High Quality Dioptase Specimen from Congo – 294 grams (with base)

An exceptional dioptase specimen featuring vivid, saturated emerald-green crystals with outstanding brilliance and translucency. The crystal faces are sharp and highly reflective, creating a sparkling, almost glass-like appearance across the entire surface. There are also tiny little quartz crystals growing on the dioptase. 

The dioptase forms a dense, drusy coating over natural matrix, with numerous well-defined crystals that catch and reflect light beautifully. The color is intensely rich and vibrant—classic for fine dioptase—with a depth that is difficult to fully capture in photographs.

This piece comes from an older collection and is mounted on a display base, which it will remain attached when sent. When you receive it you can decide whether you want to remove or keep attached. 

A high-end display specimen with remarkable color and luster, ideal for collectors seeking top-quality dioptase.
