Realgar -doubly terminated crystals
stock #6.2-838
Shimen (Jiepiayu) Mine, Shimen County, Changde Prefecture
Hunan Province, China
4.5 x 3.3 x 1.3 CM (miniature)
price: $380


Sharp, bright gemmy red Realgar with intense color. This specimen has minimal matrix and has not been displayed in bright light so it is still very impressive. This was mined in 2005 so it has held its color very well. Minimal bruises on a few edges are not easily seen by naked eye and the main crystals are in fine shape. The Shimen mine was at one time a prolific source of super (maybe the worlds best) Realgars, but it is no longer operating. The backside of the specimen has just a hint of matrix on it and is contacted where it was attached but the rest is very well crystallized and nearly all crystals show double terminations. Unusually fine for one of these.
Tanzanite (gem blue Zoisite)
stock #7AE-353
Merelani, Umba Valley, Lelatama Mountains, Arusha Region
Manyara Region, Tanzania
2.2 x 1.4 x 1.1 CM (thumbnail)
price: $350


A Tanzanite crystal with excellent color change. This is well terminated, glassy deep blue to purple crystal in good condition. The tip of the termination is especially transparent and shows a nice blue "cloud" inside. The backside of the crystal shows a more complex area that has stepped faces and is likely a recrystallized contact. A nice specimen of the specie that is reasonably priced
Enargite -Classic locale
stock #16.1-601
Leonard Mine, 3800 foot level, Butte
Montana, United States
5.2 x 4.8 x 3.9 CM (small cabinet/ large miniature)
price: $380


A cluster of unusually bright, lustrous and sharp Enargite crystals with a few small Pyrite and Quartz on the edges. In excellent undamaged condition with Enargites free standing up to 1.7 CM. A choice, classic Leonard Mine (Butte, Montana) specimen from the golden age of mining there. The flashy luster on this black Copper Sulphide is quite esthetic (and even attractive for a black mineral)compared with the more usual sooty black specimens.
Cerussite - blue-green inclusions
stock #18AX-29-114
Mina Ojuela, Mapimi
Durango, Mexico
6.8 x 4.4 x 4.2 CM (cabinet)
price: $490


An incredible Ojuela Cerussite that is a mix of colorless, green and nearly black Cerussite crystals with minimal matrix of Sulfides, mostly Pyrite. From a find about 5 years ago there were not many as fine as this. Slender, flattened and blocky prismatic habits with and without twinning in exceptional condition. The quality is amazing for this delicate mineral. The darkest Cerussites are included by a dark Sulfide, probably Galena. The green-blue color is an especially nice touch when seen on the clearest crystals. This could be trimmed to a killer miniature but the overall specimen seems to have greater mineralogical interest if kept intact.
Calcite - unusual habits with Clinochlore
stock #15.1-589
Nikolaevskly Mine Dal'negorsk
Primorsky Kray, Far Eastern Region, Russia
8.2 x 4.4 x 4.3 CM (cabinet)
price: $350


A complex older Dalngorsk specimen that displays very well from several angles. These Calcites are gemmy clear and some have sharp mushroom like caps on the terminations of Scalenohedrons. The face details and ice-like etching makes these especially impressive in person. In excellent condition as seen, this is not anything typical and certainly a great addition for any Calcite collection or Dalngorsk suite.
Diopside- Chromian green with Grossular
stock #18.1-741
Orford Nickel Mine, Brompton Lake, Sherbrooke
Quebec, Canada
5.9 x 4.4 x 4.2 CM (cabinet)
price: $375


The so called Chromian Diopsides from the famed Orford Nickel mine are quite prized. We are told that the color may be due to Nickel and not Chrome but either way these are very attractive and uncommon. This one has unusually fine apple green hue. The largest crystal is 1.7 CM and all are gemmy with very glassy luster. Normally the larger crystals are opaque, and a yellowish to grey color. Such bright green clear crystals are usually only microscopic. Tiny deep green Grossular are also present as are Calcite crystals. The tiny crystals add a lot of sparkle in person.
Hydrozincite
stock #7.AE-533
Muqiaomian Depsit, Xinlu-Shuilyanba Quanzhou County, Guilin Prefecture
Guangxi Autonomous Region, China
5.6 x 4.5 x 3.3 CM (cabinet)
price: $390


From the one time find over a decade ago that produced some of the worlds best ever Hydrozincites. This is a very well formed example with perfect form and fine luster. Hydrozincite is not normally thought of as an esthetic mineral but this is certainly very attractive. These were at first mistaken for Aragonite with odd luster but on closer study proved to be much rarer and with amazing quality. We have not seen any like this for sale in years.
Euclase - Gem crystals with blue zoning
stock #18.1- 745
Alto de Giz Pegmatite, Equador, Borborema mineral province
Rio Grande do Norte, Brazil
2.4 x 1.8 x 1.5 CM (thumbnail)
price: $480
Dec 2018

Gemmy sharp and lustrous cluster of transparent, colorless Euclase crystals showing the deep indigo blue zone inside. An older specimen from finds years ago at Alto Do Giz. The crystals are doubly terminated, textbook sharp and nicely striated. In very good condition though some cleaving is noted on the backside but this presents very well and shows no damage on display. A nice clear Brazilian Euclase with the most desirable color inclusion.
