This really is the finest specimen in the lot for my taste. The piece has an extremely large, very sharp, incredibly lustrous, showy, well-formed, highly aesthetic crystal group perched upon a microcrystalline Quartz matrix. This "cabinet" size specimen is one the finest matrix Bournonite specimens that I have seen from Bolivia.(Crystal Group: 5.5 x 3 cm. across)
