Thanks. I returned the MOP at the boutique today and the sales associates were quite nice to me. I will do the metal health patch test and see what I am allergic to. I did get rashes again when I tried the two pieces of gullioche and carnelian 10 motif today.. no redness with the agate 10 motif. I asked if there was any glue or wrapping with the pieces. They said no they only clean with steam and water.Up until my mid 20s I was allergic to 24k, WG and silver in my piercings. I could wear them if not in piercings. Then in my 40s I tried piercing again and this time I wore only platinum earrings for 4 years and used sterile sea salt spray. Then I switched over to WG and was fine. I guess I’m trying to say don’t push it. People can develop allergies to things they previously were not allergic to. I would stick to the pieces that have proven to be inert to you. Your health is more important than any jewelry.
I asked my doctor and he told me, he doesn't think I'm allergic to MOP or the stones. It is most likely the alloy.
