Dioptase is one of the most sought-after secondary copper minerals, renowned for its intense emerald-green colour and exceptional vitreous lustre. Although its colour rivals that of emerald, it owes its rich green hue to copper and forms naturally in the oxidised zones of copper deposits, where it develops into beautifully terminated rhombohedral crystals.

The Kimbedi deposits have earned an international reputation for producing world-class dioptase specimens prized by collectors for their colour, crystal quality and natural aesthetics. This specimen displays a dense cluster of well-formed crystals across its matrix, creating an attractive miniature that captures the distinctive character of this famous locality.

Whether you're expanding a Congo mineral collection, adding an outstanding copper mineral to your display cabinet, or searching for a unique gift for a mineral enthusiast, this Dioptase Crystal Cluster is an authentic collector's specimen that showcases the remarkable beauty of natural crystal growth.
