It is a yellow variety of quartz. Its name comes from the Latin "citrus", this gem owes its name to its lemon yellow color due to its iron content but the name was male until the seventeenth century (citrine quartz). The natural citrines, of a very pure and bright yellow, are actually quite rare, most of them being amethyst or smoky quartz, heated, but then their color turns more towards the brown-red.
The ametrine is a bicolor variety of quartz , also called bolivianite or trystine for half amethyst and half citrine. Its name reminds the amethyst and citrine.
The Ayoreos Indians living in the El Chaco region, east of Bolivia, about thirty kilometers from Brazil, discovered it entangled in tree roots. They exchanged it for food with the Spanish invaders.

Historical stones and related legends

Long time ago in a remote boundary of Bolivia and Brazil, a sorcerer imprisoned in a crystal the violet mantle of dawn, but the sun, angry, hid it deep within the Earth. Longtime after, a conquistador had shown to his monarch in Spain a sample of this rock that was given to him by a descendant of the sorcerer, a princess of the Ayoreos tribe with whom he was married. However, the people to whom the princess belonged preferred to sacrifice her rather than see her go away. Dying in the arms of her husband who embraced her, she placed in his hands in an ametrine, a pledge of eternal love. The mine still bears her name in the nineteenth century: Anahi. The miners say that from time to time, the calm is broken by the cries of the conquistador.
