Almost a complete floater, this acanthite specimen can be displayed on either side to equal effect. It is very 3-dimensional and treelike, and just sharper than most acanthites from here tend to be. The dark gray crystals are arborescent, with a few exhibiting incipient, hopper growth. The largest crystal is 1.1 cm in length. Some crystals have a thin coating of brassy yellow chalcopyrite, as well as the base of the cluster. Any way one views this specimen, it is really a fine example for the size and locale! MUCH BETTER In PERSON. Comes with custom lucite base already made for the specimen.
