Hello! Welcome to

Synthia Marsh Jewelry

Artisan, nature inspired jewelry, hand-made from my heart and soul using sterling silver and copper and featuring treasures from Michigan and the surrounding Great Lakes area, including Native Copper, Lake Superior Agates and Isle Royale Greenstones.

Jewelry made just for you that evokes magical memories of travels with family and friends and a tangible token of where your heart calls "home". Jewelry made with heirloom quality, sustainable and eco-friendly materials so they can be treasured by the next generations.

I am located in the Keweenaw Peninsula of the Upper Peninsula of Michigan. My home production studio is in the northwoods overlooking Lake Superior which is the reason that I named my workspace:

Superior Northwoods Studio.
