Diamond Cut

The only things humans can do to a diamond to affect its value is to cut it.

The color, clarity and carat size of a diamond is determined by nature, but only when a diamond is cut is its brilliance and beauty truly exposed.

An uncut or rough diamond, in many senses, looks a lot like any other stone. It's only when the stone is shaped and cut, when the facets are created, that the diamond reveals its ability to play with light and reward the viewer with a dazzling display of brilliance and fire. When the facets, or faces, are created, the diamond goes from a unremarkable stone to an object of extreme beauty.

There are many traditional cuts for diamonds, none more popular than Round Brilliant. These diamonds, when viewed from the top, are round, but contain 58 total facets, 33 on the crown or upper part, and 25 on the pavilion or bottom part. This cut is elegant and is the standard cut of diamond. Other basic cuts are Emerald, Princess, Heart, Oval, Marquise, and Pear.
