How to Measure & Notes

Wrap a strip of paper or thread around the widest part of the finger you’ll wear the ring on. Mark where it overlaps,
then measure that length—this is your finger circumference. Compare it with the chart to find your ring size.

  • Finger size can vary slightly with swelling and time of day. Please consider this when choosing your size.
  • Sizes may differ between hands; the dominant hand is often slightly larger.
  • For wide bands, we recommend choosing one to two sizes up.

For a detailed explanation of our grading standards with visual examples, please visit our Pearl Grading Guide.

While we cannot guarantee an exact match because pearls are a natural material, we will select a piece that is as close as possible to your requested color tone (this is only possible for items with multiple units in stock).

No under normal wear. Gently wipe after use and store away from heat, humidity, and direct sunlight.

Always wipe your pearls after wearing them - this is the most important step. As shown in the video, gently rub each pearl with a soft cloth (microfiber or pearl polishing cloth) to remove oils and perspiration. Avoid paper tissues and water washing.

Put on your pearls last, remove them first. Keep them away from perfume, hairspray, cosmetics, sunscreen, household cleaners, and acidic foods.

Store separately in a soft pouch or jewelry box, away from direct sunlight and heat.

Remember: A few seconds of care after each wear keeps your pearls beautiful for generations.

Six-month warranty from delivery. In-warranty repairs are free (shipping paid by the customer); fees may apply depending on condition.

A branded case and a quality guarantee certificate are included; packaging may vary by item.
