See below for a conversion ring sizing chart if you live abroad and know your size. If you don't know your size we always recommend getting it professionally sized at your local jewellers. In case that's not an option we have ring sizers that you can order from us so you can do a test beforehand. See below. Use this ring sizer to determine your correct finger size. it is a UK ring size system.
Tip: the ring should go in smoothly and offer some resistance as you pull it out.
