Sizing Tips

When choosing a ring size:

Choose the ring size of the largest finger you’ll be wearing the ring on. When measuring, round to the nearest whole millimetre.

Stackable rings:

For a looser fit, select one size up from your normal ring size.

Wide shank ring:

This ring has a wider band. We recommend one size larger than your normal ring size.
