This specimen consists of at least two dozen stubby, prismatic crystals of dioptase with a minor amount of calcite on a light colored matrix. These dioptase crystals show excellent form, and range in size to a little over 0.1" (0.3cm). Under magnification, the crystals are seen to be translucent. The damage on this specimen occurs primarily on the sides where it was broken away from the host material-the crystals in the center of the specimen are pristine.
