Silver - crystals and wires with Calcite
stock #18.1-265
Batopilas, Andres del Rio District
Chihuahua, Mexico
3.4 x 2.1 x 1.3 CM (miniature)
price: $190

A mix of jumbled wires and elongated crystals of Silver with some chunks of Calcite enclosing some of the wires. From Batopilas, a famed old Silver mine in Northern Mexico. The locality is known for the herringbone habit of crystals but other habits like these are known too. The larger crystals here have a more metallic patina than the wires and seem to be elongated octahedra with sharply pointed terminations.

Fluorite - modified and aligned cubo-octahedral crystals
stock #AX-14-345
Orange River, Namakwa
Northern Cape Province, South Africa
2.9 x 2.2 x 1.8 CM (thumbnail)
price: $160

Dark purple Fluorite crystals that are translucent to transparent in strong lighting. A somewhat unusual locality better known for the red and orange Quartz crystals this is a nice example of this habit. The crystals are edge-modified cubes (cubo-octahedral) aligned with each other. There is no matrix except Flourite which has tiny stepped voids in the flat surfaces. The back and one side are incomplete, the front facing (display face) side is in fine undamaged condition.

stock #13.1-342
79 Mine, Hayden, Banner District, Gila County
Arizona, United States
5.7 x 2.7 x 2 CM (cabinet)
price: $50

A knobby growth of light blue-green Hemimorphite that has encrusted the matrix on all sides. The surface is fully covered by small sparkling crystals which are translucent and quite lustrous. From the 79 Mine, a well-known locality for fine Smithsonite and Wulfenite but which is also home to a wide array of Lead, Copper and Zinc minerals.

Galena - spinel twins, USA
stock #20.1-594
Fletcher Mine, Big Bear orebody, Vibernum Trend, Reynolds County
Missouri, United States
6.1 x 4.4 x 3.8 CM (cabinet)
price: $380

A flat habit spinel twinned Galena perched on Dolomite, Chalcopyrite etc. From the Fletcher Mine (Missouri, USA) the Galena is perfect, undamaged and huge for the mine at over 4 CM across. it is very unusual to see from the USA, there have been a few US finds of these over the past decade but never many. The Fletcher Mine is perhaps the most important locality for these twins and this specimen is top notch for the locale based on crystal size and esthetics. In person there is a slight iridescent patina and a slight golden hue mixed with a gunmetal silver.

Kunzite - etched floater crystal
stock #20.1-119
Laghman Province, Afghanistan
6.4 x 4.1 x 1.7 CM (cabinet)
price: $380

A nice bit of natural mineral sculpture. This single gem crystal is doubly terminated with the "jagged mountain peak" habit and is beautifully etched. The whole has been completely recrystallized and is a perfect floater, there is no damage. Fully transparent with striated prism faces, this looks great from any angle and of course has the strong dichroism that this type of Spodumene is known for.

Digenite - large crystals, classic locale
stock #19.1-799
Leonard Mine, 3800 foot level, Butte
Montana, United States
3.8 x 2.8 x 2 CM (miniature)
price: $750

A superb cluster of very large crystals of Digenite with a sprinkling of Pyrite and Quartz. This is exceptional for the specie and of a quality that is impossible to find in most any collection much less available for sale. Digenite is one of the more rare dark Copper Sulphides, a true mineral lover's specie, it is usually a "non-esthetic" or simply ugly. This piece is a lot more attractive than most. Sizable crystals are incredibly rare, the best were found more than 60 years ago in Butte, this piece is from that vintage. This piece has an early David New label (circa 1967).

Fluorite - spinel twins and chain growths
stock #17.1-308
Hohenstein Massif, Omaruru District
Erongo Region, Namibia
9.3 x 4.2 x 2.4 CM (cabinet)
price: $550

A crazy unusual Fluorite that has an incredible odd crystallization. The whole piece is a mixture of slightly twisting "strands" of linked chain-like growths of crystals that looks "melted". Some of the strands host larger, textbook examples of spinel-twinned Fluorites some of which are color zoned. The whole mass is transparent to translucent, and when backlit is a mixture of purple, green and yellowish colors. This was found on the Hohenstein Massif in Erongo in 2017, part of a small pocket of very strange yet beautiful(to me, at least) Fluorites. This is a complex specimen, interesting from most any angle, very hard to describe but for any lover of Fluorite this is a amazing piece.

Serandite and Polylithonite with Aegirine
stock #19.1-257
Mont Saint-Hilaire, Monteregie
Quebec, Canada
2.8 x 2.6 x 1.3 CM (thumbnail)
price: $80

Multi-specie thumbnail from Mont Saint-Hilaire with a small blocky habit Serandite perched on top. The Serandite has a good orange color and is nicely set on a rosette of Polylithonite. This is a late 1960's vintage specimen.
