• Verify the material is natural calcium carbonate, which will feel cool to the touch and have a distinct weight compared to plastic imitations.

• Confirm the origin as United States freshwater sources, typically harvested from riverbed environments.

History of Freshwater Mussel Shells

During the late 19th and early 20th centuries, freshwater mussels were the primary source for the pearl button industry in the United States and Japan. Harvesters would collect these bivalves from riverbeds, and the inner nacre, or mother of pearl, would be stamped into blanks to create durable, lustrous buttons before the advent of plastic.
