A 1-carat asscher-cut diamond is absolutely stunning for its broader step-cut faceting. While buying a 1-carat asscher-cut diamond, one should prioritize balance within the facets for no visible inclusions, with a clean look that looks most elegant. For a rectangular shape, select the length-to-width ratio between 1.00 and 1.05 with excellent symmetry and balance for a bright and distinctive look.
