The Sól Na Rany signets come in three universal sizes:

Signet rings size
Ring inner diameter (mm) 19 20 21
Ring inner radius (mm) 9.5 10 10.5

Measuring the inner diameter of the ring in millimetres (mm) is a convenient way of selecting the right size for you signet. All you need to do is measure the inside diameter of your the ring you already own and compare it to our sizes.

If the measurement falls between two sizes, we suggest a larger one.

Each of our signet rings is hand-finished, therefore their size may slightly vary from sizes given above.
