Ring Size Guide
Finding your perfect ring size is simple. Follow our expert guide to ensure a comfortable, beautiful fit for your fine jewelry.
How to Measure Your Ring Size
Use an Existing Ring
Place a ring that fits well on a ruler and measure the inside diameter in millimeters. Compare this measurement to a standard ring size chart to find your size.
Paper or String Method
Wrap a thin strip of paper or string around your finger at the base. Mark where it overlaps, then measure the length in millimeters. Divide by 3.14 to get the diameter.
Visit a Professional Jeweler
For the most accurate measurement, visit a professional jeweler who can size your finger with precision tools. This ensures a perfect fit for your investment piece.
Expert Tips for the Perfect Fit
Important considerations
- Knuckle fit: Your ring should slide over your knuckle comfortably but fit snugly at the base of your finger.
- Time of day: Measure your finger at the end of the day when it's slightly larger, as fingers can swell throughout the day.
- Temperature matters: Cold temperatures can shrink your fingers by up to half a size, while heat can expand them.
- Half sizes: If you're between sizes, we recommend choosing the larger size for comfort, especially for wider bands.
- Band width: Wider bands fit more snugly than thin bands, so you may need to go up half a size for bands over 6mm wide.
Finding a Ring Size Secretly
- Borrow a ring they already wear on their ring finger and trace the inside circle on paper, or bring it to a jeweler for sizing.
- Ask their close friends or family members who may know their ring size from previous jewelry purchases.
- If you're unsure, choose a slightly larger size. Rings can be sized down more easily than sized up.
- Consider purchasing a ring sizer tool online and casually suggest trying it together as a fun activity.

Frequently Asked Questions
What if I'm between two sizes?
We recommend choosing the larger size for comfort. A ring that's slightly loose is more comfortable than one that's too tight. Keep in mind that wider bands typically require a larger size.
Can rings be resized after purchase?
Most rings can be resized, though some designs with intricate details or certain metals may have limitations. Contact us to discuss resizing options for your specific piece.
Do fingers on different hands have different sizes?
Yes, it's common for fingers on your dominant hand to be slightly larger. Always measure the specific finger where you plan to wear the ring.
How accurate is the paper method?
The paper or string method can provide a good estimate, but for the most accurate measurement, especially for fine jewelry investments, we recommend visiting a professional jeweler or contacting our team for a complimentary ring sizer.
