I've already shipped them back to the seller. This was the auction:
https://www.ebay.com/itm/Antique-Black-Nephrite-Jade-Stone-Earrings/323222663042?ssPageName=STRK:MEBIDX:IT&_trksid=p2057872.m2749.l2649
They had an appraisal from a jeweler for over $2K but as soon as I felt them I knew they weren't gold nor were they nephrite. Felt like plastic, they were way too light. I put them under a black light and there were some scratches on the back which glowed, but that could have been polish. So I called their jeweler who said they stood behind their appraisal but couldn't tell me how they decided if they were nephrite /-: And then told me they felt different because they were higher grade nephrite than my bangle /-: So I took them to a jeweler and he went back and forth and then looked under a microscope etc . . . said the edges of the stones were red and that the "gold" setting wasn't. Thankfully the seller will refund my money . . . of course she says she paid $2K and is upset at her loss . . . I suggested sending them to GIA or Mason Kay and then going after Ralph Lauren's Estate to get her money back . . .
Ugh! That appraiser is a clown. I am
So glad you could return them, IWHLVR!
