Sick of the same old jewelry all the time? Change it up with this monthly box. Start by creating a wish list on their site of jewelry you love. They'll send you 3 fun pieces by hot designers including Aster, Ava Rose, House of Harlow 1960, and Kate Spade. You keep and buy what you like (the $21 monthly fee gets applied as credit to any purchase) and send back the rest.
