so i sold a hermes CDC bracelet on ebay. i bought it from a reputable reseller (jemz n jewels). i didn't like the color once i saw it irl so decided to sell it. now the buyer is claiming it's fake simply because the stud is slightly crooked (i did not notice this and neither did the reseller i bought it from). i wanted to get the bracelet authenticated here but they won't authenticate closed auctions. the buyer opened a dispute. any suggestions on how to deal with this?
