Thank you for viewing. This item is an authentic Chrome Hearts Cross Ball Stud earring. I purchased this about 2 years ago from a used Chrom Hearts retailer, and it is guaranteed to be authentic. I haven't used it much, so the frequency of use is low. This is a used item, so I will only sell it to those who understand this. There is a 14K hallmark. I apologize for the poor visibility due to the photos being taken with a mobile phone. Please contact me if you have any questions.
