This Petoskey Stone and Isle Royale Greenstone Tungsten Ring is Pure Michigan you can wear every day. Handcrafted in our Colorado workshop, it features a natural blend of Petoskey Stone and Isle Royale Greenstone, both hand-collected from the shores of Michigan’s Upper Peninsula. Each fragment is placed by hand and sealed with a durable epoxy that protects the inlay while highlighting the unique textures and colors of Michigan’s most iconic stones.
What Makes Each Ring Unique
No two stones are alike. Each ring shows its own mix of fossilized coral patterns and deep green hues, creating a one-of-a-kind piece that reflects the natural beauty of Michigan’s lakeshores. The inlay is sealed and polished for a smooth finish that is made to last.
Materials
Crafted from solid tungsten carbide with hand-set Petoskey Stone and Isle Royale Greenstone inlay. The durable epoxy finish allows for re-polishing as needed and holds up beautifully to active wear.

The most accurate way to find your ring size is by using one of our free ring sizing kits! These kits are a close match to all of the rings we make. Your fingers can change size throughout the day so make sure to try them on a few different times before deciding your size. You can even wear them around for a couple of days to make sure they’re the perfect fit.
You can also visit your local jewelry store to find your ring size. We recommend visiting two different stores to makes sure your sizing is consistent using a comfort fit band in the same width you plan to order.
Avoid using string or a fabric tape measure to measure your ring size, or the common zip tie measuring devices. It’s very important to use the same width ring sizer as the ring you intend to purchase. Learn more about common mistakes or ring sizing by watching our video here.
