Peru is known for its fine opal, particularly blue and pink opal gemstones. These beautiful pastel-colored opal gemstones do not generally exhibit the play of color that is highly-prized in precious opal, but have very attractive body colors. Chrysocolla gemstones, which are sometimes traded as "Peruvian turquoise" because of their resemblance to the blue to green gemstone, are also mined in Peru. Like turquoise and azurite, chrysocolla is a copper-bearing gemstone that is typically cut en cabochon. Due to its mix of blue and green, and unique patterns, no two chrysocolla gems are the same.
