Ring Size Guide

Don't know your ring size? Download our printable ring sizer that can help you determine your ring size. Important! Prior to printing, ensure that page scaling is set to "100" on your print dialog box.

Tips: If you want to wear stackable rings (multiple rings on one finger) or wide band rings, please consider that the ring should be half or one size bigger than your regular size since multiple rings or wide band rings usually fit tighter than a thin band.

Choosing Your Sparkle—Subtle Shimmer or Bold Radiance?

Does size matter? Absolutely. Compare our bezel-set eternity bands to decide between a subtle shimmer or a radiant shine.

  • 1.5mm Stone | The Glimmer:Dainty & Subtle. A sophisticated whisper of light. Ideal for minimalists or for adding a hint of sparkle to an existing stack without adding bulk.
  • 3mm Stone | The Glow:Bold & Radiant. A confident statement piece. With stones double the size, this band offers serious brilliance and looks stunning worn all on its own.

Quick Tip:
Choose The Glimmer to complement your engagement ring, or The Glow to replace it as a standalone travel band.
