If you are looking for a one of a kind mineral specimen, this would be it! Bismuth is a metallic chemical element with some fascinating properties. With the atomic number 83, it is 86% as dense as lead, making it curiously heavy in the hand. It is also the most diamagnetic natural substance which means it is actually slightly REPELLED by a magnet. Bismuth is one of only a few substances, water being another, that actually expands upon freezing (solidifying).
This mineral specimen is in its natural raw state.
Miners during the Middle Ages apparently believed bismuth to be a stage in the development of silver from baser metals and were dismayed when they uncovered a vein of the metal thinking they had interrupted the process.
Measurements: This mineral specimen is 2 inches tall and is 2.5 inches in width.
