Round Brilliant Cut

The optimal pear shape is one with a polished girdle and a rounded base, or “even shoulders”. However, much like the oval cut, a more attenuated pear shape may elongate the fingers, so it is important to reconcile these two qualities. Additionally, colour is often more visible towards the tip of the pear shape, so to ensure an even tone throughout the stone it is advisable to opt for colours H and above.

Because of its extra facets, the Cushion cut can disperse more light through the stone which serves to hide inclusions more efficiently, making it one of the most brilliant of all square- and rectangular-shaped stones.

The most important elements to consider with the heart shape are the quality of the curved cut and finish as these determine the sparkle of the gem.

Ratio is an important aspect to consider with the oval shape as it can have a significant impact on both the light dispersion within the stone and the appearance of the finger. When selecting an oval shape it is important to reconcile the relative benefits of the longer shape (larger ratio) and the more rounded shape (smaller ratio). The former will better elongate the finger, while a more rounded shape will better prevent the bow-tie effect.

Because of its extra facets, the Radiant cut can disperse more light through the stone making it one of the most brilliant of all square- and rectangular-shaped stones. It also hides inclusions more efficiently than other shapes. As it is a hybrid cut combining the features of both brilliant and step-cuts, the Radiant is the ideal compromise and the perfect solution for someone who wants to “have it all.”
