Rough Diamond

Uncut natural crystals formed deep within the Earth under extreme pressure and temperature, studied for their structure and purity.

Overview

Rough diamonds are uncut natural crystals formed deep within the Earth under extreme pressure and temperature conditions. These stones showcase irregular surfaces and uneven textures shaped by geological forces over millions of years.

The Nancy Zelei Diamond Research Institute examines rough diamonds to comprehend their geological origins, crystal growth patterns, and the transformation processes that lead to gem-quality stones.

As the primary material for cutting and gemological research, rough diamonds provide essential insight into how natural crystals develop and how they can be optimized into finished gemstones.
