Ametrine, also known as trystine or amethyst-citrine, is a unique gemstone that combines the violet hue of amethyst and the yellow tint of citrine. As a result, it exhibits a beautiful blend of two contrasting colors. Alternatives for ametrine include bicolored quartz, amercitrine, and bolivianite. Bicolored quartz is a term used to describe any variation of quartz with two distinct colors. Amercitrine, a name coined by the Jewelry Television network, refers to the natural combination of amethyst and citrine. Bolivianite is a type of ametrine that is exclusively mined in Bolivia and displays a broader spectrum of colors compared to other types of the gemstone.
