What Is Diamond Shape?

Diamond shape refers to the geometric appearance of a diamond. Diamond shapes are categorised into two groups: round diamonds and fancy shape diamonds. Round diamonds, also known as round brilliant cuts, are the most traditional diamond shape. Fancy shape diamonds refers to any diamond that is not a round brilliant. Tiffany fancy shape diamonds include princess, cushion, emerald, oval, pear, marquise, heart and our exclusive Tiffany True® diamond.

Round Brilliant Diamonds

The round brilliant cut is one of the most popular diamond shapes for its intense sparkle. Round brilliant diamonds are cut to optimise brilliance, featuring over 56 facets that reflect light and cast tiny rainbows in a breathtaking show of sparkle and contrast. Since 1886, the Tiffany® Setting has featured a round brilliant diamond, becoming an icon against which all engagement rings are measured. Leading the industry, Tiffany offers a triple excellent cut on all round brilliant diamonds.

Boasting over 50 chevron-shaped facets, this cut is defined by exceptional fire and scintillation. Depending on the length-to-width ratio, princess-cut diamonds can appear square or rectangular.

Pear-Shaped Diamonds

The pear shape combines round brilliant and marquise-cut styles to form a tapered teardrop with an extraordinary display of light. Like oval and marquise diamonds, the flattering pear shape elongates the finger – especially when worn with the point facing the nail. Tiffany pear-shaped diamonds showcase exacting symmetry and are exceptionally beautiful in halo settings.
