Duftite on Quartz
Black Pine Mine, Flint Creek Valley, John Long Mts., Granit Co.
12.8 x 9.3 x 4.2 CM (cabinet)
A large plate of Quartz crystals up to 2 CM in size are thickly coated with Duftite in olive-green spheres. An old specimen from the Black Pine Mine that is famed for the great Veszelyite finds there. I have not seen another specimen quite like this from any USA locality it looks like a dark botryoidal Tsumeb Duftite on a Montana Quartz. An unidentified coating of brighter yellow is also present and adds some contrast. it is a very significant and sizable Duftite specimen with a lot of character. In good condition overall there are a few tiny chips on some Quartz but most are perfect and undamaged. The Black Pine mine has a complex and wonderful mineral assemblage including many uncommon associates. This piece is significant for the locale is the best USA Duftite I know of. Ex Chris Amo collection.
Calcite with Realgar inclusions
Shimen (Jiepiayu) Mine, Shimen County, Changde Prefecture
Simply incredible! A brilliant red cluster of calcite on matrix with small realgar crystals. Killer esthetics. We obtained this at the mine in 2003 and sold it shortly after- it was the best of the find. Since then we have not seen anything like this. We are pleased to have it back again for resale, The largest calcite crystal is 7.2 CM, and the piece displays well from multiple angles, but it does have a cleave on the backside. The red color on the calcite is from both a coating and inclusions that is primarily realgar, some recent analysis of similar materials have fund trace amounts of some rare rsenic minerals, this one has not been tested for those. Really striking color, the display side has no noticable damage. This will really jump out of any calcite display!
Vayrynenite -rare gem crystal
Shengus (Shingus) Haramoush Mts. Skardu District
1.7 x 1.3 x .6 CM (thumbnail)
The rare gem mineral Vayrynenite has been found in a very few places worldwide, but by far the best have come from Pakistan, in small pockets sporadically over the past thirty years. This is from a pocket found in 2017 which was the last good find. Good orange red color, transparent to translucent showing very rough, crude terminations that at first glance look broken. These seem to have been etched and recrystallized at some point in the past. Well defined striations on the prism faces, this has well above average color, luster and transparency in a simple thumbnail.
A super esthtic, pale blue gem Topaz on a twin Microcline base and a small Quartz crystal on the termination. In excellent condition as seen, this is an especially esthetic Spitzkoppe specimen, this locality has produced the best Topaz from Namibia. The Topaz has bright glassy luster and fine striations across the prism faces. A top notch display grade Topaz that is fully transparent and undamaged.
Mina Ojuela, Mapimi
5 x 4.1 x 1.1 CM (miniature)
Inter-connected half-balls of bright green Adamite forming a plate with minimal matrix. The balls have bright luster and are composed of distinct small curved crystals. Early 1960 vintage specimen from Mina Ojuela, the backside of this is flattened being contacted with a minor amount of adhering matrix. The front is in fine, undamaged condition. Distinctly different from more recent finds and brightly fluorescent.
Apatite (Fluorapatite) on Albite
Dassu, Braldu Valley, Skardu District, Baltistan
2.8 x 1.9 x 2 CM (thumbnail)
A clear pink Apatite with a wispy phantom nicely exposed on a white Albite matrix. Intense yellow Fluorescence and a clean, glassy luster add to the interest of this choice thumbnail. Displays fine from several angles, this is in excellent condition.
6.8 x 4.7 x 1.7 CM (cabinet)
An old specimen from the classic mines of Pribram, densely covered with Valentinite crystals. The Valentinites are of the elongated type with complex cross section. These crystals reach 1 CM and are both free standing and flat laying. There are several complete, undamaged crystals but there are also several with clearly visible damage. While this is not a piece or perfectionsts it is better than typical for this delicate mineral and is a lower cost, classic specimen. Ex Vrazel collection.
A fine thumbnail of Anglesite showing the entire crystal form perched on a sliver of matrix, from Tsumeb.
This habit of Anglesite with the zoned dark inclusions is distinctive. In fine condition, no damage can be found even at 20X magnification. One end of the crystal has both Pyrite and Galena in small crystals and masses on the exterior faces, the other end is uncoated except for some micro Cerussites (white) not seen without good magnification. There are dark inclusions of what is most likely Galena seen at several places but mostly near the terminations as dark zones. The matrix here is mostly a druse of small Anglesites that are black, lustrous and thickly included with Sulfides. A choice Tsumeb piece and a nice Anglesite.
