HOW TO CHECK YOUR RING SIZE:
Wrap a piece of string or a strip of paper around your ring finger. Make sure you can slip it comfortably off your finger over your knuckle. Use a ruler to measure the length of the string or paper. This is your finger's measurement.

MOON ZENITH RING SIZES:
As SJ source rings from Mexico, our ring sizes are the same as Mexico. Please see the ring size conversion chart above if required.

HINT:
Your fingers swell in the heat, so you will get a more accurate measurement when your hands are warm, not cold.

CHEEKY (BUT NICE) HINT:
If you are purchasing a ring as a gift and you want to keep it a surprise, secretly measure one of their rings.
