Each of the cushion cut diamonds in this video were personally hand selected by our gemologists for TOP light performance and are good examples of 3 flavors of cushion cuts we feature with top optical properties. One is a Square Cushion Hearts & Arrows Diamond, the 2nd is a traditional Cushion Brilliant and the 3rd is also a traditional Cushion Brilliant but faceted a bit more modern. Each are spectacular though as we view them under both diffuse and spot lighting for an examination of brightness, patterned scintillation, fire and sparkle. This video is NOT a comparison of a common doggy cushion vs a beaut as all 3 are beauts. :)
