ROUND CUT
The round, brilliantly cut diamond is by far the most popular and most researched diamond shape available today. For almost 100 years, diamond cutters have been using advanced theories of light behavior and precise mathematical calculations to optimize the fire and brilliance in a round diamond. In addition to being the most popular and researched shape, a round diamond will typically give you more flexibility in terms of balancing cut, color and clarity grades while still giving you the fire and brilliance you want.

ASSCHER CUT
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. If you choose SI-clarity, be sure to view the clarity plot on the diamond certificate, because this shape highlights the clarity of the diamond. When choosing a color grade, consider that while the price of a J-color non-round diamond is exceptional, color may be slightly visible in its corners.

CUSHION CUT
This unique shape has been popular for more than a century. Cushion cut diamonds (also known as "pillow-cut" diamonds) have rounded corners and larger facets to increase their brilliance. These larger facets highlight the diamond's clarity, so if you choose an SI clarity grade, be sure to review the clarity plot on the diamond certificate. Cushion cut diamonds are available in shapes ranging from square to rectangular. To find the dimension of cushion you want, look for the length-to-width ratio in our interactive diamond search and on each diamond's detail page. The length-to-width ratio will determine the diamond's outline, or what it will look like when viewed from the top.

EMERALD CUT
What makes this shape unique 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. If you choose an emerald cut with a lower clarity grade, such as SI, be sure to review the clarity plot on the diamond certificate. Also, emerald cut diamonds can vary greatly in how rectangular they are. If you'd prefer an emerald cut with a squared outline, look for an Asscher-cut diamond.
