Jewelry Size Guide & Chart

To ensure that your unique diamond or gemstone ring fits perfectly, check our ring size guide before placing your order. While our fine jewelry necklaces and bracelets are a bit more flexible with sizing, it’s still important to consult a jewelry size chart to ensure that your new piece meets your personal preferences. If you’re still not sure about your size, we’re happy to provide one-on-one assistance.

How to Find Your Ring Size

A tape measure

Finding your ring size at home is a breeze! All you need is a thin piece of paper or string, scissors, and a tape measure.

  1. Wrap the material around the base of your finger, leaving a tiny bit of room (for sliding the ring on and off).
  2. Cut or mark the point where the end of the material completes the circle.
  3. Measure the length of the material.
  4. Compare the length to our ring size guide below.

How to Find Your Necklace Size

Using this jewelry size chart is even easier than using our ring size guide, as you only need to consider the actual measurement itself.

  1. Place a sewing tape measure or any long household item, such as a piece of string or even a phone charger or headphones wire around your neck.
  2. Connect the two ends at the location where you want the necklace to sit.
  3. Cut or mark the point where the end of the material completes the circle.
  4. Measure the material.
  5. Choose a necklace size that’s closest to the measurement.

Typical Necklace Length Styles:

  • 12”: Tight, choker fit
  • 14”: Falls around the neck’s base
  • 16”: Falls around the collarbone
  • 18”: Most common size
  • 20”: Falls right above the cleavage

How to Find Your Bracelet Size

Finding your bracelet size is similar to using the necklace or ring size guide above.

  1. Measure your wrist (using the same methods above), making sure to leave enough room to slide it on or off (for bracelets without clasps).
  2. When measuring, consider your preferred tightness/looseness.
  3. Select a unique bracelet with the closest measurement.
