    • n bort A collective name for diamonds of inferior quality, especially such as have a radiating crystallization, so that they will not take a polish. These are crushed to form diamond-powder or diamond-dust, which is used for cutting and polishing diamonds and other precious stones.
    • n bort An amorphous variety of diamond, brown, gray, or black in color, and known also as black diamond or carbonado, found massive in Brazil in association with pure diamonds. This is extensively used as the cutting material in diamond drills and stone-saws, for which ordinary diamonds are unsuited from their crumbling and cleaving.
