A sprinkling of striking green Dioptase crystals embedded within a Calcite matrix. The rare mineral specimen has been hot-glued to an acrylic base, but can easily be removed by carefully running hot water along the base. Please do not submerge specimen in water.
Measurements (with stand): ~2" tall x 2-1/2" wide x 1-1/4" deep
Location: Sanda, Kimbedi, D.R.O.C
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).
