Lab-Grown Emerald Round Faceted Gemstone

Created to exacting standards, using state-of-the-art gem-lab technology and minute attention to detail, this lab-grown emerald has a chemical make-up identical to the finest Colombian emeralds. Its color is a more intense green than the natural gemstones can offer, and it performs at the bench just as a natural gemstone does. Unlike natural emeralds, however, this gemstone is heat-resistant and can be successfully cast in place. Emerald is the birthstone for May. 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.
