools!
