Zircon is a hard, naturally occurring gem mineral. Faceted zircon has a brilliance that rivals a diamond, making it an economical alternative. Most natural zircons are brownish orange; heat enhancement results in yellow, gray, green, red, blue or colorless stones. In the Middle Ages it was believed to protect against evil spirits, improve sleep and cultivate honor, wisdom and wealth.

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.
