Still not sure what your ring size is? No worries, Moon Child! We’ve created a step-by-step guide for measuring your fingers the old fashioned way.
  1. Gather a pen and a piece of non-stretchy string or paper that’s 6’’ long and 1/4’’ wide.
  2. Wrap your string around the finger you’d like to buy a ring for. Make sure it’s snug, but not tight, on the exact area where you’d like to wear the ring.
  3. Notice where the string overlaps to create a circle, then mark it at this point.
  4. Use a ruler or measuring tape to measure the string or paper in millimeters.
  5. Find your measurement on the “Inside Diameter” column, then check to see which US & Canada size it corresponds to.

Additional Sizing Tips

Your fingers can shrink and expand when exposed to hot and cold conditions. The best time to measure your finger is when you’re at a comfortable room temperature. If your knuckle is larger than your finger’s base (that’s normal!), measure both your knuckle and your finger base. Then, choose a size in between. This will allow your Moonstone ring to glide on your finger with ease and still rest snugly in place.

If you’re still unsure about your ring size or something doesn’t seem right, fear not. The drawing below showcases general size ranges for each finger.
