A magnificent Opal specimen from Australia, with thick bands of white Opal running through the ironstone matrix, displaying excellent iridescence, with a play of colour from deep ultraviolet purplish-blue through green, yellow and orange. What we love most about this specimen is the tactile nature, as the Opal has been polished to follow its natural curves, retaining the thickness of the Silica layer, and the depth to the play of colour. Gorgeous, even better in person!
