Prysm jewelry necklace length

For the average build, here are the most standard lengths: 

  • 14”/36 cm - choker style
  • 16”/41 cm - sits right below the collarbone, an everyday short piece
  • 18”/46 cm - sits more in the middle of your chest, an everyday piece *most popular length & the best option if buying as a gift
  • 20”/50 cm - between collarbone and bust, falls a few inches below collarbone
  • 30”/76 cm - a longer necklace, can slip over your head.

- Please note, this is just a guide. If you’re petite or have a larger neck, consider sizing down or up for your perfect length. 

- Don't forget to consider that the pendant will make the necklace seem longer when determining your length.
