CZ Round Machine-Cut Faceted Gemstone

This round CZ is machine-cut and features a bright-white flash and light-catching facets, making it an ideal choice for one-of-a-kind designs. Take advantage of its durability and use it to brush up on your setting techniques before moving on to softer gemstones or use it as a temporary stand-in for diamonds in custom show pieces. It sparkles when used on its own, but makes a larger statement when paired with colorful gemstones in more complex, necklaces, rings and matched sets. An economical alternative to diamond, cubic zirconia is a lab-created white gemstone that offers an excellent play of light and is also available in a variety of colors to complement a wide variety of gemstone-set designs. Round-cut gemstones are highly popular and the most commonly available. Rio round gemstones are calibrated for size and hand inspected to ensure maximum attractiveness.
