In Florida there are two big draws for treasure hunting: silicified coral and buried treasure complete with gold doubloons and pieces of eight. Here are some of the best areas for finding treasure, in addition to some useful resources.
The famous silicified coral, first found in the Tampa Bay area around 1825 is the only gemstone of note from the State. Since its discovery in Tampa Bay, the agatized coral also has been found at Tarpon Springs, south of New Port Richey, near the town of Kathleen, and along the banks of the Suwanee River in Hamilton, Columbia, and Suwanee Counties. The material is found in two forms: as geodes, which represent partial replacement of coral; and as solid pieces which represent total replacement. It can be blue, red, brown, amber, white, black, or a combination of these colors.
