The name “dioptase” comes from Greek and references the visibility of the twin cleavage plains within the startlingly translucent, brilliantly emerald green crystals of this rare copper cyclosilicate mineral. This specimen boasts a thick, glistening coating of beautifully gemmy dioptase crystals covering the face of the matrix.
