This is a nice speciman of this coral fossil.
It has been polished on the top only. Bottom is left unpolished.
See scans.
This stone is hand polished. It is not "lacquered" like so many are.
The Petoskey stone is a fossil coral.
Condition - Very good. Nice "eyes" on this stone. Would make a very nice speciman to enjoy.
Measures - Approx. 3-3/8" x 3"x 1/2" thick.
Quality - Very good. Has very nice "eyes". Does show slight
undercut, but overall is a very showy stone.
REAL NICE HAND POLISHED STONE.
