round stone with holes

[nathan007]

Hi, found the attached item on the river shore in somerset county md. It appears to be made of stone with a hole in the middle and four holes going from the outer part to the center. Does anyone have any ideas? Thanks!

Looks like a cog of some sort, do the small holes appear to be threaded?

Mike, I can't see any threads. Thanks!

are you sure about it being stone.metals will encrust with mineral deposits while in the water.

 

[nathan007]

I'm nearly positive that it is stone because i accidentally chipped it.

Heavily encrusted metal object.

Saltwater silver turns out the same way.

once metal has been encrusted long enough its metal becomes replaced with local minerals,think fossils except in a hurry.I would guess NO WAY it was always stone but I believe you that it is mostly now.This is my simple guess.If it was made from stone originally than it is simply a"one of a kind"piece imo

I sure hope it gets solved,has peaked my interest
