List of Stones & Minerals

Dioptase is a mineral species, from the group of silicates, subgroup of cyclosilicates. Its chemical formula is CuSiO3·H2O. It was the German scientist Rudolph Ferber who, at the end of the 18th century, first became interested in dioptase. He incorrectly defines it as an emerald. But it was the French abbot René Just Haüy who discovered that it was a separate mineral. He gave it the name dioptase in 1801, deriving from the Greek dia (“through”) and optazo (“I see”), since traces of cleavage planes can be seen through crystals.
