About 1 year ago i found a pearl in my shell driveway.I measured it, it is about 18mm. It is not perfectly round and you can see where it was attached to the shell on the bottom. It is a natural or baroque pearl, its color is orient, which means it is multicolored. I to would like to sell this pearl,but it is hard to find anyone who knows about pearls or their value. Please let me know what you think.
