Amethyst may exhibit one or both of two possible secondary hues, red or blue. A light rosy red, what we think of as pink, is the usual secondary hue found in lighter-toned stones. The ideal tone for amethyst is between seventy five and eighty percent; at this tonal level the secondary hue, if there is one, will be blue. The color in amethyst may occur in overlapping zones of purple and blue. When the stone is viewed face up, the color will be a slightly (ten to fifteen percent) bluish purple. The blue adds a velvety richness to the purple hue.
