Ametrine is a bicolor quartz that has zones of golden yellow citrine and deep purple amethyst in contact with one another in a single crystal. The origin of the name is a combination of AMEthyst and ciTRINE to yield “ametrine.”

Ametrine is a rare gem, with most of the world’s commercial ametrine production from the Anahi Mine in southeastern Bolivia. The mine produces a variety of ametrine, amethyst, citrine, rock crystal, and bicolor gems.

Much of the ametrine is cut into stones with a traditional 50/50 ametrine/citrine split – but there are many ways to cut ametrine to obtain a maximum yield of unique gems from the mine’s production. The mine has been operated by Minerales y Metales del Oriente S.R.L. since 1989. The company is involved in mining, cutting, and jewelry production – to maximize the use of its ametrine resource.
