I hope I’m not a bother, and the information I’m asking for invaluable to me.
I’m currently working in Qatar. I just purchased a couple pearl necklaces from the local pearl hero here.
One in particular, an 18 inch black pearl necklace has peaked my curiosity.
Upon further inspection, I found 2 beads of the strand where, at the drill hole site, you can see an off-white core with the black coating edging up to this visible off-white area.
So, I tried the rub test and tooth test, and all of the pearls appear “gritty.”
My question is, should the entire pearl be black, or is the black nacre actually just the external coating?
Please pardon my ignorance, first in the form of purchasing before researching, and secondly for not knowing where else to turn for advice before bugging you.
Any help would be greatly appreciated.
Thank you for your time,
