Natural Dioptase on Copper-Rich Matrix – Rare Crystal Formation from Congo – Collector Mineral Specimen

This natural Dioptase specimen from Congo weighs 132 g and presents a rare combination of copper-rich rock with a few but remarkable crystals. Most of the piece is composed of solid matrix containing visible copper minerals, and on its surface grow several exceptional dioptase crystals. Tiny crystals, less than one millimeter wide, form a sparkling texture across the surface. Among them are two outstanding crystals of about 1 cm in diameter and another elongated crystal of 3 mm with perfect clarity and bright emerald-green color. The faceting and translucency of these few crystals make this piece truly unique and highly collectible. Origin: Katanga region, D.R.
