Amethyst Crystal - Single Point / Ametrine

An Ametrine single point from Bolivia. Purple amethyst and yellow citrine share a single crystal, separated by a sharp geometric boundary line.

The compact size is a typical ametrine collector's dimension. Material in this form is routinely recovered from the Anahí Mine and supplied to the international market.

Ametrine is a geologically unique variety of quartz. The only commercially exploitable deposit worldwide is the Anahí Mine in the Pantanal wetlands, Bolivia.

According to historical accounts, the Anahí Mine was discovered in the 17th century by Spanish conquistadors. The specific pressure-temperature conditions of this deposit create the two-color constellation.

A Bolivian ametrine piece with documented Anahí provenance and a clean two-color boundary.
