Michigan Greenstone Pendant Necklace
Most Michiganders (and even out-of-towners) know about Petoskey stones, Michigan’s official state stone. But few realize that Michigan also has a state gemstone.
Michigan Greenstone has been the official state gemstone since 1972. Also known as Isle Royale Greenstone, and scientifically known as Chlorastrolite, Greenstone is known for its star-like or “turtle-back” pattern. Exclusively found in the waters off the western Upper Peninsula, this stone polishes to a beautiful green hue and, on rare occurrences, can be dotted with natural copper flecks. Large stones, like these, are extremely rare. More often, you’ll find pebble or grain-sized pieces.
These pendants are set in Michigan-sourced copper on copper chains. Every stone is unique, making each jewelry piece a one-of-a-kind work of art. Created for Peninsulas by Detroit-based jewelry maker Bethany Shorb of Well Done Goods.
Bethany was lucky to acquire a limited number of Greenstones from a lapidary artist’s widow, a collection gathered long before it became illegal to do so. Her wish was for the stones to be treasured, and she let them go to Bethany for a price far below market value. We are passing this on to you.
