Ametrine

Amethyst is a purple quartz. Citrine is a yellow quartz. Quartz that displays bands of both purple and yellow is known as Ametrine. Gem-quality Ametrine is sourced from only a single site in Bolivia. Emerald cuts and fantasy carvings are popular ways to showcase the dramatic color zoning in this very durable gemstone.

Like most quartz gems, ametrine occurs in fairly large, clean pieces. Thus, the price per carat doesn’t increase with larger size stones. Ametrine prices are rather modest. As far as the material itself, the depth and vividness of colors and the distinction of the color separation are the main value points.

The artistry of the cutting or carving adds most of the value to many ametrine pieces. You’ll find a world of difference between a commercial grade or native cut and a fine custom stone, even when cut from the same rough material.
