    Yes, cushion cut diamonds look larger than round cut diamonds. Cushion cut diamonds have a larger table per carat than round diamonds, making them appear larger. This coupled with cushion cut diamonds' larger facets, tend to make these types of diamonds appear larger to our eyes.
  • 1stDibs ExpertFebruary 22, 2021
    A 4 prong makes a diamond look larger than a 6 prong because there is less of the stone's surface covered up by the prongs. 4 prong mounting also allows for more light to fall onto the stone.
