Ring Size Guide

The most accurate way to determine a ring size is by visiting our studio and having your finger measured by our jeweller.

If that's not feasible, here are a couple of alternative suggestions to finding out a ring size :

  • Check their jewellery box! Look for a ring they already own and have it measured. While it may not be entirely precise due to ring sizes vary from finger to finger, it's a great starting point.

  • Seek assistance. Reach out to friends or family members to see if they have any insights or have discussed ring sizes before. If not, perhaps they can discreetly gather information without raising suspicions.

If you're unable to obtain an accurate size, don’t worry, we offer a complimentary resize with every Michelle Oh ring purchase. This service can be used at a later date, whenever necessary.
