The Dioptase with Malachite & Chrysocolla Specimen (Congo) – 刚果翠铜矿共生孔雀石与蓝铜矿矿标 is a beautiful natural copper-mineral association showcasing three visually distinctive minerals in one specimen.
The star of the specimen is Dioptase, recognised for its exceptionally vivid emerald-green colour and glassy lustre. It occurs naturally alongside Malachite, with its characteristic rich green tones and banded or earthy textures, as well as Chrysocolla, which contributes beautiful blue, turquoise and blue-green colours.
The combination creates a remarkable spectrum of natural copper-mineral colours, ranging from bright emerald green through deep green to turquoise blue.
Congo is particularly well known for its copper-rich mineral deposits and has produced many highly attractive specimens featuring Dioptase, Malachite and Chrysocolla.
Every specimen is naturally unique, with variations in crystal formation, colour distribution, matrix and mineral association.
