- Acanthite Ps. Argentite
- Imiter Mine, Atlas Mountains, Quarzazate Province, Morocco
- Small Cabinet, 6.1 x 4.6 x 4.3 cm
This specimen of acanthite after argentite features a series of stacked, octahedral, splendent, jet-black crystals, to 1.8 cm in length. the crystals literally leap out from a matrix of calcite, silver ore, and massive acanthite (few specimens have any matrix, here). This new find has luster - bright sparkling luster that is hard to convey in photos and quite another world from the appearance of previous finds here. I particularly like the angled group at the top of the specimen, which features a birdlike crystal cluster of 2.4 cm atop. This is a superb, elegant acanthite by any standard, quite different from Mexican and Chinese and German acanthites we might have seen previously.
