How to Measure Your Ring Size

Method 1: Measure an Existing Ring (Recommended)

Select a ring that already fits comfortably on your desired finger.
Use a ruler to measure the inside diameter (the distance straight across the inside of the ring) in millimeters.
Match your measurement to the "Inside Diameter" column in our chart above.

Method 2: Measuring Your Finger

Wrap a flexible measuring tape or a thin strip of paper around the base of your finger.
Mark the exact spot where the ends meet and measure that length in millimeters.
Match this length to the "Circumference" column in our chart above.

Pro Tips for the Perfect Fit ✨

Timing matters: Measure your finger at the end of the day when it is slightly larger.
Caught between sizes? We always recommend sizing up for the most comfortable fit.
Wider bands feel tighter: If you are choosing a thicker ring style, consider going up half a size.
Still unsure? We’re here for you. Reach out to our team at support@cofuze.com for personalized sizing advice.

Note: UK and Australian ring sizes are the same. US and Canadian sizes are also identical.

I bought this for my engagement party. I usually worry that large center stones will catch on my dresses, but the prongs on this moonstone are polished perfectly smooth. It sits relatively low on my finger, and the side stones give it a beautiful balanced weight without feeling bulky.

Your Questions, Answered

Details about cut and wear.

How do I choose the right ring size?

We recommend having her finger sized by a local jeweler for the most accurate fit. Alternatively, you can use our printable sizing guide. If you happen to guess wrong, do not worry—we offer hassle-free size exchanges within 30 days.

How do I care for my moonstone and sterling silver ring?

Gently wipe the moonstone and silver band with a soft, lint-free cloth after wear. To maintain its brilliant polish, remove the ring before showering, swimming, or using harsh cleaning chemicals, and store it in the provided velvet pouch.

Is the moonstone natural?

Yes. We use genuine, natural milky blue moonstones. Each ring is accompanied by a third-party appraisal certificate to guarantee the authenticity and quality of your gemstone.

Is this ring suitable for daily wear?

Absolutely. The ring features a low-profile design and smoothly polished prongs that will not catch on everyday clothing. However, as moonstone is a natural gem, we recommend removing it during heavy manual tasks to prevent accidental impact.

What if she prefers a different style?

We want her to absolutely love it. That is why we offer a 30-day, no-questions-asked return and exchange policy. If the design is not her perfect match, simply contact our support team to arrange a smooth return.
