Mineral Specimen

Most gem material must be cut and polished before it reveals its full beauty. But from time to time we find rough stone that is intrinsically beautiful in its natural form. These rare specimens display fine color, luster and transparency without human intervention, and they also exemplify characteristics of crystal growth typical of the particular species.
