A round cut diamond, also known as a round brilliant cut, is a diamond that has been cut into a rounded shape. This is the most popular diamond shape and represents most diamonds sold. The round cut diamond boasts 58 facets (including the culet) and offers exceptional white light reflection, also known as brilliance.
A brilliant cut diamond is designed to maximise the light reflected from the diamond, creating a high level of sparkle and brilliance. The round brilliant cut is the most popular version of this cut, featuring 58 facets that reflect light to and from each other, enhancing the diamond's overall brilliance.
A brilliant round cut diamond is highly regarded based on GIA grades. The Gemological Institute of America thoroughly assesses the cut, colour, clarity, and carat weight. A round brilliant cut diamond with an Excellent or Very Good cut grade ensures optimal brilliance and sparkle. Favourable colour grades range from colourless (D) to near-colourless (J), while higher clarity grades signify fewer visible inclusions. The carat weight determines the diamond's size. A round brilliant cut diamond with positive GIA grades is considered a top-quality diamond with outstanding visual appeal.
