Ring Size Guide & Jewelry Care Tips

Ring Size Guide — US Sizing

Measure your finger at the end of the day when it is at its largest. If you are between two sizes, always choose the larger size for comfort.

US Size Circumference (mm) Diameter (mm)
5 49.3 mm 15.7 mm
6 51.9 mm 16.5 mm
7 54.4 mm 17.3 mm
8 57.0 mm 18.1 mm
9 59.5 mm 18.9 mm
10 62.1 mm 19.8 mm

How to Measure Your Ring Size at Home

  1. Wrap a thin strip of paper or a flexible tape measure around the base of your finger.
  2. Mark where the paper overlaps and measure the length in millimeters — this is your circumference.
  3. Match your measurement to the table above to find your US size.
  4. For wide bands (like eternity rings), we recommend sizing up by half a size for the most comfortable fit.

Expert Jewelry Care Tips

Daily Care

  • Wipe after every wear: Use a soft, lint-free cloth to remove natural oils and residue after each use.
  • Remove before activities: Always remove your ring before swimming, exercising, applying skincare products, or using cleaning agents.
  • Put jewelry on last: Apply perfume, lotion, and hairspray before putting on your jewelry to minimize chemical exposure.

Deep Cleaning

  • Ultrasonic cleaning: Moissanite is fully safe for ultrasonic cleaners — use once a month for a professional-level sparkle.
  • Home soak: Soak in warm water with a drop of mild dish soap for 10–15 minutes, then gently scrub with a soft toothbrush and rinse thoroughly.
  • Avoid harsh chemicals: Chlorine, bleach, acetone (nail polish remover), and ammonia-based cleaners will damage the rhodium plating over time.

Storage

  • Store separately: Keep each piece in its own velvet pouch or the original gift box to prevent scratches.
  • Avoid humidity: Store in a cool, dry place away from direct sunlight and moisture.
  • Travel smart: Use a dedicated jewelry travel case with individual compartments when traveling.

Rhodium Plating Maintenance

  • Rhodium plating on sterling silver typically lasts 1–2 years with daily wear.
  • Signs of wear include slight yellowing or loss of the bright platinum-like finish.
  • Moissanite Shine Lifetime Upgrade Program covers rhodium re-plating — contact our support team anytime to arrange a refresh.

Moissanite-Specific Facts

  • Moissanite ranks 9.25 on the Mohs hardness scale — second only to diamond — making it highly resistant to scratching.
  • It will never cloud, change color, or lose its fire over time.
  • Every Moissanite Shine stone is D Color, VVS1 Clarity, and GRA Certified for guaranteed quality.
