Ametrine is a color-zoned variety of macrocrystalline quartz. It is sometimes referred to as trystine and is a natural bicolor combination of amethyst and citrine. Color band combinations in ametrine can range from pale-violet to deep-purple and from pale-yellow to gold-brown. Ametrine's color split is rather abrupt and is not a smooth blend of colors.Ametrine stones, like most other clear quartz varieties, are typically eye-clean and transparent. When cut and polished, they have a vitreous luster. Stones with 50/50 color splits are considered the most desirable.
