Girdle The middle section of a diamond or gemstone, which can be polished or faceted on a diamond, and typically unpolished on color gemstones.

Hardness The ability of a diamond or gemstone to resist scratches, which is measured using the Moh’s scale of hardness from 1-10, with 10 being the hardest.
