Made from lab-grown corundum, this round gemstone displays a deep red color and is an economical alternative to natural ruby, the birthstone for July. 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.
