Our two-sided soldered charms are hand soldered in our Minnesota studio, so little variations are not only accepted, but expected and add to the charm of the piece. Materials: glass, paper, lead free + jewelry grade solder. Dimensions: Soldered charm 1/2" x 2". Complete Necklace option includes a 30" aluminum ball chain with ball chain connector and a freshwater pearl. Please note: This listing is for one piece only. The photos show both the front and back side of the charm. You can purchase the complete necklace, or you can purchase just the charm. We sell chains separately to give your customers the option to mix and match multiple charms on their necklaces and build their own necklaces.
