J920 - Copper $ 750 (=~ € 685) Ajo, Arizona, USA large cabinet - 32 x 13.5 x 1.2 cm Large Ajo Copper with a row of tall crystals to 13cm. The crystals formed in a seam and the specimen has a uniform thickness it's entire length. This was in an old collection I bought and based on the other minerals in the collection, I estimate it's from the 1970s or 1980s. Reminds me of an old saw blade.
J777 - Cuprite on Copper $ 200 (=~ € 183) unknown miniature - 5 x 4.5 x 3.7 cm Octahedral Cuprite crystals covering Copper. Out and collection with no locality given, and therefore priced low.

Hutchinsonite is a rare thallium sulfosalt species and these recently found red crystals are some of the best ever found. Crystals reach 8mm long and contrast nicely with the Pyrite. Undamaged with an even distribution of both species across the front face. About as nice a Hutchinsonite specimen as you could expect and the best one I've ever had.

Found in 2008 by Bob Barron while metal detecting the lake floor of Lake Superior in about 15 feet of water off Eagle Harbor.

D152 - Prehnite $ 1800 (=~ € 1645) Merelani Hills, Arusha, Tanzania cabinet - 12.5 x 7.5 x 6 cm Large, catepillar-like formation of Prehnite crystals. A very interesting specimen for it's unique form, distinct crystals, and coloration (way better than photos - the camera didn't pick up the blue green color well). New finds at Merelani have produced Prehnites with a color I've not seen before, sort of a mixture of both green and blue. This specimen features both typical lemon yellow and the new blue/green colored crystals. While most Prehnites from other parts of the world occur as botryoidal masses or spheres, Merelani produces well formed, distinct crystals, and this specimen is loaded wtih them. It has double-terminated clusters to 5cm and individual crystals to 3cm. There is one small smooth area where it contacted a Calcite crystal, otherwise it's a floater covered by crystals on all sides, with little if any damage. One of the best, if not the best, Merelani Prehnite I've had. Minor Pyrite and Graphite in association.
