Also known as trystine or bolivianite, ametrine is a combination of both amethyst and citrine. This unique quartz variant has zones of both purple and yellow or orange. Ametrine first made its appearance in Europe through a gift to the Spanish queen by a famous conquistador.
To this day, most of commercially available ametrine comes from Bolivia, near the same mines the conquistador received his collection from. Ametrine can also be created artificially by differentially heating pieces of amethyst, though these pieces are considered less valuable and will be much cheaper in price.
Ametrine is a perfect for those seeking a unique quartz piece, as it contains two of the rarer variations in one. Because of its lack of naturally occurring deposits, however, ametrine is a rare gemstone whose hues and color combinations are absolutely unique.
