What is a princess cut diamond?

Created in 1979 by Betzalel Ambar and Israel Itzkowitz, the princess cut is a square cut diamond featuring an inverted pyramid profile and 50 to 76 brilliant facets. It offers the maximum sparkle and fire of any square or rectangular diamond shape.

How are the corners of a custom princess cut diamond protected?

Because the corners of a princess cut diamond taper to sharp 90-degree points, they are more vulnerable to chipping if struck. At Riolls, our goldsmiths custom-build protective V-prong corner caps or bezel corner frames that shield the stone while keeping its clean square outline visible.

What is the ideal ratio for a square princess cut diamond?

For a traditional square princess cut diamond, look for a length-to-width ratio between 1.00 and 1.05. Ratios above 1.10 create a rectangular profile, which is less common for princess cuts.

Why do princess cut diamonds offer great value per carat?

When an octahedral rough diamond crystal is cut into a princess cut, up to 80% of the natural rough crystal is retained (compared to ~50% for round cut diamonds). This higher yield means princess cut diamonds are priced noticeably lower per carat than round diamonds of equal quality.
