If you know this material it is really well know to have lots of inclusions that look like fractures. This cabochon has these examples but the color is super nice and at 4mm thickness. I did not want to make the piece any thinner or flatter and just couldn’t remove that little pit. Polished on both sides.
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.
