A well developed crystal cluster of beautiful green Dioptase. There are a few larger, terminated crystals surrounded by smaller crystals. The specimen will be sold with a stand as shown in the photo.
Measurements (without stand): ~1-5/8" wide x 2" tall x 1" deep
Location: Karagandy Province, Kazakhstan
Dioptase crystals are emerald green and translucent. The mineral got its name from the Greek words for "to see" and "through" because of the ability to see internal cleavage planes of the small crystals. The mineral forms in rhombohedral crystals (usually less than 1cm in size) with a chemical composition of CuSiO3 (H2O).
