Ametrine are two colored quartz that contain both violet amethyst and yellow-brown citrine.

Ametrine is only found in Bolivia.   It is known as trystine or by its trade name “bolivianite.”  Legend has it that ametrine was first introduced to Europe through a conquistador’s gift to the Spanish Queen, after he received the Anahi mine in Bolivia as a dowry.

Ametrine could be imitated by heat treating of amethyst.
