Bismuth

Diamagnetic Chemical Element
Bismuth is a chemical element, a pentavalent poor metal, chemically resembling arsenic and antimony. Until the 18th century it was often mistaken for tin or lead. Yet once refined in to its purest form it becomes a thing of great beauty.

About twice as abundant as gold, the chance are you have come unwittingly into contact with it if you have ever had a minor digestive upset. As a bismuth oxide core structure with salicylate ions attached to the surface you probably know it as Pepto-Bismol.
