How To Measure Your Ring Size

Option 1 – Using A String Or Paper Strip

1. Use a non-stretchable string, ribbon, or thin strip of paper.
2. Wrap it around the base of the finger where you plan to wear your Aurora Ring™.
3. Mark the point where the string or paper overlaps.
4. Lay it flat and measure the length in millimeters (mm).
5. Compare your measurement to the circumference values shown in the size chart above.

Option 2 – Measure An Existing Ring

If you already own a ring that fits comfortably:

1. Measure the inside diameter of the ring.
2. Compare the measurement to the diameter column in the size chart above.
3. Select the closest matching size.

Tips For The Best Fit

• Measure your finger at the end of the day when fingers are typically at their largest.

• Make sure the ring can comfortably slide over your knuckle.

• The ring should fit securely without feeling overly tight.

• Finger size may vary depending on temperature, hydration, exercise, and time of day.

• If you are between sizes, we generally recommend choosing the larger size for additional comfort.

Recommended Finger Placement

Aurora Ring™ can be worn on any finger.

For the best overall experience, many customers prefer:

• Index Finger

• Middle Finger

• Ring Finger

Choose the finger that provides the most comfortable and secure fit.
