thanks everyone, attempting to get better photos today. still surprised at it's size myself. after continued research haven't came across one of this size.
Thanks for the add to this board, much appreciated.
I'm attempting to find value of a pearl that has been in the family for years. It was found off the coast of Cape Cod. Taken to a jeweler once..... it was measured at 18 mm x 10.9 mm and 27.5 cts weight? I would describe it as a button...
