Faceted ametrine from Brazil 18,5ct

Ametrine is a rare variety of quartz that naturally combines two well-known gemstone varieties within a single crystal – purple amethyst and yellow citrine. The combination of these contrasting colors makes ametrine one of the most fascinating gemstones used in jewelry and mineral collecting. Its formation is associated with different oxidation states of iron within the crystal and the influence of temperature during geological development.

For faceted ametrines, the most important quality factor is the distribution of color. The most highly valued stones display a distinct and sharp boundary between the purple and yellow sections. Ideally, both colors should be vivid, well-balanced, and occupy approximately the same area. Pale shades or unclear transitions between colors reduce the value of the gemstone.

Most high-quality ametrines on the world market come from the Anahí Mine in Bolivia, which is considered the most important deposit of this quartz variety. As a result, the trade name Bolivian ametrine is frequently encountered. Material from this locality is renowned for its exceptional clarity and strong color contrast.

Among collectors, larger faceted ametrines with high clarity and well-defined color zoning are especially sought after. Modern fantasy cuts are also popular, as they maximize the stone’s color zoning and create unique optical effects. Thanks to the combination of two colors within a single gemstone, ametrine is an attractive and unusual mineral that continues to gain popularity around the world.
