Faden Quartz

Waziristan Ophiolite, North Waziristan
FATA Federally Administered Tribal Areas,
Pakistan
4.8 x 4.1 x 2 CM (miniature)
price: $135
Spring 2020
A perfect flat style Faden Quartz with very clear line or "string" in a very clear prism. Textbook form and excellent condition, from the incredible find a few years ago in Waziristan. Faden Quartz is fairly rare world wide but this find was so productive that it is still possible to find a choice specimen at a very reasonable cost. As an extra, this has a very slight twist or bend to the main crystal. Remarkably the edges are all perfectly sharp and complete.
Tetrahedrite with Dolomite
stock #19.1-513
Huanzala Mine, Huallanca district
Huanuco Department,
Peru
6.5 x 5 x 1.8 CM (cabinet)
price: $480
Spring 2020
A particularly esthetic Tetrahedrite with very sharp crystals over 3 CM. The main crystals are flattened Tetrahedra and have very good luster, distinct striations and a good metallic sheen. In fine condition, the front or main face is clean and undamaged, there is contacting on the back and outer side edges that is not seen on display. Impressive specimen of this usually non-esthetic Sulphide specie, Very choice for the locality and a fine Tetra from anyplace.
Silver on Copper
stock #17.1-624
Keweenaw Co.
Michigan,
United States
4.6 x 2.7 x 1.6 CM (miniature)
price: $350
Spring 2020
A classic USA "halfbreed" cluster of crude crystals with a sizable percentage of Silver. Ex Less Hitchings collection, the main "glob" of Silver is 2.3 CM across and has distinct color, form and relief from the Copper. The specimen was purchased in 1967 and as was typical at that time has only the area locality (Keweenaw Penninsula). Good halfbreeds have always been appreciated as classic for the UP, and are unique in the world. This one is particularly rich and esthetic, weighs 57 grams, quite dense for the miniature size.
Fluorite with Barite
stock #20.1-120
Komshejeh Mine, Komshejeh, Ardestan County
Esfahan Province,
Iran
6.7 x 6.2 x 3.4 CM (cabinet)
price: $450
Spring 2020
Zoned cubes of Fluorite with complex stepped etching on most faces in an attractive cluster from Iran. The associated bright white Barite blades adds a nice contrast. The Fluorite is mostly a blue color with a violet to pink core best seen in the largest crystal. Some color change is noted under different light sources. In very good condition as seen. Not much Fluorite from Iran makes it to the western mineral markets, this specimen is especially attractive and reminds us of the structure of some Spanish Fluorite but is clearly different on close exam.
Bournonite on Pyrite with Quartz
stock #20.1-131
Trepka Complex, Trepka Valley
Kosovska Mitrovica,
Kosovo
6.6 x 3.8 x 3.6 CM (cabinet)
price: $420
Spring 2020
We see very few Bournonites from Trepka and almost never of good esthetics. This is a very pretty specimen with the best quality we have ever seen. The most prominent Bournonite crystal is perfect, undamaged 1.4 CM in diameter and has bright metallic luster. It is a textbook quality twin with cogswheel form on the edges. The whole piece has choice contrast with brilliant Pyrite forming most of the matrix. Trepka has been known as an excellent source of other Sulphides. This new find was small but had impressive Bournonites which is certainly newsworthy and exciting.
Lazurite -well formed crystal on Marble
stock #19.1-080
Laduar Medam, Sar-e-Sang District, Koksha Valley, Khash and Kuran Wa Mun
Badakshan,
Afghanistan
5.5 x 5.3 x 3.4 CM (cabinet)
price: $560
Bright blue and very well exposed on contrasting matrix, this is a striking specimen. In fine condition the form is complete with edge modification clearly visible, and just under 3 CM across. Typically the faces of these crystals are never very lustrous and can be fairly rough or crude. This specimen is about as lustrous as these get, the crystal faces show some course texture but are way more smooth than is normal. From finds a few years ago, a very attractive and clean piece.
Rutile on Hematite
stock #20.1-177
Novo Horizonte
Bahia,
Brazil
3.6 x 3.4 x .2 CM (miniature)
price: $120
Spring 2020
Epitaxial arrangement of Rutile needles in the six ray form that is famous from this locality in Bahia, Brazil. A choice small example of metallic silver-black Hematite crystals with typical very flat habit hosting radiating needles of Rutile. Close exam of the Hematite faces shows complex striations and some embedded Rutile.
Augelite
stock #20.1-102
Rapid Creek, Dawson Mining District
Yukon Territory,
Canada
4.6 x 3.2 x2.3 CM (miniature)
price: $480
Spring 2020
Superb, larger sized Augelite crystals of top quality in an esthetic cluster. Killer condition (no damage) and with the largest crystal 1.6 CM. Augelite is a rather rare Phosphate only found in such fine crystals like this from two localities worldwide. This specimen is exceptional for the Rapid Creek finds and has fine zoning, sharp, lustrous faces, nice color and some gemmy areas. This remote area of the Yukon has been a world class source of fine Phosphate specimens. The Augelites from here are distinctly different from the the newer finds at Mundo Nuevo (Peru).
