Dark Amethyst Crystal

A dark amethyst crystal from Bolivia. Pure amethyst zone without the typical citrine component, a gemologically rarer find from the Anahí mine.

Unlike the typical ametrine pieces from the Anahí mine, this piece exclusively shows the amethyst zone. The citrine component is missing. Such pure amethysts from the Anahí mine are rarer than the two-color constellations.

Ametrine is a geologically unique variety of quartz with purple amethyst and yellow citrine in a single crystal. The only commercially viable deposit in the world is the Anahí mine in the Bolivian Pantanal swamp region.

According to historical tradition, the Anahí mine was discovered by Spanish conquistadors in the 17th century. The daughter of a local chief named Anahí is said to have been married to a conquistador. She gave him the mine as a dowry.
