Its specific gravity is 3.28–3.35. And it has two perfect and one very good cleavage directions. Additionally, The mineral is very fragile. Some specimens must be handled with great care. It is a trigonal mineral. It forms in 6side crystals. They have rhombohedral terminations.
At the end of the eighteenth century, the German mineralogist Moritz Rudolph Ferber first became interested in this mineral. But he defines it erroneously as an emerald. And it was the French mineralogist René Just Haüy who, in 1797, proved that it was a mineral by itself and gave it the name dioptase.
The name comes from the Greek dia (” Through “) and optazo (” I see “). It refers to the fact that the traces of the cleavage planes can be visible through its crystals.
