Ring Sizing

Ring Sizing:

Ring sizing can vary around the world—different countries and regions use different numbering or lettering systems. To help you find the right fit, you can use the conversion chart below to match your ring size to our standard sizing.

If you’re unsure of your ring size, we recommend visiting a local jeweller or jewelry store to have it measured accurately. It's the most reliable way to ensure a perfect fit. If you need a band larger than a size 20 we can likely accommodate that too, just send us a message to confirm.

Please note that wider bands tend to fit more snugly than thinner ones. Be sure to take this into account when selecting your ring size, especially for designs with a thicker profile. 

If you have any further questions or need help with sizing, feel free to reach out—I’m happy to guide you through the process.
