The first dioptases arrived in the West from the Kyrgyz steppes. Its first study took place in the late 18th century on Kazakhstan mine specimens. German mineralogist Moritz Rudolph Ferber was the first to study this mineral closely. However, he misclassified it as an emerald stone due to its emerald green. In 1797, French mineralogist René Just Haüy noted that it was a separate mineral upon studying its chemical composition. He gave it the name dioptase, from the Greek dia meaning ‘through’ and optos meaning ‘visible’, in reference to the fact that one can see traces of cleavage planes through the stone’s crystals.
Dioptase belongs to the silicate family. It is part of the Rhombohedral crystal system. Dioptase has a chemical characteristic composed of copper silicate hydrate. It is made up of crystals in the form of prisms that are transparent or translucent, with a vitreous lustre and a green stripe. Emerald green that can range to dark blue-green, its size varies depending on whether it comes from Tsumeb in Namibia or the Democratic Republic of the Congo. It is a rare stone found on land with copper deposit oxidation zones. It is very often associated with other minerals such as Chrysocolla, quartz or wulfenite.
The best deposits that provide quality stone are located in the Democratic Republic of the Congo where crystals of exceptional quality and dimensions of up to eight by two centimetres cover chrysocolla geodes. Wonderful specimens can be found on white calcite in Tsumeb, Namibia, or on quartz in Kaokoland. The Tsumeb Gallery exhibits beautiful photos of this stone. In addition, photos can be viewed at the Renéville gallery. The largest known specimens exceed fifteen centimetres in length and come from Angola. Beautiful stones can also be seen in Kazakhstan and several mines in the Arizona region such as the Mammoth-Saint Anthony mine, where it is sometimes associated with wulfenite.
