A large specimen featuring a very sturdy 4 cm cluster of stout silver crystals perched as if on the side of a mountain, with pretty good aesthetics as far as these go. The silver has completely replaced the earlier Dyscrasite. Most such specimens are without matrix, and thus this is somewhat special in that it displays so nicely the cluster on matrix. Ex.
