How to Measure at Home
Measure at Twilight
Fingers naturally expand slightly in evening ambient warmth. Measure when hands are comfortably temperate for true baseline accuracy.
Account for Knuckle Clearance
If your knuckle is noticeably broader than the base of your finger, select a half-size larger to glide smoothly into position.
Wide Band Compensation
Bands broader than 4mm fit more snugly than delicate solitaires. We recommend ordering a half-size up for eternity and bridal stacks.
Bespoke Complimentary Sizing
Every bespoke creation from Aurum includes one complimentary resizing within 90 days of international delivery.
