Here is a nice little Boulder opal Cabochon. It was tumbled finished and it still has a bit of rough areas to it. Almost no fire color but there is some there along one of the sides. A nice crafting piece or wire project when you need a Ironstone opal in the mix. I believe it to have a lot of contrast and would show off very well in a setting or crafting jewelry project. Boulder Opal can come in many forms and can produce some of the most brillant fire in all of the Opals found around the world. When I see these opals at gem-shows I get really excited.
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.
