Peruvian pink opal is relatively rare and is only found in the Andes Mountains near San Patricio, Peru. The pink opal derives its color from trace amounts of included organic compounds known as quinones. These opals range from opaque to translucent, and depending on how the stone is cut, the color will either be clear or show the stone’s matrix and inclusions. (Like agates, some Peruvian opals show the scenic fern-like dendritic inclusions.) Peruvian opal is also known as Andean opal.
