A Tiger or Leopard?
This is ametrine, a gem from Brazil. Ametrine [ah-muh-treen] is a combination of the colors of citrine [sih-treen] and amethyst. The cutting style of this gem blends the colors to create the look of a tiger or leopard's coat. - Photo by Robert Weldon/GIA, courtesy of Minerales y Metales del Oriente
