Synthetic Faceting Rough

New Man-Made Gemstone Material- Cristinite So new and so unique, we are giving it a special page!

Cubic Zirconia

Cubic Zirconia this is zirconium oxide, not to be confused with the natural stone, zircon. This is dense material with a specific gravity of about 5.8(+/-), no cleavage, and very low heat sensitivity, if any. It makes a beautiful and interesting gem due to it's high (2.15-2.18) RI. It cuts relatively quickly and easily, but can offer some challenge in polishing. The traditional "best" combinations for polishing CZ are 100k diamond on typemetal or 50k diamond on tin. We have also had good results with 50k diamond on a BATT lap. Others have reported having polishing success with 50k diamond on ceramic, zinc, Fast Lap, Last Lap, and even wax.

Mt. St. Helen's Ash

Mount St. Helen's Ash, melted into glass. This is somewhat of a local celebrity here in the Northwest- gems made of he melted ash from the May 18, 1980 eruption of Mount St. Helen's. This was manufactured by the folks that created one of the original trademarks for this material back in 1980. and it comes in the beautiful and ever popular bright blue with a hint of green, as well as pastel green/blue pieces. Some pieces may have some small bubbles, but most do not. This material is created in long rods, generally round to oval shaped, and most are between 6 - 8 mm in diameter.

"Boro-Silicate" Gem Material

"Boro-Silicate" Gem Material better known as glass, is good for pendants and earrings. The color does get lighter for smaller gems, which is true for most gem materials.
Facet with a metal bond 600, prepolish with a fine lap (1200 or 3000), and polish with cerium. Polish with light pressure to avoid chipping facet edges.

NOTE:
The rough is sawed blocks of material; the PICTURES are examples of finished gems to SHOW THE COLOR, not represent what the raw material looks like.

• Tourmalike Laser Gem- This is a color change item: pink in sunlight and incandescent light, and a pleasing medium green in fluorescent light. $ 0.12/ct.
• Tanzanite Jewel-Lite- This is a blue/violet color similar to deep colored Tanzanite. It's one of our best sellers. $ 0.10/ct.

YAG

YAG (Yttrium Aluminum Garnet)- this is one of the finest man-made gems available. It has amazing, very saturated color, and a high (1.833) RI. With a hardness of 8.5, it makes for a very beautiful and durable stone for jewelry. It facets almost like typical garnet; facet with 600 grit, prepolish (preferably) with a very fine lap (I like the 1600 Dyna Disk), and polish with alumina on tin (tin alloy, or Fast/Last Lap). Some faceters use 50k diamond on the above laps, also.

Man Made Spinel

Man Made Spinel - One of the finest gems- with a hardness of 8 and with a high (1.72) RI, which makes it a bright and beautiful gemstone. This material facets easily, seems quickest with a very fine prepolish (3k powder on a BATT or Wizard lap), then 50k diamond on BATT, or alumina on tin/tin alloy.

Orienting man-made BLUE sapphire: To obtain the best color from flame-fusion split boules of corundum, which have a lighter color density in the center of the boule, place the color in the culet of the stone. This will literally "flood" the stone with color. The picture below is taken from a position of looking down the "long" axis of the boule. Not all blue boules are this light in the center, but the same orientation applies to obtain the deepest color.

All colors and measurements are to be considered estimates only; Please inspect your order when you receive it and form your own determinations. Of course, I offer 15-day return privilege on any unaltered materials for refund, credit, or exchange.
