Koksha Valley, Badakhshan, Afghanistan
3.3 x 3.2 x 3.0 cm

MMB-703 - A pair of deep red, partially gemmy clinohumite crystals rests on just the right amount of matrix in this fine small miniature specimen. One crystal is doubly-terminated (the other almost) and both are sharply crystallized.





Calcite great luster Santa Eulalia Mexico small cabinet

Calcite - SOLD
Santa Eulalia Dist., Chihuahua, Mexico
7.3 x 7.1 x 4.6 cm

MMB-700 - Boasting great luster and complex crystallization, this fine quality calcite specimen has several isolated crystals (to 3.5cm) colored red with hematite inclusions. The larger crystals formed after an earlier growth of calcite rhombs, some colored by hematite, some clear, and some colored yellow by an unknown agent. Overall, the piece is all flash...very attractive and significantly better in person!

8.8 x 5.1 x 4.0 cm

MMB-698 - A cluster of wulfenite crystals (to 2.0cm) with color reminiscent of cream soda formed on a ridge of matrix in this superb specimen from Tsumeb.

12.1 x 4.1 x 3.2 cm

MMB-767 - Interlacing, fabric-like folds of matrix are completely covered by sea-foam green balls of adamite in this superb cabinet specimen from Greece. The mines in Laurium have been worked since Ancient Times, shaping the course of entire empires. Aside from its historical interest, this is just a lovely piece! Note that the color is richer than the photos indicate, without the white areas caused by the transparency of the adamite.

Newry, Maine, USA
5.0 x 4.6 x 4.0 cm


MMB-770 - Known primarily as an associated mineral found in pegmatites around the world, lepidolite can serve as an attractive specimen alone when reaching large crystal sizes and thicknesses.

Gersdorffite Bou Azzer Morocco fine crystal

Gersdorffite - SOLD
Aït Ahmane, Bou Azzer, Morocco
3.0 x 1.9 x 2.0 cm

MMB-765 - Rarely forming in octahedral crystals such as this, gersdorffite is a nickel arsenic sulfide (NiAsS--spelling correct here ???) usually found as cleaved masses or grains. The material is fragile and cleaves easily, thus fine specimens are difficult to acquire.

Calcite Stalactite - SOLD
Santa Eulalia, Chihuahua, Mexico
9.7 x 2.8 x 2.8 cm

MMP-2001 - Natural sculpture! A lustrous, complex calcite crystal faintly colored by hematite inclusions clings to a stalactite richly covered by an earlier generation of calcite.

Crystals of this quality are very difficult to replace, especially in today's market.

4.4 x 3.2 x 1.8 cm

MMB-737 - This ferro-axinite crystal not only shows quite a bit of transparency near the termination but also hails from the well-known American locality of New Melones Dam in California. And you thought only frogs were famous in Calaveras County! The specimen effortlessly shows its strong dichroism--clove brown and amethystine. The specimen is better in person than photos indicate.

6.7 x 6.0 x 5.5 cm

MMB-694 - Showing high luster and the transparency that has put this deposit on the map, this large cassiterite cluster would make a weighty addition to any collection of Chinese or world-wide minerals.
