Ametrine, also known as trystine or by its trade name as bolivianite, is a naturally occurring variety of quartz. It is a mixture of amethyst and citrine with zones of purple and yellow or orange.
Ametrine is said to be the complete balance of the properties of amethyst and citrine. As a stone of both balance and connection, ametrine is believed to relieve tension, bring serenity and stimulate creativity, as well as balance mental stability and self-confidence.
