Here is a really nice little cabochon of Picasso Marble from Utah. The shape is fun and it has a nice 2mm girdle for bezel setting. I really like ho this piece came out and hope you do too. 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.
