I have seen this material label from a Idaho location but I do not recall the name it was going by. This piece came from a collection long ago and I had cut it so many moons ago as well. It has a real nice large tube formation in a clear to white agate with a little bit of quartz heart showing through. Nice fat piece I really enjoy the contrast and shape.
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.
