Loose Russian cubic zirconia stones in every popular shape and carat size—round brilliant, princess, cushion, Asscher, radiant, and more—plus fancy colors. Perfect for custom settings, repairs, and replacements.
Round Brilliant - This is the most classic cut. A well made round brilliant diamond has 58 facets, is symmetrical, well polished, and reflects a very high percentage of the light that enters it - thus its name -round brilliant.
Marquise - The Marquise diamond is an elongated brilliant-cut stone with a point on each end, which can vary in shape from long and slender to a shorter, broader appearance. In general, marquise diamonds are approximately twice as long as they are wide, but some prefer the look of a longer or shorter stone.
Radiant/Emerald - Usually rectangular, this cut demonstrates a classic elegance. Fully faceted for maximum brilliance, unlike the traditional step cut that are very transparent. Beautiful Gem Quality AAAAA
Oval - While reminiscent of the round brilliant cut, both in sparkle and shape, the oval maintains its own brand of elegance, and has recently become a very popular centerpiece for engagement rings.
Heart - A more fanciful cut, shaped just as it sounds, heart shaped diamonds make truly beautiful pendants and earrings, and have now begun to gain in popularity as engagement stones.
Pear - A pear or teardrop shaped diamond combines the brilliance and form of a round stone with the elongated elegance of a marquise. While a pear is generally half again as long as it is wide, some prefer the look of a longer or shorter stone.
