Elegantly wire-wrapped stone pendants feature stone unique to the Keweenaw Peninsula and the Lake Superior and Copper Country regions.  Some of the favorites are Datolite, Thomsonite, Prehnite, Firebrick, Mohawkite, and Copper Replacement Agates.  Also see our featured category for Lake Superior Agate pendants and the Greenstone pendants.  The Copper Country in the northernmost part of Michigan's Upper Peninsula yields some of the most unique gemstones, each related in its own way to the copper origins.  Our Firebrick jewelry reflects the historic copper industry that created such a mining rush in the 1800's.  Our Datolite, Mohawkite, and Copper Replacement Agate jewelry are made with gemstones not found anywhere else on earth in these forms, and are unique to very small localities where they originated.  Families of miners treasure our jewelry reminding them of their family involvement in certain mines.  Prehnite can be pink or green and may have streaks or bits of copper imbedded in the stones, and may be found on old mine dump piles or on beaches.  Thomsonite is primarily found on the North Shore of Lake Superior in Minnesota, but some good stones have also been found in the Keweenaw Peninsula.  We make our favorites into quality jewelry with great heirloom value.

    Prehnite stones from the Lake Superior area can vary from apple green with copper inclusions, to pink and dark green similar in appearance to Thomsonite, in fact the pink and green stone used to be referred to as UP Thomsonite.  Prehnite can also be almost brown and white.  Pebbles found in the Keweenaw Peninsula may be turned into beautiful jewelry pieces. Nuggets can be found in the water, on the beach or even in hills overlooking the lake, where they look totally different from their polished version.  We sort through lots of stone to select interesting pieces for our jewelry which is then elegantly wire wrapped in 14/20 yellow or pink gold and tarnish-resistant argentium silver. Apple green prehnite with bits of copper laced through it, or pink pebbles, both make terrific reminders of the Copper Country.
