Hi. I am a total pearl newbie and found the forum but have not been confirmed by some administrator, I've been waiting days, the first time didn't work so I re-registered. I saw the photo of the shimmery grey/silver pearl you use with your postings. WHAT IS THAT? I have a ring with a 17 mm pearl similar to yours that I cannot identify. It is from an estate, and I sell on consignment on eBay for antique dealers and some of them don't know pearls from a hole in the ground. I want to be accurate in my listing. My pearl is almost the same color as yours, but the head sticks up more, and it's 17 mm in size. I have photos but don't know how to post them. can you help? Michele
