Dioptase is prized for its vibrant emerald-green colour and exceptional crystal brilliance. It forms in the oxidised zones of copper deposits, where silica-rich fluids react with copper minerals to produce its distinctive transparent to translucent crystals. Its intense colour and limited occurrence have made it one of the world's most sought-after secondary copper minerals.
Collected from the renowned Kimbedi deposit, this Dioptase from Congo is a beautiful natural specimen that showcases the exceptional crystal quality for which this locality is internationally recognised.
