Dioptase is named after Greek word for "view through" referring to the mineral's two cleavage directions that are visible inside unbroken crystals.
Dioptase is a popular collectors' mineral specimen and is smetimes cut into small emerald-like gems. The material is very soft to be worn as a ring-stone, but small specimens are sometimes mounted in pendants and brooches.
