For something truly unique, this is not your standard high-quality opal. This is something very special. This solid Australian opal is a belemnite, a fossil from an ancient sea creature similar to a modern-day cuttlefish. A spectacularly beautiful crystal opal and also a very rare fossil, all in one. Adorned with 36 point of high-grade diamonds and set in 18K gold and platinum 950. True High Jewellery, this ring is a handcrafted one-off masterpiece.
