The name “dioptase” come from the Greek words for “to see” and “through” and references the visibility of cleavage plains within the translucent, brilliantly emerald green crystals of this copper cyclosilicate mineral. This specimen boasts incredibly lustrous and deeply-hued crystals accompanied by just a sprinkling of matrix. The cube in the picture is one centimeter.
