Lab-Grown White Sapphire Round Faceted Gemstone

Made from lab-grown corundum, this round white sapphire displays a brilliant white clarity and offers an economical alternative to diamond, the birthstone for April. Each gemstone has a chemical make-up identical to those found in nature. It performs at the bench just as a natural gemstone would. 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.
