Ametrine is a beautiful Quartz which has both Amethyst and Citrine colors in the same crystal. Ametrine is bi-colored with purple and yellow flashes.
Only one mine in the world produces Ametrine; the Anahi Mine in Bolivia. A Spanish conquistador received the mine as a dowry when he married Princess Anahi from the Ayoreos tribe. The conquistador gave Ametrine stones as gifts to his bride, and the gem was thus introduced to Europe.

Ametrine is generally a 50/50 pairing of Amethyst and Citrine, fashioned in a rectangular shape. Occasionally a checkerboard pattern of facets is added to the top to enhance light reflection. It can also be cut to blend the two colors so that the resulting stone is a mix of purple, yellow, and peach tones. Ametrine is also popular among artistic cutters and carvers who play with the colors, creating landscapes in the stone.
Ametrine is a very durable gemstone suited for a variety of jewelry uses. The color contrast is most pronounced in sizes over seven carats, but the stone can be found in several sizes and shapes.
