Amethyst gemstones have captivated humankind for centuries. The lilac-to-deep purple hues were once reserved for royalty or religious figures who wore it as a symbol of their important stature in society. Its lore comprises several claims to mystical powers, including that it would convey strength and wit to those who wore it. Amethyst was also associated with Bacchus, the ancient Greek god of wine, and wearing it was thought to keep the drinker sober.

Amethyst belongs to the quartz species and is related to rock crystal, citrine, prasiolite (a rare, greenish variety of quartz) and agate (a variety of chalcedony).

Amethyst is the February birthstone


Amethyst ranges in purple hues from deep royal purples to lighter, lilac-shades. Nature produces a variety known as ametrine, a combination of amethyst and citrine. This gem is purple and yellow and is frequently cut to show its division of color or in a way that mixes the colors, forming interesting medium dark to moderately strong orange, and vivid to strong purple or violet hues.


Amethyst gemstones can be cut into many shapes and sizes, often as cabochons or beads, and is also carved for ornamental use.


Russia was a classic source for amethyst. Current sources include Brazil, Bolivia, South Africa, South Korea, the United States, Uruguay and Zambia.


Amethyst is a fairly durable gemstone with a hardness of 7.0 on the Mohs Hardness Scale.


On some occasions amethyst is heat-treated to lighten overly dark gems. Any treatments should be disclosed to the buyer.


Amethyst can be manufactured in a lab, instead of being sourced from a mine. This information needs to be clearly disclosed to the buyer.
