This truly unique piece of Queensland Boulder Opal astoundingly changes colours as it descends down the piece. It lives inside a 14ct Gold elegant and simple pendant setting and measures in at 30mm high x 8mm wide. This Australian opal was mined in the Yowah mining region at my friends mine called Brandy Gully. As with all our jewelry it is hand mined, cut and polished and set by us. Enjoy something truly handmade and ethically mined and made.
