Gone are the days of guessing what your ring size is! This reusable ring sizer is your best tool for getting the perfect fit every time and building your ultimate ring stack.
Slide the ring sizer around your finger and make sure it's a snug fit - not too loose and not too tight. The number you read is the circumference, you can use our ring size conversion chart to check which size ring you need.
