Most rings are stocked in a size 7 and can be adjusted to any size between 6-8. If you know you need a size beyond this plan ahead 3-4 weeks so we can order it in the correct size (or at least close and we can re-size after the proposal.)

No clue of her size? Ask her friend or sister-girls talk about these things! Or opt for a simple design without side stones (like a solitaire or basic three stone design) that gives full flexibility of re-sizing.
