Modern Round Brilliant Cut which is the most common diamond cut, has 58 facets.

Performed by a jeweler by the name of Harris, this cut is the culmination of a technique possibly invented in Venice in the early seventeenth century: the brilliant cut.

A color stone (1) is formed of a material having a refractive index n of 1.55 to 2.40 and has been subjected to round brilliant cutting.

The round brilliant cut is the most popular diamond shape, accounting for more than half of all diamonds sold today.
