PrincessPlus® 
PrincessPlus is the result of years of research into the light performance of square cut diamonds. This exceptional diamond, fashioned with over 100 strategically placed facets, is brightest princess cut ever created.

What is a Brighter Princess Cut?

When talking about diamonds, brightness is defined as the total amount of light that is reflected by your diamond. If this is confusing, think about brightness as the sparkle you get from a diamond. Many people define the beauty of a diamond by how much it sparkles. Using the PrincessPlus® light return certificate, you are able to see a scientific analysis of the beauty of these diamonds.

Certified Diamonds

Most of these diamonds also receive a “4C’s certificate” from an independent gemological laboratory. These PrincessPlus diamonds are graded for cut, color, clarity and carat weight. Additionally, the certificate number assigned by the laboratory has been inscribed on the inside of your PrincessPlus ring. This is an assurance that the diamond that has been certified is the same one that has been set in your ring.
