Ring Size Guide
We understand that finding the perfect fit for your ring can be tricky when shopping online. To help, we’ve put together this easy-to-follow guide to ensure you choose the right size with confidence. Please read carefully to make sure your new ring fits just right!
1.Why the Same Size Can Feel Different?
Even if rings are marked with the same size, the fit can feel different depending on the band width. Here’s why:
Narrow Bands (below 2mm)
These tend to feel slightly looser because they press less against the finger. Most of our women’s rings feature narrow bands.
Wider Band (over 2mm)
Wider bands or enhancer bands cover more of your finger, often making the same size feel tighter. If you’re considering a wider band or an enhancer band, consider going up by ¼ to ½ size for a more comfortable fit.
In summary: Narrow bands feel looser; wider bands feel snugger.
2. What If the Size Isn’t Right?
Sometimes resizing isn’t an option, or it may not be the best choice for your ring. Here’s what you need to know:
Limitations:
Eternity bands and intricate designs may not be resized without damaging the setting.
Risks:
Significant resizing may weaken the structure or loosen stones, especially in side-stone rings.
Alternatives:
If resizing isn’t possible, consider using ring guards, sizing beads, or requesting an exchange (subject to a 35% restocking fee for returns or exchanges).
3.How to Measure Your Ring Size?
You can measure your size at home, or visit a jeweler for precise measurements. Here are the most common methods:
At Home
Measure an existing ring
Use a ruler to measure the inside diameter of a well-fitting ring. Send us a photo if you’d like confirmation.

Inner Diameter

Band Width
- Metal Ring Gauge
This provides a realistic fit by allowing you to try rings on. Make a note of the marked size. Plastic ring sizer
Slide it onto your finger—make sure it’s snug but can still rotate. A photo helps us advise you better.Finger circumference method
Wrap a strip of paper or string around your finger, mark the overlap, and measure the length. This method is less precise, so we recommend measuring multiple times and providing your height/weight for reference.
At a Local Jeweler
This is the most reliable option. Just ask them about the band width they use, as narrow and wide bands can feel different.
Helpful Tips for the Best Fit
Measure at different times of the day: Fingers tend to swell in the evening or after exercise.
Measure multiple times: Consistency reduces errors.
Avoid extreme temperatures: Cold temperatures can shrink your fingers, and heat can cause swelling.
Consider long-term changes: If buying a gift, keep in mind that weight changes can affect finger size over time.
