Here is a rind cut of Brazil agate which may be a type of Piranha agate, I am not sure. The deep yellow jasper like rind would go into a black color with almost no pattern on the inside of the agate. But the pattern along the rind which i have captured in this piece is really nice.
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.
