Description

    ROUGH AND CUT AMETRINE CRYSTALS
    Anahi Mine, Bolivia
    Ametrine is a rare form of quartz that is part amethyst and part citrine. Temperature gradients cause different oxidation states of iron in quartz, resulting in zonings of purple and yellow. Natural ametrine is extremely rare and only occurs in Bolivia and a handful of other countries. This large uncut ametrine crystal specimen features a rich purple amethyst with vertical zones of amber-colored citrine. The emerald-cut gem also displays the zoning between purple and yellow. Both of these are natural specimens that have not been enhanced; the crystal specimens measures 5¼ x 2¾ x 2¼ inches and the cut stone measures 31 x 23 x 13 mm and weighs 82.52 carats.
