Silver

A very rich, 152gram chunk of native silver showing some crystal forms and a bit of acanthite cabinet growth in one area. Dense!

Silver was discovered on the shores of Cobalt Lake in the summer of 1903. Within a few years, Cobalt became one of the world's largest silver producers, supplying an astonishing 333 million ounces, or more than 10,000 tonnes, of silver by 1922 from 100 mines.
