Round

The round brilliant cut diamond is by far the most popular and most researched diamond shape available today. This classic shape is the choice of many for their engagement rings. Diamond cutters have been using advanced theories of light behavior and precise mathematical calculations to optimize the fire and brilliance in a round diamond. A round diamond will typically give you more flexibility in terms of balancing cut, color, and clarity grades while still getting the fire and brilliance you want.

Princess

A relatively new cut, its beautiful brilliance and unique cut makes it a favorite for engagement rings. The princess has pointed corners and is traditionally square in shape. Also, princess-cut diamonds can vary greatly in how square or rectangular they are. For a princess diamond shape that is square, look for length-to-width ratios between 1 and 1.05. If you prefer more of a rectangular shape, look for length-to-width ratios greater than 1.10. For the most brilliant princess available, feel free to contact one of our Diamond Specialists.

Emerald

What makes this shape different is its pavilion, which is cut with rectangular facets to create a unique optical appearance. Due to its larger, open table, this shape highlights the clarity of a diamond. Emerald-cut diamonds can vary greatly in how rectangular they are.

Asscher

This beautifully unique shape is nearly identical to the emerald-cut, except that it is square. Also, this shape has a pavilion that is cut with rectangular facets in the same style as the emerald-cut.

Marquise

The shape of a marquise diamond is that of an elongated diamond with pointed ends. Marquise shape can maximize carat weight, giving you a much larger-looking diamond. This brilliant-cut diamond looks beautiful set with round or pear-shaped side stones, and the length of the marquise makes fingers appear long and slender. For the most traditional marquise-cut diamonds, look for length-to-width ratios between 1.75 and 2.25.

Oval

With even symmetry and beautiful brilliance that's similar to a round diamond, Oval diamonds are also very popular as their length can accentuate long, slender fingers. For the most traditional oval diamonds, look for length-to-width ratios between 1.33 and 1.66.

Radiant

Pear

A Pear is also called a teardrop for its single point and rounded end. The unique look of the pear shape helps make it a popular choice especially for pendants and earrings. For the most traditional pear-shaped diamond, look for a length-to-width ratio between 1.45 and 1.75.

Heart

Cushion

This unique shape was borne out of the ‘old mine’ cut and has been popular for more than a century. Cushion-cut have rounded corners and larger facets to increase their brilliance. These larger facets highlight the diamond's clarity, so lower clarity grades with obvious inclusions will show up more obviously.
