NWT Set of 3 pair, 925 Sterling Silver Earrings purchased from Icing. 1 pair gemstone, 1 pair silver balls and 1 pair pearlized. I purchased but did not try on; both backings (silver and rubber) are attached to each stud. Slightly smaller stud than average, perfect for all ear piercings and can be mix and matched very easily! Any questions, please ask!
