Rough-cut diamonds, also known as raw or uncut diamonds, are diamonds that have not been polished or shaped after being extracted from the earth. These diamonds are in their natural, unrefined state, which means they retain their original crystal form and often display a unique, rugged appearance.

This refers to the presence of inclusions or blemishes within the rough diamond. Clarity grades range from flawless to included, affecting the diamond’s overall value.
Colour
Rough diamonds come in a spectrum of colours, from colourless to fancy colours like yellow, pink, blue, and green. The colour grade significantly impacts the diamond’s desirability and price.
Quality
The overall quality of a rough diamond is assessed based on its potential to produce high-quality polished gems. This includes evaluating the stone’s internal structure and potential yield.
