Size Guide

Last updated: July 14, 2026

A refined fit begins with a thoughtful measurement. This guide is designed to help you choose a comfortable size for Montlune Crystal jewelry, including beaded bracelets, chain bracelets, necklaces, rings, earrings, anklets, and adjustable pieces.

General Notes

  • Jewelry fit is personal. If you prefer a closer fit, choose the exact measurement closest to your body size. If you prefer a relaxed fit, choose a slightly larger size.
  • Natural gemstones, crystals, pearls, and handmade details may vary slightly in size, shape, color, and texture.
  • Measurements listed on product pages are approximate and may vary slightly due to hand-measuring and material characteristics.
  • For pieces with extension chains or adjustable closures, the listed size usually refers to the wearable range.

Bracelet Size Guide

How to measure your wrist

  1. Wrap a soft measuring tape around the part of your wrist where you would normally wear a bracelet.
  2. Keep the tape close to the skin, but not tight.
  3. If you do not have a soft measuring tape, use a piece of string, then measure the string with a ruler.

Recommended bracelet fit

Fit Preference Recommended Size
Close Fit Wrist measurement + 0.5 cm
Comfort Fit Wrist measurement + 1.0 cm
Relaxed Fit Wrist measurement + 1.5-2.0 cm

For beaded bracelets, a slightly relaxed fit is often more comfortable, especially when the beads are larger or more structured.

Common bracelet length reference

Bracelet Length Suggested Wrist Measurement
14.5 cm Approx. 13.5-14.0 cm wrist
15 cm Approx. 14.0-14.5 cm wrist
16 cm Approx. 15.0-15.5 cm wrist

Necklace Size Guide

Necklace length can vary depending on body frame, neckline, pendant size, and styling preference. The same length may sit differently from person to person.

Length Typical Position
35-38 cm Choker or close-to-neck fit
40-42 cm Near the collarbone
45 cm Classic everyday necklace length
50-55 cm Below the collarbone, relaxed styling
60 cm and above Long necklace or layering length

Pendant necklaces

For pendant necklaces, please consider both the chain length and the pendant drop. A pendant may make the overall visual length appear longer.

Adjustable necklaces

If a necklace includes an extension chain, it can usually be worn across a range of lengths. Please refer to the product page for the exact adjustable range.

Ring Size Guide

How to measure your ring size

Option 1: Measure an existing ring

  1. Choose a ring that fits the intended finger comfortably.
  2. Measure the inner diameter of the ring in millimeters.
  3. Compare the measurement with the size chart below.

Option 2: Measure your finger

  1. Wrap a strip of paper or string around the base of your finger.
  2. Mark the point where it overlaps.
  3. Measure the length in millimeters. This is your finger circumference.

Measurement tips:

  • Measure your finger at the end of the day when it's at its normal size; cold fingers can make your measurement smaller.
  • If you are between two sizes, we recommend choosing the larger size for comfort, especially for wider bands.
  • Ring sizing can vary slightly between different brands and measuring methods.
