Peruvian Opal is some of the loveliest we are seeing on the market today. It's showing up in pale blues and greens and also in a peachy pink. These particular pieces are of the former, and are graced with brown streaks of matrix running through here and theres. Also along side are some gorgeously faceted smokey quartz rounds, adding to the overall elegance and style of the piece. 14K yellow gold components, including toggle clasp.
