1.8 carat Australian opal adjustable ring, stone from Coober Pedy. Stone is a white base with rainbows underneath. Stone size is approx. 10mm diameter. Reminder, I'm not a jeweler and these rings were originally made for just me. I prefer the stones natural looking with possible matrix, inclusions or some polishing scratches. These are all created from rough rocks that I grind and polish into cabs.
