Ametrine, also known as trystine or bolivianite, is a gem-quality material produced solely at the Anahí Mine in Bolivia. It's a quartz that displays bands of both purple (amethyst) and yellow (citrine), with the most desirable stones having an even 50/50 color split ranging from pale-violet to deep-purple and from pale-yellow to gold-brown. The color transition in ametrine reflects slight fluctuations in temperature and pressure during its formation, which can lead to the formation of amethyst or citrine zones within a single quartz stone. Ametrine can be used as the birthstone for February and November.
