Many fine specimens can be found at the show.
This purple-blue Zolite is from Tanzania, Africa.
Most tanzanite mined today is of a brown color and is heat treated to the blue color. The stones are heated to temperatures usually ranging from 752ºF (400ºC) to 932ºF (500ºC).

Here are a couple of large well-defined crystal specimens. The one on the left is 119 carats. The one on the right is 93 carats. Both crystals are owned and displayed by Thomas Schneider of San Diego, California. www.tmsgems.com
John Dyer, who is now 24 years of age, became interested with gems when he was only 16 years of age and started faceting gems at the age of 17. Last year he won first place in AGTA's Cutting Edge "Flat Faceting" competitiion. This year he received a third place in the same category. What an accomplishment for such a young man.
John says "I love beautiful things; gemstones, and tropical fish." He went on to say "Love cutting special type of material even if it takes a little longer and has more facets." John cuts about 150 to 200 stones per year on the average. The smallest gem he has faceted on his "UltraTech" faceting machine was only 2 mm in size. His largest was 126 carats. His favorite shape is the trillion cut because he finds this type of cut to be exceptionally brilliant.
John's worst unforgetable experience happened when he was faceting a larger red beryl. Keep in mind that this particular red beryl was unusually large and cost him $2,000.00 in the rough. While in the final stages of faceting the stone, it split into three pieces. Just think of the amount of material that was ground away trying to cut the larger stone. He was counting on maintaining the large size stone because such a large faceted stone would have brought a premium for its rarity. Now it is three smaller stones of much less size rarity.
John and his dad have spent much time in Brazil sometimes six months at a time. Some of this time is spent doing missionary work. In years past, John prayed that God would give him a special talent. Yes, God does answer prayer. John's success together with his accomplishments bears witness to his God given talents. John is now experiminting with carving geometric designs combined with faceting, similar to Michael Dybers work. John's latest creative cuts and designs are called "New Optix" and "Dreamscapes." www.finecolor.com
Geode and Nodule Slices
Over the years one can find a lot of slices of nodules and geodes that range in sizes from 2" to 7". But, rarely would one find them 12" to 18" in size. Above are photos of some that are in the 12" to 18" size range.
Wayne McGee (on the right) of London, England, is about to purchase a fossil fish from Carl Ulrich (on the left).
Carl, who lives in Kemmerer, Wyoming, has been digging for these fossils and preparing them since 1947. It all starterd when he started tinkering around the Green River Basin area, found a fossil, prepared it and then sold it. Carl stated "I strive for quality, not quantity."
Carl's wife, Shirley, is the one who puts the frames on.
We found these carvings to be of interest
The lizard rock in the left photo is about 20" long. The frog pices is about 6" across.

Some nice material and interesting cuts
come from the cutters of famous
Idar Oberstein, Germany
Carvings by Paul Hawkins and Susan Zalkind are intricate, delicate, real looking, and artiscally beautiful. An example of their fine work is seen in the white alabaster rose ($30,000). They used a special alabaster that comes from an old gypsum mine. It took two years to complete the rose. Their work has appeared in the January 2000 issue of Lapidary Journal
They now teach carving in after school or summer programs.
Faceted and Carved Ametrine
Lek Ho, of Bangkok, Thailand, faceted and carved this 202 carat Ametrine into an interesting shape using a special machine. She wants $3232 for the piece. She is currently the General Director of JEWELRY PRO CO., LTD, having two offices in Bangkok, Thailand. firstname.lastname@example.org
Years ago, I remember rooms full of Kunzite coming from Afghanistan or Pakistan, but nowdays, one can hardly find a large superb piece with good color. However, this year We did find a nice piece of rough from Brazil.
Jeff Schaezle has some nice artistic cavings and carvings that reflect realism.
This 12" size crystal specimen from China is the world's largest scheelite crystal weighting in at 21 kilos (about 47 pounds). Until now the former heavyweight champion was a mere 1/5 the size.
