Super color play in this Ethiopian opal, perched atop a simple but substantial hammer-textured cuff. All components are sterling silver. The opal has two small dots of potch, which is the silica opal is formed on. This cuff is size large, with a diameter of 2.5", and will fit up to a 7.5" wrist. I can trim it down if you need a smaller size. Let me know at checkout.
