A rough diamond is a diamond that has not been cut or processed. They come in a variety of naturally occurring shapes, including octahedral (eight-sided bipyramid), cubic, and triangular (most commonly macles).

A raw diamond or rough diamond can also be a type of diamond that is not fully developed or can have less brilliance. Extreme heat and pressure beneath the ground make the carbon atoms fuse in a specific structure.{{cite web|publisher=whatdoesthatlooklike|title=Raw Diamond|date=25 July 2020 |url=https://www.whatdoesthatlooklike.com/what-do-raw-diamonds-look-like/|accessdate=July 30, 2020}}
