Long Island Clam Bake
I was out to a clam bake on Long Island and had a plate of steamed clams. I noticed in one of the clams a dark spot at first thinking it was a dark muscle in the clam and as I poked at it. It was hard so I worked it out of the clam.
I started to research what it could be and found similarities on line so I tried to take to a jeweler but they have never seen anything like it and possibly believe it to maybe be onyx but how do I find out?
