diamond glossary, BarninkaDiamond Term Explanation

  1. A diamond can be 'coated', ie. colored by a surface coating which masks the true body color; the coating may be extensive (entire pavilion, for example), but is more often limited to one or two pavilion facets or a spot on the girdle.
  2. Grading 'color' in the normal color scale range involves deciding how closely a diamond's body color approaches colorlessness or white. Most diamonds have at least a trace of yellow -off white - body color. With the exception of some natural fancy colors, such as green, canary, blue, pink, purple, or red, the colorless white grade (D+ or River+) is the most valuable.
  3. The upper part of the diamond above the girdle. Consists of a large flat area on top called a table, and several facets below it.
  4. The smallest facet at the bottom of the diamond.
  5. The proportions and finish of a polished diamond (also called make). 'Cut' can also mean shape, as in emerald cut or marquise cut. Proportions are the size and angle relationships between the facets and different parts of the diamond. Finish includes polish and details of facet shape and placement. 'Cut' affects both the weight yield from rough and the optical efficiency of the polished diamond; the more successful the cutter is in balancing these considerations, the more valuable the diamond will be.
  6. CZ, a widely used simulant, an imitation for a natural diamond.
