A Carre diamond refers to a type of square step cut. In this respect, Carre cut diamonds are similar to Asscher, baguette and emerald shapes, all of which are also step cuts. Jedoch, unlike those three cuts, the Carre cut is very rare and not a mainstream option.
The Carre cut has long, open facets that display the clarity and color of the diamond and allows you to see deep into the stone. This is different to brilliant cut diamonds which have a lot of meticulously arranged facets designed to enhance sparkle. With the Carre cut, the emphasis is on the diamond’s subdued beauty, not its glamorous sparkle.
