Natural Ametrine
Virtually all natural ametrine comes from the Anahí mine in Bolivia. Value rests on a crisp, well-centred boundary between purple and gold, and on a cut that presents both colours evenly through the table.

Natural ametrine is untreated. Synthetic and heat-zoned imitations exist, so provenance matters.
Warm soapy water. Avoid prolonged sunlight and sudden heat, which can blur the colour boundary.

Common questions
What causes the two colours in ametrine?
Different oxidation states of iron in adjacent growth sectors of the same crystal, formed under a natural temperature gradient. One sector becomes amethyst, the neighbouring one citrine.
Where does ametrine come from?
Nearly all commercial natural ametrine originates from the Anahí mine in eastern Bolivia. Material claiming other origins warrants scrutiny.
How should ametrine be cut?
The best cutting places the colour boundary along the centre of the stone so both colours read equally face-up. Emerald and rectangular cuts show the division most cleanly.
