Here is a really nice example of Dinosaur Bone from Utah. A classic red on maroon contrasted color with light cellular or webbing patterns. Fun freeform shape that will suite wire wrapping best but can be bezel set. The back is not high gloss polished as this is an older cabochon and is sanded to 600 grit and well worth my asking price.
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.
