Rings are a Gem Bazaar forte and we love them! But how to find your correct size?

This website uses UK ring sizes. If you know your US or EU ring size then use this handy chart to find your corresponding UK size.

If you don’t know your ring size, you can either buy a cheap ring sizer, (readily available from the internet) or go to a local jeweller who will be able to measure your finger and tell you.

Alternatively take a piece of wire (garden or picture wire is good); wrap it round your finger to a comfortable fit (making sure it will slip over your knuckle); cut it, stretch it out and measure it precisely. Then use this chart to find your size. If you can’t find any wire, try this with string, a measuring tape or a piece of sticky tape.
