Greetings, this is my first post. I asked Google about how to find out about a pearl and this was suggested by a Yahoo answers question someone else had asked. Anyway, I was eating the Westport Seafood Feast at the Crab Pot in Seattle and bit into this (my teeth are okay) when I was eating one of the clams. All of their clams and mussels are classified as saltwater. Anyway, the picture is attached. I was curious if this is a pearl, and if so, what kind it might be. It has a purplish hue. It is small as the paper it is on is a standard business card. As it is small, I know it is likely to be not worth much, but I'd be happy to know such information
