Most popular diamond cut : Round diamonds

Round diamonds

As the most popular choice and most known shape, round diamonds make up the vast majority of the supply.

Generally used in rings and solitaire sets, these diamonds generally require a four pronged setting and can add immense shine and brilliance to a particular piece of jewelry. 

The round cut diamond is also known as the brilliant cut. The modern round brilliant consists of 58 facets (or 57 if the culet is excluded.

Princess diamonds

Princess diamonds

Only introduced in the 1980's, the princess cut diamond has quickly gained in popularity and is today the second most sought after shape. One of the advantages of the princess cut is that existing inclusions are less visible thanks to the unique cutting and polishing techniques. The downside of the cut is that it also brings out color more clearly. In addition when cutting a princess shape there is less rough diamond lost, in fact more than 60% of the original stone's weight is utilized.

But there is one precaution that you will have to bear in mind while using loose diamonds on this shape. This variety is more prone to chips and cuts, especially around the corners. Make sure that the stones are well protected and properly set into the base when using them in any form of jewelry. 

These diamonds have a length to width ratio between 1 and 1.05 for square shaped stones. If you prefer rectangular select a ratio of 1.1 or greater.

Radiant diamonds

A cut relatively new to the diamond industry, introduced late last century. This unique cut is a hybrid of the round cut and the emerald cut. Radiant cut diamonds( as their name suggests) emit a beautiful glow. If you like the fire of round diamonds but prefer the shape of an asscher or emerald diamond, the radiant cut will present you with the perfect combination of both. As this shape shows more color we recommend opting for a higher color rating ( H , I or higher). These diamonds have a length to width ratio between 1 and 1.06 for their square shaped radiant. If you prefer a rectangular shaped radiant , choose a ratio of 1.10 or higher.

This cut is often described as pillow-shaped. When choosing a square shaped cushion, look for a length-to-width ratio between 1 and 1.05.

Emerald diamonds

Emerald diamonds

Emerald diamonds are known as the more sophisticated diamonds. The emerald cut is rectangular and has large step--facets. Because of this inclusions are easier to detect with the naked eye. For this reason we recommend diamonds with a clarity grade of SI1 or better when you select an emerald cut diamond. Due to its size and shape , the diamond is popular among budget conscious jewelry consumers. These shapes look best in rings that highlight clarity and size , typically settings with small accent diamonds.

Often used in rings, these gemstones can bring sophistication to any jewelry design, adding long lines and broad flashes of light. 

With their particular shape they can look larger than they actually are. These diamonds have a length to width ratio between 1.25 and 1.5.

Oval diamonds

Created by Lazar Kaplan in the 1950's the oval diamond is a perfect choice for the budget consumer.Cut with the same number of facets as the round shaped brilliant, the oval shape emits nearly the same level of brilliance and fire. With its elongated oval shape, it appears longer than a round diamond of equal carat. When set in a ring it creates the illusion of longer fingers , making it extremely flattering on the hand. Oval cuts have the disadvantage to show more color easily so we recommend selecting stones with a color grading of H or higher. These diamonds have a length to width ratio between 1.3 and 1.55 .
