FINDING YOUR PERFECT FIT


MEASURING YOUR SIZE
OPTION 1 — USE A RING YOU OWN
[Most accurate DIY method]
Grab a ring that fits the desired finger.
Measure the inner diameter in mm and match it to our size chart.
If possible, use a calliper for precision.
OPTION 2 — STRING METHOD
Wrap a string around your finger.
Mark where it overlaps and measure the length in mm.
Match it to the chart.
OPTION 3 — LOCAL JEWELLER
[Most accurate overall]
Visit a jeweller for a quick measurement.
Takes seconds and removes all guesswork.
TIPS FOR ACCURACY
- Measure at the end of the day
- Avoid measuring cold fingers
- Consider your knuckle size
- Between sizes → size up for thicker rings
- Fingers vary between hands
FIND YOUR LENGTH
Use a string, cord, or chain to see how the piece will sit on your body.
HOW TO MEASURE

- String can stretch.
- Avoid wrapping too tightly.
