I just got these yesterday, so I can't attest to the long term durability of the product yet. However I will say that the little hoops that connect the chandelier part to the earring itself are welded shut, unlike many earrings where they're merely clamped together. Hopefully this means less likelihood of it slipping off. So far my nickel-sensitive skin hasn't had a reaction either. They look very elegant, and Overstock customer service was fantastic. I noticed a price drop three days after placing my order, and within 10min of initiating an online chat was refunded the difference in the form of store credit.
