Amethyst Crystal - Single Point / Ametrine

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

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

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

In this point, the color banding is particularly accessible. The boundary between the amethyst zone and the citrine zone runs clearly visible through the crystal.
