Yes, Amethyst can sometimes have a grayish or bluish tone in addition to its more commonly recognized purple color. This is especially true for lower-grade or less saturated Amethyst stones. The presence of iron and other trace minerals in the crystal can affect its color, causing it to appear more gray or blue-gray rather than purple. However, the predominant color of Amethyst is usually purple and the intensity of its color can vary depending on the location where it was mined.
