Such a staple for any jewellery collection and a great pair of starter earrings, these studs are made from sterling silver with a plain capped ball design that measures 3mm in diameter. Stamped with a 925 metal mark, the earrings have a front to back distance of 1.3cm with butterfly backs securing them in place. Together as a pair, they weigh just less than half a gram. Made From Recycled Sterling Silver
