Sizing Chart
Find your ring size using an existing ring or by measuring your finger. If you need a size that is not listed, contact the studio before ordering.
Measure an existing ring
Choose a ring that fits the intended finger. Measure straight across the inside of the ring at its widest point, from inside edge to inside edge. Use the diameter in millimetres to find the closest size below.
Measure your finger
Wrap a narrow strip of paper or measuring tape snugly around the finger, mark where it meets, then measure that length in millimetres. This gives the finger circumference to compare with the table below.
Finger size changes with temperature and activity. Measure when your hands are comfortably warm.
Your hands can differ slightly in size, so measure the exact finger and hand the ring will be worn on.
Wider bands can feel tighter. If you are between sizes, the larger size is generally the safer reference.
