Color in Amethyst


Amethyst is an extremely popular gem because of its attractive purple color. Like the word “turquoise,” the word “amethyst” is now the name of a color as well as the name of a gem material.

While the word “amethyst” makes most people think of a dark purple gem, amethyst actually occurs in many purple colors. The purple color can be so light that it is barely perceptible or so dark that it is nearly opaque. It can be reddish purple, purple, or violetish purple. Amethyst exists in this wide range of colors.

Today much of the light amethyst is used to cut small calibrated stones for use in mass-market jewelry. Most of the premium reddish purple color amethyst is being used in high-end or designer jewelry.

While these names can be useful in conveying a generalized color, they are by no means precise or clearly understood by everyone.
