The quadrillion cut has a unique facet arrangement that creates a star-like appearance on the gemstone’s crown. It is square shaped and has 49 facets and sharp corners. The cut is trademarked by Ambar Diamonds Inc. The quadrillion cut is similar to the princess cut, but unlike the princess cut, which is cut for weight retention, the quadrillion cut is cut to maximize brilliance. Every quadrillion cut ring is stamped ‘Quad” on the shank or band and accompanied by a certificate.
