Scintillating, very gemmy, emerald-green dioptase crystals richly cover both sides of the sculptural, triangular matrix covered with starkly contrasting white calcite rhombs. Dioptase on calcite is a highly desirable combination from this mine. This is a highly representative example of the species and renowned locale, and the dioptase crystals are really far above average, in gemminess and color, for the locale.
