It's organic shape is made of bright shiny areas and natural green patina. Safely held by a 4-prong sterling silver setting. Bail opening is 6mm. The first to mine the copper there were Native Americans (5000-1200 BC). Modern mining started around 1845 and by 1850 Michigan produced more than three-quarters of the nation's copper, and in 1869 produced more than 95% of the country's copper. Annual production peaked in 1916, by 1968 most deposits were mined out. You will receive the very same pendant shown in the pictures, in an elegant jewelry box and ready to be given as a gift.
