Size Guide

Every product page lists its sizes: chain lengths in inches, and pendants, hoops and earrings in millimeters. Here's how to choose.

Necklace lengths

  • 14 in: sits close to the base of the neck, like a choker.
  • 16 in: sits at the collarbone. Our most popular length for a single necklace.
  • 18 in: falls just below the collarbone. Easy to wear with most necklines.
  • 20 in: falls a little lower, above the bust. Great as the longest layer.

Layering tip: pick lengths about 2 inches apart, such as 16 and 18 in, so each chain sits on its own. Some necklaces include a 1.5 in extender, noted on the product page.

Not sure? Measure a necklace you already love from end to end, clasp included.

Earring sizes

Hoop sizes are the outside diameter in millimeters. As a guide, 10 to 12 mm hoops hug the lobe, 15 to 20 mm hoops are everyday size, and 25 mm and up make more of a statement.

Ring sizes

Our rings come in US sizes. To find yours, wrap a strip of paper around the base of your finger, mark where it overlaps, and measure the length in millimeters. Or measure the inside diameter of a ring that fits you.

US size Inside circumference Inside diameter
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

Between sizes? Go up a size. Fingers are a little larger at the end of the day and in warm weather.
