A remarkably unusual piece with starkly isolated crystals of dioptase, perched on quartz! The razor-sharp, pristine, major dioptase crystals reach 1.9 cm, fairly good size from any locality. While not gemmy, they are quite translucent. The smaller crystals to the lower left are also compete, though show some minor contacting. This is a unique style of combination, not similar to material yet found at other dioptase lcoalities in the isolation upon crystalline quartz matrix
