The Signature 16mm pendant is a simple but stunning design. Included in Lost Sea Opal's signature collection, this 18k gold piece is a stunning showstopper for everyone. This particular opal is a deep blue but flashes an electrifying, bright green when caught at the right angle. The black opal was mined locally at the Lightning Ridge Opal Fields, and the piece was handcrafted in our Lost Sea Opals workshop.
