Calcite - color zoned with phantoms
stock #7AE-144
San Antonio Mine, Santa Eulalia, Aquiles Serdan
Chihuahua, Mexico
10.8 x 7.9 x 3.7 CM (cabinet)
price: $360


A striking color zoned Calcite from the San Antonia Mine, Santa Eulalia. This was mined about 20 years ago, and shows two generations of Calcite with different habits. Brilliant red color and with bright luster, the red is most likely from Hematite. The display face is in excellent undamaged condition, the only damage is along the outer edges where it was removed but even that is minimal. A distinctive, colorful Mexican piece that is much more impressive in person.
Duftite on Quartz
stock #17.1-795
Black Pine Mine, Flint Creek Valley, John Long Mts., Granit Co.
Montana, United States
12.8 x 9.3 x 4.2 CM (cabinet)
price: $650


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.
Vayrynenite -rare gem crystal
stock #19.1-299
Shengus (Shingus) Haramoush Mts. Skardu District
Gilgit-Baltistan, Pakistan
1.7 x 1.3 x .6 CM (thumbnail)
price: $450


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.
Adamite
stock #6.2-1052
Mina Ojuela, Mapimi
Durango, Mexico
5 x 4.1 x 1.1 CM (miniature)
price: $380


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
stock #19.1-298
Dassu, Braldu Valley, Skardu District, Baltistan
Gilgit-Baltistan, Pakistan
2.8 x 1.9 x 2 CM (thumbnail)
price: $140


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.
Valentinite
stock #19.1-329
Pribam
Bohemia, Czech Republic
6.8 x 4.7 x 1.7 CM (cabinet)
price: $130


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.
Anglesite with sulfide inclusions
stock #16.1-662
Tsumeb
Otjikoto Region, Namibia
2.3 x 2.2 x 1.5 CM (thumbnail)
price: $220


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.
Pyromorphite -unusual color for locale
stock #AX-19-049
Daoping Lead-Zinc Mine, Yangshao
Guangxi Autonomous Region, China
6.1 x 4.5 x 2.9 CM (cabinet)
price: $1400


Delicate sprays of glassy, transparent and sharp Pyromorphite crystals covering all sides of this specimen from Daoping. Minimal matrix, this Pyro has unusual pale colors mixed with a few of the more typical bright green hues. In impressive condition overall, this is incredible for such a delicate specimen. The pointed light yellow to brown crystasls are arranged in radiating clusters and bunches. The Daoping mine at Yangshao has become world famed for top Pyromorphites. This is a fine quality specimen and it is much more rare to see this color and habit so well presented.
