Ametrine is a bi-colored variety of quartz, composed of amethyst, with purple hues, and citrine, with yellow to orange hues. Almost all polished ametrine gems are fashioned in an emerald-cut style to emphasize the color border. We had the oppotunity to analyze some remarkable ametrine images received courtesy of L. Allen Brown, the owner of All That Glitters from Methuen, MA.
