Blue tiger as some folks call it. This piece has a variegated golden mixture with the blue which is not uncommon. The color is very nice and the flash is good. The grade of the material is grainy however and the price reflects that. Nice cut and nice bezel for easy setting into your jewelry creation.
Visit my Sold cabochon Gallery to see past opals I have cut. You will find other examples of materials, shapes, sizes, colors, and in general see my work there. Some stones date back over 15 years in there. I don’t show everything I cut, just the ones I really liked over the years. Please let me know if you have any questions about those materials.
Its also important to visit your local rockclub if you have one near by. Its a great place to start if you are new to gems and minerals. Thank you.
