Amethyst takes its name from the Greek word “amethysos” and is a translucent quartz popular for generations and among royalty. It can vary in shades of pink-purple to blue-purple, from sweet grape violet to pink and more reddish-brown-purple tones less commonly used in jewelry. Color may be less uniform throughout the quartz, but this does not always detract from its use in gemstones, although deeper, richer hues of the violet color are most desired. Amethyst gets its tranquil color from manganese and iron, and when heated (irradiation), the iron changes, offering different colors. Sometimes this process is used to create a two-tone colored stone of Amethyst violet and yellow-orange citrine generally used for gem collections. The bright and deep tones of Amethyst give it a soothing appeal for spring and summer wear jewelry, either alone or with other fruit colors, but can also be matched with white, black and gray translucent stones for striking and more classical jewelry.
While quartz can render both opaque and translucent stones, violet Amethyst embodies the rich color desired for multi-faceted cuts. This makes it prime for round, oval and teardrop cut settings. The natural crystalline composition of both right-handed and left-handed quartz called lamellae gives Amethyst a highly refractive appearance. This is the added sparkle desired in gemstones and also makes Amethyst less likely to be lab-created.
Amethyst in its freer and more natural states of geodes and rough are beautiful straight from the mine, or upon opening, in the case of geodes. Unlike some gemstones, it often appears faceted before a jeweler’s intervention. This is due to quartz’s superb nature for sharp angles and vitreous or glossy luster. The ability to stay brilliant even with dome shape polishing makes Amethyst ideal for cabochon settings and beads in tube, triangle, round, and oval shapes. Amethyst refers to the violet shade of the quartz gemstone, but occasionally ‘green’ Amethyst is mistakenly used in place of the correct term for the exotic green quartzes of prasiolite or vermarine.
