Description

This AAA-grade round amethyst displays a deep saturation of dark purple color ideal for high-end designs. The color, hardness and versatility make amethyst one of the most popular gemstones in jewelry design and its color is complemented by either white or yellow metals. This stone shows the superior cut, color saturation and active scintillation required to be classified as a top-quality AAA-grade stone. Amethyst is the birthstone for February.

Amethyst is the best known and most valuable form of quartz. The color of natural amethyst is caused by iron or manganese compound impurities in the mineral and can range from a watercolor pale pink to a dark, almost opaque, purple. Named for the Greek word for “sober,” amethyst was believed to remedy drunkeness. As a crystal, amethyst is credited with relieving stress and promoting peace of mind.

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.
