	Brilliant Cut / Round The most popular diamond shape is currently the round-brilliant cut. This diamond cut is optically brilliant diamond because of its 360-degree symmetrical shape.

This stone shape also works well with nearly all mounting types including four prong, six prong, channel, bezel, half-bezel and illusion.

Due to its larger, open table, this diamond shape showcases the clarity of a diamond the best. The blocked corners are usually cut to a rectangular outline, but can be cut in a square shape. Since they can vary greatly in how rectangular they are and your preference is for an emerald cut with a squared outline, look instead at the Asscher-cut diamond.

	Heart The ultimate expression of romance and love, the heart shaped diamond is cut with triangular and kite-shaped facets which reflect light.

	Oval The oval cut has beautiful brilliance very similar to a round-brilliant cut. An oval shape combines the sparkle of the round shapes with a finger flattering, elongated outline. It makes a good choice for someone who wants something more unique but still wants the fire and brilliance of a round cut diamond. The relatively symmetrical shape lends itself well to a variety of mounting styles. Most oval cuts work in a mounting with six prongs properly spaced for security.

	Pear The less common but visually interesting pear shaped diamond is a unique variation of the round diamond cut. there are generally 58 facets which allow the light to pass through it just as well as the round diamond cut. It is a popular choice for many solitaire diamond engagement rings or diamond rings with side stones.

	Princess The princess cut is the 2nd most popular diamond shape because of its modern classic shape offering clean lines and immense sparkle. A princess cut has either a square rectangular appearance depending on the way it was cut. The cutting process utilizes the step-cutting of the emerald cut with the triangular facets of the brilliant cut. Princess cuts will work best in a prong or channel setting.

	Radiant The distinctive trimmed corners give a radiant cut its beautiful appeal. This diamond shape combines a square or rectangular shape with the brilliance of the traditional round cut. It combines the Round Cut style and the Emerald Cut style to make a non-traditional diamond. A radiant cut looks great in a solitaire setting or when prong set with side stones.
