I bought these champagne SSP 9.5mm at a trusted vendor. They were undrilled and were mostly tear dropped shaped. I had to go through for almost an hour trying to find more round ones and as blemish-free as possible. I couldn't get all with similar overtones and chose more for roundness/luster and as close in color as possible. Back story is that the previous week I picked thru all the better quality ones and these were all she had left in stock for champagnes and not alot in this smaller size or color. There are some with black pits. Can you all tell me more about it? My sister (whom I bought it for) asked me how to know they're not shell pearls or fakes. Please advise. Excuse ahead of time if pics don't attach. I tried doing it on my mobile and clicked on the full site button which gave me option to upload. May have to wait till I'm in front of computer if this attachment doesn't work. Thx.
