Large Natural Bismuth Crystal

This large bismuth crystal weighs approximately 1 to 1.1 pounds, with overall dimensions around 2.5 inches high by 3.5 inches long by 3 inches wide. Each cluster is has different shape and coloration due to its natural formation. The stepped geometric structure and rainbow coloration result from controlled cooling and natural surface oxidation during crystallization. Each one is unique and maybe different in shape and color than the photos.
