How to measure your ring size:
1. Measure the interior diameter (mm) of a ring that fits well (on your finger of choice) - match this measurement to our table.
2. Order a ring sizer by emailing concierge@lucydelius.co
3. Book an appointment at our London showroom and one of our team will measure your finger.
