Diamond shape refers to a diamond’s physical form, and is often one of the first attributes that couples consider when shopping for a diamond. While round diamonds are the most popular choice, many couples are also drawn to the distinctive look of non-round, or “fancy shaped” diamonds. Fancy shaped diamonds include princess, cushion, emerald, asscher, radiant, oval, pear, and heart shaped diamonds. Each diamond shape has its own unique characteristics and is cut to different specifications, which impacts the overall look of the stone.
