The round brilliant cut is one of the most popular because it allows the stone to sparkle in a most possible intensive way. It is a prism with ideal proportions, shape, and number of facets.

Like the round cut, the «Princess» cut is famous for its generous play of light in the stone, but it has a rectangular (less frequently square) shape. "Princess" is just as luminous as the round cut, which is why it is popular among engagement rings. Stones with lots of sparkling facets look great in single stone rings, earrings and pendants.

This cut is used in almost all kinds of jewelry: earrings, bracelets, necklaces and pendants.

However, the asscher cut is a more square version of this popular cut, not as elongated as the emerald cut. The number of facets varies depending on the weight of the stone. In terms of jewelry design, this cut is characteristic of Art Deco jewelry.
This cut is a hybrid of the old French square cut and the Emerald cut. A stone of this cutting style has the form of an octagon - a square or rectangle with cut corners. This cut is used for stones that have lots of things to show: rich color, clarity and transparency, the play of light and sufficiently large size.

The heart shape is also good for pendants and is sometimes used in earrings.

A cut in the form of an equilateral triangle with sharp or rounded edges. The Trillion facet stone has a very bright luster and fire when set at the proper depth that ensures its sparkle.
