Diamond shape is the outline and form of a diamond after it has been cut & polished.
Round Cut Diamonds
Round diamonds, the most popular shape, have received more attention from gemologists than any other variation. This shape is known for its unrivaled fire and brilliance, as well as its excellent light refraction properties. When all other factors are equal, round cut diamonds are more valuable than other shapes.
Princess Cut Diamonds
The princess shape, a square stone with 90-degree corners, was invented in the United States in 1980. Princess diamonds that are perfectly square in shape are the most valuable, with more rectangular variations decreasing in value.
Asscher Cut Diamonds
This diamond shape was introduced in 1902 by renowned diamond cutter Joseph Asscher and employs many of the same cutting techniques as the emerald cut. Asscher diamonds are distinguished by their distinctively angled and cropped corners, which create a timeless look.
Radiant Cut Diamonds
Radiant diamonds, which are relatively new to the jewelry industry, were introduced a little more than 20 years ago. This one-of-a-kind shape combines a traditional round cut with an elegant emerald cut, resulting in a square, near-square, or rectangular orientation. Radiant diamonds, as the name implies, emit a beautiful, memorable glow.
Cushion Cut Diamonds
The cushion cut diamond has a rich diamond history, having first appeared in the jewelry market in the early 1800s. Many consider it to be a more vintage version of the round cut diamond, cut into a square or rectangular shape with rounded corners and sides.
Emerald Cut Diamonds
Emerald cut diamonds are usually rectangular in shape. Distinguished by beveled corners and step facets, this type of diamond is more transparent than other shapes, often requiring higher standards of clarity.
Marquise Cut Diamonds
The marquise cut is rumored to have been specially developed for King Louis XIV of France who wanted a diamond that simulated the smile of Marquise de Pompadour. The elongated Marquise stone has gracefully pointed ends for a dramatically beautiful appeal.
Oval Cut Diamonds
An oval diamond with the same number of facets as a round diamond has nearly the same level of brilliance and fire. Because of its elongated shape, the oval cut can appear larger than an equal-carat round diamond (weight).
Pear Cut Diamonds
The pear shape diamond (also known as a drop cut or teardrop diamond) exudes elegance and is cut to resemble a drop of water with a single point and rounded end. As a result, the shape is a cross between a round and a marquise cut.
Heart Cut Diamonds
The heart cut diamond, true to its name, has become synonymous with love and affection, making it an excellent choice for an anniversary or engagement ring. A heart-shaped stone is one of the most difficult diamond cuts to create, requiring great skill and dexterity from the diamond cutter.
