Round cut diamond rings

The round cut has traditionally been the most popular diamond shape for engagement rings going back several decades and it remains in high demand to this day. The mechanics of the round shape make it largely superior to intricate, more complex shapes and allow it to achieve maximum brightness through the reflection of light.

Brilliantly cut round diamonds generally have a depth of between 59% and 63%, in alliance to a crown angle of 34.5%. Colour is subjective, but the highest quality round diamonds are colourless (grade D-F) and come with absolutely no inclusions (Flawless) or miniscule inclusions invisible at 10x magnification (Very, Very Slight Inclusions).
