these heart charm sleeper hoop earrings are the perfect gift to show someone how much you love them. made with sterling silver, they come in a variety of colours and sizes, giving you lots of options to choose from! once you have used the first drop down menu to choose the birthstone that you want, use the second drop down menu to decide the size. the measurements given are the external diameter of the hoop and just so you know, the smaller sizes can be a bit tricky to get on. once they are on though, they'll stay there comfortably!
