If your not a fan of Tiffany Stone then it’s OK. I will still be your friend. I have always loved it for the mixture that it is and the color it holds. This cabochon is a nice Bladed piece of Purple and Black with a little bit of Orange. The Blades are most likely a Barite pseudomorph.
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.
