Here is an example of a nice deep black plume agate from Marfa Texas. You get a nice tall plume inclusion bing held together by a fine clear base agate. This type of cabochon my dad would say “it needs a little LED light behind it to light it up” and that is very true. The color is deep black and then when backlit by light the plumes just jump right out of the piece.
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.
