Do any of you all noticed any slight tarnishing on your Cartier earrings? I have a pair of the love studs (the pair) in yellow gold. On the back of the earring is a slight garnish as well as the back of the earring backings. The front and post of the earrings arrant tarnished at all. Just wanted to ask if this is normal or if anyone has experience it? I tried cleaning it but it hasn’t worked. I usually let them soak in hydrogen peroxide for a few minutes the wash with some dawn.
