Available Shapes for Lab Diamonds

Ada Diamonds offers diamonds in ten gemstone shapes, and no shape is superior to another. Whether you’re interested in a brilliant cut with its triangular facets that capture and reflect the most amount of light, or a step cut with its hall of mirrors effect Ada Diamonds guarantees that its diamonds are among the best cut in the industry.

Here is a printable sizing chart that allows you to see the true size of various carat weight diamonds of various shapes.

Round

Circular in shape, and brilliant in style. This classic cut is the most popular diamond style of the last 100 years. The round brilliant has 58 facets, and its proportions maximize the potential fire and brilliance.

Oval

Oval cut diamonds were popularized in the 1960s, and are often said to make the finger of the wearer appear more elongated given its shape. Since oval diamonds vary in width, you can work with our Diamond Concierge to find the dimensions that work best for your design.

Pear

The pear cut diamond is a combination of the round brilliant and marquise shapes, resembling the shape of a teardrop. As it was first created over 500 years ago, the pear cut is one of the oldest diamond cuts in the market.

Cushion

The cushion cut may show patterning similar to a round brilliant or more of a crushed ice appearance. The shape features rounded edges and a slightly elongated LW ratio.

Princess

The Princess cut—also known as the Square brilliant—has the brilliance and fire of the Round Brilliant, but it is square in shape. This cut was perfected in 1979 by Israel Itzkowitz.

Radiant

The Radiant Cut is octagonal in shape with clipped or cut corners, which make the gemstone easier to set in jewelry and more durable. Radiants can also be cut in either rectangular or square dimensions. This cut is also known as a Cut Corner Square Brilliant or Cut Corner Rectangular Brilliant.

Emerald

One of the oldest diamond cuts, it features large facets and cropped corners that draw light into the center of the stone, intensifying its brilliance and fire. Rectangular in shape, the emerald cut is a beautiful choice for Ada’s best diamonds.

Asscher

The asscher cut is similar to the Emerald cut, but is square in shape and more closely resembles an octagon. This cut is named in honor of Joseph Asscher, who perfected the emerald and asscher cuts in the late 19th century. Given their geometric symmetry, it makes sense that they would have been a staple in art-deco jewelry.
