Ametrine





General Information:

Ametrine is a variety of quartz that is a blend of Amethyst and Citrine. This beautiful gemstone is only found naturally in Anahí mine, in eastern Bolivia. Ametrine like all other quartz is composed of silicon and oxygen, and it gets its two distinct colors from iron impurities. More commonly found separately, amethyst and citrine have the same composition, it is the impurities in the mineral that creates the two forms of these quartz varieties. Ametrine is yellow and purple, and most commonly cut in rectangular shapes. The ideal gemstone will have a good 50/50 color split.

Origin:
Ametrine is found in Bolivia.
