Sizing
Rings are made in your size. Measure with a jeweller's ring gauge on the finger you mean, late in the day when hands are warmest; if your knuckle is bigger than the base of your finger, the knuckle decides.
Signets and wide bands sit snug, so go a half size up from a slim band. The terrace band is 4.6mm wide and the fieldstone and bark bands 7mm; the wool twist and the wheat band are slimmer and true to size.
The shepherd's cuff is open underneath and eases on over the side of the wrist; tell us your wrist and we make it to that.
