Elbaite with Lepidolite
Virgem do Lapa
6.8 x 1.6 x 1.4 CM (cabinet)
A doubly terminated gem Elbaite crystal is partly wrapped in a "cloak" of Lepidolite. The Tourmaline color is a mix of green and blue hues, it is zoned but not sharply, the colors grade together gradually. In excellent condition there is no naked eye visible damage or chipping on the Elbaite. With strong magnification two very slight nicks (under 0.5mm) can be found, this is essentially perfect. The "bottom" termination is a flat basal type while the top is a stacked series of angled faces. Especially pretty with backlight, the association with the sparkling Lepidolite makes a nice contrast. Ex Charles M. Noll collection, 18.7 grams
Waziristan Ophiolite, North Waziristan
FATA Federally Administered Tribal Areas,
4.8 x 4.1 x 2 CM (miniature)
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
Huanzala Mine, Huallanca district
6.5 x 5 x 1.8 CM (cabinet)
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 and Copper
6.7 x 3.1 x 1.7 CM (cabinet)
A hackly mass of Copper holds some areas of crudely crystalline Silver. The largest zone of Silver also has a few areas of Copper growing on the Ag which is less common than the other way round. A good mixed native element specimen from the Hitchings collection that he obtained in 1970. This sort of association is unique to the upper Pennisula of Michigan.
Silver on Copper
4.6 x 2.7 x 1.6 CM (miniature)
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.
A sizable and well crystalized specimen of three Phosphate species together. The main ingredient is the Paravauxite in distinct pale green to colorless crystals up to 8 mm long though most are a bit smaller. Some of these near the edges have partly or fully altered to Sigloite (tan color). There are a few sprays and radial balls of blue Vauxite scattered about as well. This specimen from the Ruth and Andy Palmer and the William Hladysz collection. A very nice piece that is rstill elatively affordable for these uncommon species.
Fluorite with Barite
Komshejeh Mine, Komshejeh, Ardestan County
6.7 x 6.2 x 3.4 CM (cabinet)
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.
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.
