Tennessee River & Streams: Pearl Rockhounding in Decatur County, Tennessee

Updated July 2026

The Tennessee River is the home of the Tennessee River pearl, the official state gem, a natural freshwater pearl formed in the river's native mussels. Upstream on Kentucky Lake, the Birdsong Creek embayment hosted North America's only cultured freshwater pearl operation, founded by John Latendresse. This reach of West Tennessee is the setting for that state-gem story. Reported finds include pearl. Below: coordinates, access notes, nearby spots, and trip-planning links.
