M483 - Copper $ 450 Ajo, Pima Co., Arizona, USA cabinet - 13 x 8 x 3.5 cm ![]() ![]() ![]() ![]() ![]() ![]() Large, heavy mass of Copper crystals. Individual crystals reach 1.5cm in size.
M761 - Prehnite after Anhydrite $ 240 Prospect Park Quarry, Prospect Park, Passaic Co., New Jersey, USA small cabinet - 6 x 6 x 2.5 cm ![]() ![]() ![]() ![]() Translucent apple green Prehnite cast that formed over a flat, tabular Anhydrite that then dissolved away leaving this hollow cast. Botryoidal, translucent Prehnite forms over the front and back with the shape of the former Anhyrite easily seen when looking up from the opening in the bottom. A wonderful example from long ago, and not as jumbled as some larger pieces are - this is a nice distinct cast of a single large crystal.
M598 - Rhodochrosite with Fluorite $ 600 Sunnyside Mine, Silverton, San Juan Co. Colorado, USA small cabinet - 7.5 x 6 x 4.5 cm ![]() ![]() ![]() ![]() Pale blueish green Fluorite crystals with pink Rhodochrosite from a classic Colorado locality, on a Quartz and sulfide rich matrix.
M511 - Copper $ 400 Keweenaw Peninsula, Michigan, USA cabinet - 15 x 9 x 7.5 cm ![]() ![]() ![]() ![]() ![]() Large hackly mass of Copper from the famous Copper mining area of Michigan. Weighs about 2.5 pounds. The nice thing about this piece, besides it's size, is that alot of the weight is towards the bottom and it stands up on it's own perfectly for display and is very stable.
M832 - Chalcoalumite $ 220 Grandview Mine, Grand Canyon, Coconino Co., Arizona, USA miniature - 5 x 3.5 x 2.5 cm ![]() ![]() ![]() ![]() Bright Robin's egg blue Chalcoalumite covering matrix. These specimens are very hard to come by now as the locality is now part of a national park. This old copper mine began operation in 1892, stopped operation around 1907, and became a part of the national park in 1940. The specimen is likely over 100 years old! From an old collection and comes mounted in a plastic box.

M888 - Ilvaite $ 180 Huanggang Mine, Inner Mongolia, China miniature - 4.5 x 2.2 x 2.2 cm ![]() ![]() ![]() Thick, glossy single black Ilvaite crystal with typical chisel-shaped termination. There is a small area of Quartz in one termination face that has caused an indentation in the face. I'm not sure if it natural growth or damage as the Quartz itself is fully crystallized. Complete all around. Good large, thick crystal.
M906 - Chrysoberyl $ 225 Minas Gerais, Brazil thumbnail - 1.5 x 1.1 x 1 cm ![]() ![]() ![]() ![]() Small sixling twin of Chrysoberyl. Although the top two are larger, all six 'legs' are present. Transluscent and undamaged.

Glassy luster and gemmy with very slight surface etching. I found one tiny, trivial nick, otherwise complete all around and undamaged.
M913 - Tourmaline $ 2000 Paprok, Kamdesh District, Nuristan, Afghanistan small cabinet - 5.5 x 2.2 x 1.5 cm ![]() ![]() ![]() ![]() ![]() Highly aesthetic cluster of 4 intergrown Tourmaline crystals with alternating colors of green and red. Interestingly, the taller crystals have more typical terminations and the shortest crystals has a more flat termination face. Undamaged.

M921 - Spessartine, Apatite $ 625 Shigar Valley, Skardu, Pakistan thumbnail - 3 x 2.5 x 2.5 cm ![]() ![]() ![]() ![]() ![]() ![]() Red Spessartine either grown over or replacing a pink Apatite crystal. The garnets come together around the Apatite and retain the general form of the Apatite, with natural gaps between the garnets evidenced by etched faces in the walls of the gaps. These are certainly unusual and uncommon specimens, and I've only had 2 before. A flaoter fully crystallized all around, with attached mica.
