Size guide
The quickest way to the right size is a ring that already fits the finger you’re buying for. If you don’t have one, a strip of paper works. Not sure? Choose your best guess: we confirm the size in your proof, and offer one free resize where the design allows.
Rings
- From a ring that fits. Measure straight across the inside, edge to edge, in millimetres. Find the closest diameter below.
- With paper. Wrap a thin strip around the base of the finger, mark where it overlaps, and measure the length. That’s the circumference.
- Measure at the end of the day, when fingers are a little larger, and make sure it slides over the knuckle.
- Wider bands fit more snugly. For 6 mm and above, many people go up half a size.

Print this page at 100% scale (turn off “fit to page”). Check the 50 mm line with a ruler first. Place a ring that fits over the circles: the right size is the circle that matches the inside edge.
Bracelets
Bracelet size is the inside circumference of the bracelet. Measure your wrist snugly and add 0.5 in (1.3 cm) for a comfortable fit. Heirloom bangles need to pass over the hand, so if your hand is broad for your wrist, tell us in your order or book a sizing call.
