Peruvian blue opals are usually found only in the Andes Mountains of Peru. In ancient times, they were considered to be a gift from Pachamama, the earliest Inca goddess of fruitfulness and Mother Earth. Today, some claim that Peruvian blue opals cure subconscious pain, have a calming effect and can alleviate sleep issues.

The catches are 14k gold, made in the USA.  Necklaces are strung in NYC.
