I was eating at Sea Galley in my home town of Anchorage, AK. I didn't think much of it. I don't know how common this is, or if it has any value at all. It is white, 2, maybe 3 mm. Rough, but round. I don't know anything about pearls, but maybe someone can help tell me about my find. I guess it isn't as common as I thought when I first found it, wonder if I should have traded it to the company for a free meal or something.
