Diamonds are cut in a variety of shapes with a single focus : to preserve and maximize carat weight. Since rough diamonds can come in unpredictable shapes and sizes, the diamond cutter will create whichever shape maximizes carat weight and value.
Round cut diamonds result in the most wastage of rough diamond carat. The other fancy shapes are deeper and tend to have longer, less uniform shaping so they capture more of the rough diamond.
Diamond value is often in part by the amount of wastage in the rough diamond when cutting a particular diamond shape. Shapes that save more of the rough diamond can be less expensive. Popularity and availability are the other factors that determine the price of the diamond.

This diamond cut is perfect to display classy, elegant, and timeless look. Today most round diamonds are cut in the brilliant style. This means that they have more facets and angles.

The origins of the cushion cut diamond dates back to the 19th century. While similar to the princess cut, it features a relatively square shape. However, the cushion cut is special in the fact that it can come in many ratios, making it either square or rectangular with rounded corners.
Cushion cuts blend sparkle of a round brilliant with the symmetry of a radiant cut. It’s appeal is reflected in its larger 58 facets and rounded, squared corners. Also known as the “pillow cut,” the cushion cut has larger faceting, which augments the diamond’s brilliance.
Larger facets can show clarity inclusions, so evaluate the location of inclusions by examining its certificate.

Emerald diamond cuts were some of the very first diamond cuts in the world. This cut is perfect for colored gemstones as well as high-quality diamonds; if choosing an emerald cut, it is recommended not to compromise in diamond quality because the style emphasizes the color in the stone.
Emerald diamond cut represents unification, being well proportioned and bringing out the pure brilliance of a diamond. Also known as “step cut” because of the layered faceting, the emerald cut possesses unique appeal with symmetrical sparkle. The faceting is minimal and simple, and therefore tends to show inclusions. The diamond has 58 facets, roughly 25 on the crown, 25 on the pavilion, and 8 on the girdle with 3 rows of bottom steps and three rows of top steps. An open setting can also show the diamond’s color, so closed or bezel type settings are recommended with lower colors.
Originally invented by Henry Grossbard in 1977, to combine the best aspects of the round cut with the best aspects of the emerald cut. The radiant cut diamond is considered to be one of the shiniest cuts of diamonds because of its 70-facet cut.
A beautifully symmetrical, non-traditional cut, the radiant cut combines the brilliance of a round and the purity of an emerald cut. Trimmed corners give it versatility among all kinds of jewelry, especially engagement rings. The faceting of a radiant cut gives it a fiery look compared to a princess cut, while maintaining soft, cut corners.
The radiant fuses the plus points of other popular diamond shapes. The rectangular radiant cut is an excellent option for buyers who like the emerald cut shape, but want something with the brilliance of a round. A ratio of 1.00 to 1.05 will create a square shape, and from 1.30 to 1.50 will produce a rectangle.
Originally developed in 1902 this cut is nearly octagonal in shape due to all of its curved edges. Asscher cuts give off a timeless effect with their vintage and unique designs. Asscher cut diamonds create more of a soft glow emanating from the stone than a brilliant statement piece.
The asscher cut is (also a step cut diamond like the emerald cut) is a blend of the princess and emerald cuts with X-shaped facets from its corners to its center culet. The brilliance of its faceting can mask certain inclusions and lower color grades. Asscher cut diamonds have a clean balance, visual appeal, and can reflect clarity inclusions and color. Higher grades in both categories are generally recommended. The step cut emphasizes the clarity of the diamond, and it is ideal for showcasing higher clarity diamonds. Suggested Cut Ratio: 1.00 to 1.05 for square proportions.
