Cut style= Dome top It features mostly black obsidian with some suspended ribbons of metallic looking fire. You can only see the fire in sunlight or bright light, indoors it will mostly look black. There are a few tiny pits in it.
All cabochons in my stone shop are cut by my own hand with love and care. I pay special attention to perfect evenness on every angle of the stone. This makes the gemstone easy to set with a bezel. The bottoms of each are flat and have a very slight bevel cut into the bottom edge. This cut serves to minimize the chance of chipping when setting into hand fabricated metal bezels or wire wrapping. Thanks for looking.
