2" Sparkling Dioptase Crystal on Quartz - Sanda, Congo

This is a beautiful dioptase crystal on quartz, collected from the Sanda Hills occurrences (Sanda mine) in the Republic of the Congo. This mine has been closed since 2019, so this material is old stock. The entire specimen is 2" wide and the dioptase is an alluring emerald-green color.

It has been mounted to an acrylic display base with mineral tack.

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 centimeters in length. It is popular with mineral collectors due to its vibrant color and it is occasionally cut into small emerald-like gems.
