Many people are familiar with the lapidary material and cabochons from Indonesia. Not as many are familiar or aware of the material from Florida. In this case the Tampa Bay Florida area. These coral fossils are from 22-26 million ago and have been silicified. (The Florida Natural History Museum's invertabrate professor is co-authoring a paper that narrows the time period).
The local lapidary club is open again so thought I'd share some of my amateur pieces and the raw material I've found.
