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.

Land & collecting status
Generally open to casual rockhounding
Most public-tagged spots sit on BLM, U.S. Forest Service, or other federal land where reasonable hand collecting of common rocks and minerals is allowed. Confirm posted rules and active mining claims before you dig.
Access note: This is a state-gem and heritage destination, not a dig site. Tennessee tightly regulates mussel harvest and many species are protected, so wild mussels cannot be taken for pearls. Visitors come to learn about and see the pearls at the private pearl farm and museum rather than to collect.
Public-land rules vary by agency, season, and field office. The RockHoundR app pulls live BLM, USFS, NPS, and tribal overlays so you can see exactly which agency manages the ground at this spot.
