This beautiful thunderegg is one of the most finely formed Black Rock desert eggs I have seen - as well as one of the most beautiful of all my eggs, in my opinion. The mix of red and green is stunning. It has a striking brick red outer matrix and a remarkable interior of light blue and clear agate, a patch of black agate and, most interesting of all, a small growth of 'moss' around the edges. It also has a tiny and unexpected crystal cave in the very center.
