Counterfeit in 10k....genuine cartier is no less than 18k. This one is missing the notches on the nail back, but tests 10k like it's marked. Weighs 15 grams, so its a nice scrapper !!
I quickly clip and scrap any counterfeit jewlrey. It's how it has to be to be legally safe...I guess they could actually sieze this from you technically. But clip it into pieces with pliers and it's scrap gold.
