1.8" Sparkling Dioptase Crystal Cluster - N'tola Mine, Congo

This is a beautiful cluster of sparkling dioptase crystals that was collected from the N'tola Mine of the Republic of the Congo. This mine has been closed since 2019, so this material is old stock. The entire specimen is 1.8" wide and the dioptase is a lustrous, emerald-green color.

Dioptase is an uncommon mineral found mostly in desert regions where it forms as a secondary mineral in the oxidized zone of copper sulfide mineral deposits. This copper based mineral forms small rhombohedral crystals, typically less than 0.75 cm in length.
It is popular with mineral collectors due to its vibrant color and it is occasionally cut into small emerald-like gems.
