· Sobre la moissanita
Buying a moissanite ring online is exciting, but the one number that decides daily comfort is your ring size. Get it wrong and the piece you love becomes a drawer item. This guide walks you through measuring at home, reading a ring size chart, and the small rules that stop most sizing mistakes. You can also browse ready-made styles at https://www.moissaniteluma.com/en/rings/ before you decide.
How do I measure my moissanite ring size at home?
The paper-strip method is the easiest start. Wrap a thin strip of paper or string snugly around the base of the finger you will wear the ring on, mark the overlap, then measure the length in millimeters. That length is your finger circumference. A second method is to measure the inner diameter of a ring that already fits that finger by laying it on a ruler. For the most reliable result, visit a local jeweler for a quick mandrel reading. Use at least two of these methods and compare the numbers.
Does finger temperature change my ring size?
Yes. Fingers swell in heat and shrink in cold, and they are often larger in the afternoon than first thing in the morning. Measure at room temperature, late in the day, and away from exercise or a salty meal. If your two readings differ, trust the larger one. A size taken on a cold morning can leave a ring that feels tight by evening.
Should I size up or down for a wide band?
Wide bands sit more snugly than thin ones, so the same finger often needs a half size larger for a band wider than about five millimeters. Slim tapered bands, which are popular in current solitaire styles, usually match your true size. If your knuckle is much larger than the base of your finger, go up a half size so the ring clears the knuckle without spinning at the base.
Which ring size system should I trust when I order online?
Size systems differ by region. A US size, a UK letter, and an EU number do not mean the same thing, and a ring size chart converts between them using inside diameter and circumference. Always confirm which system the seller lists before you commit the number. Many buyers assume one size fits every market, then receive a ring that is off by a step or two. When in doubt, ask the seller to confirm the system in writing through the contact page at https://www.moissaniteluma.com/en/contact/.
How do I confirm the size is right after the ring arrives?
Check the fit at room temperature. The ring should slide over the knuckle with slight resistance and sit at the base without sliding off or leaving a deep mark after an hour. If it spins freely or feels like a tight band, the number is wrong. Compare the delivered piece against your paper-strip reading before you wear it out.

What if I order the wrong size - can it be resized?
Many moissanite rings in solid metal can be resized, but not all. Settings such as full eternity bands, heavily set styles, and some channel-set designs are hard or impossible to adjust without rework. Confirm the resizing policy in writing before you pay, because the cost and timing vary by design. A correct size before order is always cheaper than a resize after.
What should I verify with the seller before I order?
- Applicable scope: This checklist covers finger-measured rings such as solitaire, halo, and everyday bands. It does not replace a professional fitting for joints affected by arthritis or swelling. - Lead time: Ask your seller for the current production window, because made-to-size pieces are cut only after you confirm the number. - Minimum order: Confirm the smallest order quantity with your seller; some studios set a floor while others accept a single ring. - Samples: Request a plastic ring sizer or a loaner band in your best-guess size so you can feel the fit before the final number is locked. - Failure conditions: A size reading fails when taken on a cold finger, right after exercise, or using a stretched old ring as the reference. - Test methods: Use the paper-strip circumference method, an existing well-fitting ring inner diameter, and a local jeweler mandrel as three independent checks. - Parameter meaning: Diameter is the straight across-the-inside width; circumference is the full finger wrap. A difference of about one millimeter in diameter can shift the size by roughly a full step. - Inspection and after-sales: On arrival, slide the ring over your knuckle at room temperature and confirm the written resizing policy, because some settings such as full eternity bands are hard to adjust. - Certificate note: If your seller provides a certificate, treat it as a description of the measured stone; it does not certify resale value or long-term worth.
How should I remember this when I order?
Get your ring size from two home methods at room temperature, size up a half step for a wider band, confirm the regional size system in writing, and verify the resizing policy before you pay. Treat any certificate as a description of the measured stone, not a promise of value. Do these steps and the ring you receive will fit the day it arrives.
