This is a Thunderegg half from Oregon, cut and polished by me. It's primary color is brown with some reddish tones and even a little yellow. A beautiful, jagged packed crystal smile can be seen with just a hint of blue agate at the edges. Use as a pocket stone or desk decor in home or office. Due to this being made by Mother Earth and my hands imperfections will exist. You will receive the exact thunderegg half pictured.
