Jewellery Size Guide

When it comes to jewellery, sizing is key. We want yours to fit like a dream and drape exactly the way you want it.

Use our quick size guides below to find your perfect match for our rings & necklaces. 


The Ring Size Guide

To find your perfect ring size in our rings, use our easy table below to convert your usual ring size to a Constellations size Small (S), Medium (M), or Large (L), using your equivalent UK or US ring size. Alternatively, simply measure the circumference of the finger you'd like to wear the ring on, and follow the steps below.

  1. Wrap a strip of paper around your finger where you’d like your ring to be.
  2. Make sure that the paper is pulled snug to your finger, the tighter the better, to find your best fit.
  3. Mark the spot where the paper meets and measure the distance with a ruler (in mm).
  4. Use the below chart to determine your ring size.

Having this range of length allows you to create the perfect graduated necklace stack for necklace layering, or wear your necklace solo at the perfect length for your look. You'll find this info in the product details.
