Ametrine is a true wonder of nature, combining two marvelous varieties of Quartz in a single gemstone.
The name Ametrine derives from its composition of Amethyst and Citrine, and refers to the presence of both of these gems in a single stone.
Chemical composition of Ametrine
From a mineralogical standpoint, Ametrine combines Amethyst and Citrine within itself, creating a mesmerizing whole. Both gemstones belong to the Quartz mineral family; varying stages of iron oxidation give rise to this particular combination.
The examples of Ametrine suitable for mounting in jewelry are only found in a single place, the mine of Anahisi, near La Baiba, in Santa Cruz, Bolivia. It is occasionally also extracted in Brazil, India, Madagascar and Sri Lanka, but not in sufficient amounts for commercial use.
History of Ametrine
Ametrine is a relatively new entry on the precious stone market - first sold in 1980, but immediately highly sought after for jewelry.

Properties of Ametrine
As a variety of Quartz, Ametrine displays a rare multi-hued beauty, delicately blending the feminine purples of Amethyst with the yellows of Citrine. This chromatic encounter occurs within its clear, almost transparent crystals, allowing Ametrine to better display its brilliant and beautiful colors.
Varieties of Ametrine
Ametrine is usually cut so as to display the two different colors in perfectly identical parts. For Sunburst Ametrine, however, a particular cut that creates an optical interplay between the two colors is preferred, creating a wonderful effect that gives the gemstone a unique depth.
Care for Ametrine
Ametrine may never be subjected to steam cleaning or ultrasound.
