All auctions / Ethnographic / RARE BRILLIANT BLACK DIAMOND – 0.92 ct – India NO RESERVE...


This specimen is a unique rough diamond from India, with a compact and angular morphology typical of natural black diamonds. The stone is distinguished by a dominant black hue, enhanced by steel-gray and silvery reflections visible on the reliefs under lighting. Its appearance is opaque, with a diffuse adamantine luster generated by a multitude of natural micro-facets. The irregular and granular texture reflects a polycrystalline formation, resulting from extreme geological conditions deep underground.

Fragmented adamantine luster: The natural surfaces reflect light diffusely, creating discreet metallic glints.
