Created to exacting standards, using state-of-the-art gem-lab technology and minute attention to detail, this lab-created emerald has a chemical make-up identical to the finest Colombian emeralds. Its color is a more intense green than the natural stones can offer, and it performs at the bench just as a natural stone does. Unlike natural emeralds, however, this stone is heat-resistant and can be successfully cast in place and can be fired in place in silver PMC3 at the lowest temperature schedule. 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.
