We've got size guides for every category to make this part easy. For
necklaces, our guide shows exactly where each length sits on the neckline, so you can picture how it'll look on her before you even order. For
rings, the most reliable trick is to borrow one she already wears, one that fits the finger you're shopping for, and measure it against our ring size guide at home. If you can't pull that off, go with a category that doesn't need exact sizing, necklaces work on everyone, and
earrings are always one-size. And if anything doesn't fit perfectly when it arrives, exchanges are always free, just keep in mind that returned items need to be sent back within 30 days of the delivery date.
