Made from lab-grown spinel, this round faceted gemstone offers an attractive medium-blue color and offers an economical alternative to zircon, the birthstone for December. Highlight its vibrant color by using it in a custom pendant design or partner it with complementary-color gemstones in multicolor matched sets with earrings and rings. 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.
