Ametrine earrings combine two quartz varieties in a single stone, displaying zones of purple amethyst and golden citrine side by side. This natural phenomenon occurs when iron oxidation states differ across crystal sections during formation. Our collection features 9 pairs set in .925 sterling silver, priced from $1043 to $2558. Each stone originates from Bolivia's Anahi Mine, the world's primary commercial source for natural ametrine. Free US shipping on all orders.

Nearly all commercial ametrine originates from Bolivia's Anahi Mine. This deposit produces stones with distinct purple and golden color zones in the same crystal.
Ametrine measures 7 on the Mohs hardness scale, the same as standard quartz. This hardness level resists scratches from daily wear and suits earring use well.
Temperature differences during crystal formation cause iron impurities to oxidize at different rates. This creates distinct amethyst and citrine zones within one stone.
