This material comes from California and is very interesting. I have only ever cut this single one piece of it in my life. It is very hard stuff but very pleasing to the eye. The color is deep green and actually does show well even in shade on how the green color looks to the eye. The magnetite inclusions you can see as little dark silver sprays throughout the cabochon. A must add to your collection.
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.
