Long term TSC fans will remember that we bought a box of Agatized fossilized coral from an American rockhound. He sent us six nodules to cut and this piece as an example of what we might find inside. So far I have lost money on the lot. There is one piece listed here with both halves which fox hand polished some time last year. Otherwise, we only have another single nodule which came from the lot.
To get this, he had to pick it up off the seabed. It's pretty special stuff from the sea near Florida. It's really cool material to work with and nobody can say Thier rock collection is complete without it.
