Color is the most important characteristics between amethyst's quality criterias. The finest amethyst color is strong reddish purple to purple with no visible color zoning.
Amethyst colors range from pale lilac to deep reddish purple and ranging from transparent to translucent quartz.

The finest amethyst is a deep purple color with minimal color zoning. It looks the best in daylight as compared to artificial lighting. The deep colors are the most valuable, especially a rich purple with rose flashes. Amethyst that either a weak or a light color or have zones of either light or dark purple colors are considerably less valuable.

The most priced amethyst, which sometimes might be called “Siberian” in the trade, is deep purple gem with red and blue flashes.
