Read the write up on Petoskey Stones in the previous post!
Here is another sample of the same, beautifully hand polished in its entirety. The first picture is in natural light with a US dime for scale, 2nd picture is in LW 365nm, the Royal Torch being held some 4 feet away to prevent the camera photometer from washing out, and finally KT took a picture with the Chinese USB led microscope to display the nice preservation of one of the coral cells at 10X in natural light. This quality of preservation in petoskey stones is common and one reason they are so collectible!
Enjoy the pictures!
