Dioptase Specimen - Congo

Dioptase Specimen – Congo (Tantara Mine, Shinkolobwe, Katanga)

Specimen weight: 167g

Intense emerald-green dioptase crystals with vitreous luster and sharp rhombohedral terminations, mounted on a distinctive brown quartzite matrix devoid of significant associated minerals. Crystals exhibit high clarity and deep color saturation attributed to copper silicate composition. Prized for sculptural forms and pure dioptase concentration, reflecting the unique geology of Katanga's oxidation zones.
