- Natural
- A trade term for a portion of the original surface of a rough diamond that is usually left by the cutter on a fashioned stone, usually on the girdle. The excuse for leaving naturals is to show that there was no unnecessary weight loss in the rounding-up and polishing operations. The American Gem Society considers that naturals that do not flatten the girdle outline nor extend beyond the width of a medium girdle should not be regarded as blemishes.
- Nick
- A minor chip out of the surface of a fashioned diamond, usually caused by a light blow. It is more likely to be found along the girdle than elsewhere, although it may also appear on a facet junction or on a facet.
