    Ametrine
    Ametrine is a variety of bicolor quartz that has zones of amethyst (purple) and citrine (golden yellow) in contact with one another in a single crystal. The words AMEthyst and ciTRINE were combined to yield the name "ametrine," which is widely used in the gemstone trade. This material is known by other less-frequently used names including: "amethyst-citrine," "trystine," "bicolor amethyst," "bicolor quartz," and "bolivianite." The bolivianite name is a response to the material being designated as the national gemstone of Bolivia.

    A crystal containing both amethyst and citrine in contact with one another can be called "ametrine." These crystals usually contain zones of clear quartz, amethyst, and citrine. When these crystals are cut into pieces that are appropriately sized for faceting gemstones, only a portion of the stones will be ametrine. The remainder will be amethyst, citrine, and clear quartz. This is why the Anahi Mine produces a variety of gem materials and why the amount of ametrine produced is limited. ________________________________________________________________________________________________________________________________ Information Source: Author Hobart King Article title: Ametrine: A Bicolor Gemstone of Amethyst and Citrine Website title: Geology.com URL: https://geology.com/minerals/quartz/ametrine.shtml
