huh, never heard that one tater140, how big was the marble?
Unglegillhunter, it was a really easy process. All I did was pop the whole eye out and boiled it, no exact science or anthing, don't remember how long it boiled but couldn't be too awful long. Then I just popped or dug the pearl out and didn't need any finishing work. It was round and small like a bead depending on size of walleye.
I'll have to boil a few sometime just to show my son and son in law.
