Black De Ville jewellery uses standard jewellery sizing however due to the hand made nature of the pieces the sizing can slightly differ. If the wrong size is ordered and the piece requires a resize a fee of $50 applies. If you need a specific size please contact us at 


All sizing is based on the internal ring diameter (across the middle). For any other sizing questions please do not hesitate to contact.

Small - 18mm
Medium - 20mm
