Ametrine

Ametrine is a rare, natural blend of citrine and amethyst. The combination of amethyst and citrine creates a two-tone effect called color zoning, and this effect makes each ametrine unique. Ametrine is also a single source mineral, and as such is very rare and difficult to obtain. The only known source for ametrine is the Anahi Mine in Bolivia. Ametrine was closely guarded and controlled by the Bolivian government until 1989, when the government relinquished control of the mine.

Ametrine is a member of the quartz mineral group. Ametrine has a hardness of 7 and a specific gravity of 2.66. Ametrine is only found at the Anahi Mine in Bolivia.
