Hey Doug! Thanks for reaching out. I did send you a message on Instagram as I am having a bad time posting photos to this thread. I found what I believe to be a pearl of some sort. When I found it it was in a rock bed/shell bed, not inside a creature. It did have a brown sticky substance...
What type of pearl is this? I was free diving for lobster in Puerto Rico and found what I believe is a pearl. It’s almost perfectly round, white, and has a rainbow overtone. It is around 12-14 mm. I’ve attached photos
