Find your ring size
If after using our chart below you’re still unsure of your ring size, select ‘Not sure’ for your ring size from the drop down menu and we will send you a complimentary ring sizer prior to commencing your ring. Once you receive your ring sizer please send us an email with your order number and correct ring size. Please allow an extra 1-2 weeks production time for this option.
