Grossular v. Hessonite- large single XL, Classic
stock #17.1-035
Zulova, Jesenik, Olomouc Region
Moravia, Czech Republic
6.3 x 5.2 x 4.8 CM (cabinet)
price: $390
Spring update

A big, complete Garnet crystal with honey brown color from an uncommon locality, Zulova in the Moravian area of Czech Republic. This is quite exceptional for this old locale and the condition, size and quality are top. Some surface alterations are seen on faces with a deeper red color beneath. Matt luster overall but some faces have a glassy surface as well. All examples I know from this location are much smaller, darker and usually have considerable damage or wear. One old label is included.
Grossular -gemmy etched crystal cluster
stock #18.1-AX-24-267
Jeffrey Mine, Asbestos
Quebec, Canada
3.4 x 2.6 x 1.8 CM (miniature)
price: $380
Spring update

A completely transparent cluster of Garnets that has no matrix and yet also has good isolation of the largest crystals. A relatively three dimensional specimen that has an unusual "etched" or melted look to several crystals. With strong magnification this is seen as complex modifications to edges and very fine striations that are not typical. An attractive and (in my experience) rare oddity that is also affordable. Internal clarity is near 100 clean facet grade gem.
Beryl var. Emerald wih Quartz
stock #18.1-056
Mina Amarillial, Cosquez, Municipio de Muzo
Boyaca, Colombia
5.4 x 4.8 x 2.6 CM (cabinet)
price: $850
Spring update

A two-sided specimen holding dozens of light to mid green Emerald crystals that are intermixed with Quartz crystals. Very unusual for a Colombian Emerald specimen, the usual association in Calcite. Prior to our finding this material the only Quartz matrix I have seen or know of for Emeralds is at Penas Blancas and it is very rare there. This little known cut near Coscuez has now produced a few of this rae combo. A choice and rare piece with many small, very clear Emeralds covering both sides of the matrix. With magnification the quality really stands out.
SOLD Sphalerite (flowerlike) on Dolomite
stock #SOLD 18.1-AX16-188
Lockport, Niagara County
New York, United States
2.4 x 2.3 x 1.4 CM (thumbnail)
price: $0
Spring update

A killer thumbnail hosting a perfect cluster of gemmy Sphalerite. From a little known find in Lockport, NY, this would be a superb Sphalerite from anyplace. The luster is glasslike and even at 40 x magnification the condition is perfect damagewise. A choice, competition grade thumbnail.
Spinel- Gem octahedron
stock #18.1-162
Pein Pyit (Painpyit), Mogok, Sagaing district
Mandalay division, Myanmar (Burma)
1.5 x 1.3x 1.2 CM (thumbnail)
price: $450
Spring update

Transparent, blood red and complete. A single octahedron of Spinel from the famed Mogok gem field. The edges show typical rounding or "melted look" that is classic for this area. These are extracted as gem gravels by hand work as has been done for centuries. Since the mineral is so hard and abrasion resistant the form stays relatively sharp and lustrous. with 10-20 x magnification only slight signs of abrasion can be seen. 16.8 Carats in weight. A nice colorful octahedron of "ruby" Spinel.
Sphalerite- Gem crystal
stock #18.AX- 161
ZCA Mine number 4, Balmat, Balmat-Edwards District, St. Lawrence, Co.
New York, United States
1.2 x .8 x .4 CM (thumbnail)
price: $110
Spring update

A small, gem clear single crystal of amber colored Sphalerite. Complete and undamaged from the remarkable finds decades ago at the ZCA (Zinc Corp. of America) mine in Balmat, NY. A "textbook quality" crystal, despite the small size this has good eye-catching luster and color.
Sapphire -blue Corundum crystal
stock #18.1-153A
Ohngaing (Ohn Gaing; Ohn Kai)Mogok Valley, Mogok Township, Pyin-Oo-Lwin
Mandalay division, Myanmar (Burma)
3.7 x 2.1 x 1.8 CM (miniature)
price: $350
Spring update

A complete, somewhat crude, deep blue Sapphire crystal. Several small pits and cavities in some faces are filled with muscovite and some purplish sapphire chunks as well. Some transparent and translucent areas are seen but the majority is nearly opaque. A nice example of a real Mogok Sapphire that is not top gem grade but also not priced in the 6 figures. Nice specimen, these are not often available as every scrap of color seems to be cutup very quickly.
Ruby- red Corundum
stock #18.1-154A
Ohngaing (Ohn Gaing; Ohn Kai)Mogok Valley, Mogok Township, Pyin-Oo-Lwin
Mandalay division, Myanmar (Burma)
3.1 x 1.1 x .9 CM (small miniature/ large thumbnail (toenail))
price: $850
Spring update

Rich red color Corundum crystal that is crude but complete and translucent throughout. Burmese (Mogok) Rubies are the most valued Ruby in the world and very few crystal specimens are available. This is a complex crystal with some etching (looks "melted" in spots) and recrystallization. Looks good on all sides, this is a sizable 24.5 Carat stone.
