The Round Brilliant Cut

Round brilliants are by far the world’s most popular cut. Here are a few facts about the round brilliant cut:

  • Round brilliants have either 57 or 58 facets
  • If the diamond cutter chooses to add a culet facet (a cut on the bottom of the diamond) the stone will have 58 facets
  • Each individual tier of facets can be cut on the same angle which enhances the “optical efficiency” of the diamond
