hello, I’m hoping to get an answer here as I can’t seem to find it anywhere else. I just purchased a vintage Cartier trinity, as I wanted without exterior engraving, however I just noticed the Cartier stamp is in the gold ring which seems off to me as my previous research has led me to conclude the engraving is an has always been inside the rose gold one ( as is the case for my trinity coed bracelet purchased from the store). Perhaps someone can help me if this is a clear indicator for it not being authentic ?
Would so greatly appreciate any help
