Emerald, a green variety of beryl, gets its color from traces of chromium and vanadium in its crystalline structure. Many emeralds are treated with Opticon or oil to enhance their color. All Rio Grande emeralds have been oiled; we do not offer emeralds treated with Opticon.
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.
