Quartz- "prase" included by Hedenbergite
stock #19.1-084
Serifos Island, Cyclade Islands
South Aegean, Greece
5.5 x 3.1 x 1.7 (small cabinet/large miniature)
price: $90


A cute classic Greek "Prase" or "Prasm" Quartz with good green color, translucence and sharp tapering crystals. Serifos Quartz has been a long known and collectable variety, it has a very distinctive habit that is only known from a few other skarn deposits worldwide. These have become quite pricy on the market, this one is in good shape, has only very tiny chips that are hard to see by naked eye, and is very reasonably priced for one of these.
Calcite "butterfly twins" with Hematite
stock #18.1-657
Leiping Mine, Leiping, GuiyangCo., Chenzhou Prefecture
Hunan Province, China
4.3 x 3.2 x 2.7 CM (miniature)
price: $280


A juxtaposed pair of "butterfly" twin Calcites with bright faces, fine clarity and red Hematite phantoms. From the last mining at Leiping, these are excellent examples from this locality. These twins made big news in the mineral world when found in 2002, partly because they looked so much like the classic British twins from over a century ago. Sharp. clean and elegant these are modern classics that look like the vintage old world classics.
Hexagonite - rare terminated Mg Tremolite
stock #19.1-377
Gouverneur Mine, Fowler, St. Lawrence County
New York, United States
2.8 x .8 x .3 CM (thumbnail)
price: $800


A rare, choice gem clear thumbnail of lilac color Hexagonite (var of Tremolite). The termination on this is complex being made of many tiny points in a tapering structure. Transparent with some color zoning seen when backlit. I believe that St. Lawrence County is the only place where this mineral occurs being found at just 4 locations. However only the Gouverneur Mine ever produced any of this sort of clear terminated crystal and not many of them. This was named when it was thought the crystal form was Hexagonal, however it was later determined to be Monoclinic. The crystal here is in fine condition, has clear striations along the prism faces and a very rich color.
Stannite, Quartz and Arsenopyrite
stock #18AX-15-251-(C288)
Yaogangxian Mine, Yizhang County
Hunan Province, China
7.1 x 4.3 x 4.2 CM (cabinet)
price: $650


From the "golden age" of mineral finds at Yaogangxian, this is a super choice Stannite. Ex Shields Flynn collection, the Stannites are bright brassy, well formed, undamaged and very rich. This specimen was exhibited at Tucson in the TGMS displays in 2005 celebrating the minerals of China. Most pieces from this find had much more Arsenopyrite and or Sphalerite than Stannite, this is almost all Stannite with clear Quartz crystals adding a nice accent. Most will agree that the old Yaogangxian finds were the best ever found. This specimen is well better than typical and now Chinese Stannite is rarely available in such size and attractive quality.
Kyanite with Quartz
stock #19.1-376
Barra do Salinas Mining District, Coronel Murta
Minas Gerais, Brazil
9.7 x 4.1 x2.3 CM (cabinet)
price: $220


Large terminated Kyanite crystals with deep indigo blue color are embedded in and standing on massive Quartz. The smaller crystals are somewhat transparent the larger ones are translucent and show several forms of terminations. The Kyanites from this area of Brazil are some of the most attractive in the world yet are still affordable. This one has color that is more intense than most, in person it is a rich inky color that very few minerals in the world show.
Elbaite -Rubellite gem crystal
stock #19.1-332
Cruzeiro Mine, Sao Jose de Safira
Minas Gerais, Brazil
3.5 x 1 x .7 CM (small miniature/ large thumbnail (toenail))
price: $800


100 percent gem grade Rubellite, mostly a fine cranberry red color with a lightly yellow zoning at the termination. An older Cruzeiro (Brazil) crystal the color is unusually intense for this locality, this looks similar to some Santa Rosa and Jonas mine crystals yet has a sightly different hue. In excellent condition as seen, with even a little backlighting this glows like red glass. The inside is very clean, this is all facet grade that has avoided the cutting wheel. Choice and better in person. Ex John Buckley collection we think this is a 1970 era piece.
Elbaite -gem Tourmaline
stock #19.1-342
Usakos, Karibib District
Erongo Region, Namibia
2.7 x .9 x .9 CM (thumbnail)
price: $160


A single, doubly terminated and gemmy clear Elbaite crystal from the Karibib. Namibian gem Tourmaline of any quality has become quite uncommon, it was last being found almost 20 years ago. Complete and in nice condition this one shows the striated faces and flat terminations that is typical of these Karibib crystals. Nearly all facet grade, the interior is transparent and clear deep green.
Smithsonite -very fine Moroccan
stock #19.1-374
Touissit, Touissit-Bou Beker Dist., Jerada Province
Oriental Region, Morocco
10.6 x 7.3 x 4.1 CM (cabinet)
price: $2750


Large cabinet specimen of well crystallized and very lustrous Smithsonite from the Touissit Mine (Morrocco). The crystals are transparent and when magnified many show color zoning and phantom of a reddish core. Botryoidal and "finger" growths are fully covered by sharp, bright crystals. The color is a light green-blue hue and contrasts nicely with the reddish matrix. In fine condition, Smithsonite from this locale have never been very common (the mine has been closed for decades) and now top pieces are quite rare. This is a sizable display specimen with excellent impact, a fine addition to any serious Smithsonite suite or Moroccan collection.
