Ring Size Guide: How to find your perfect ring size.

Method 1

• Select a ring which you own that properly fits the intended finger. 
• Measure the inside diameter of the ring in millimeters. 
• If the ring falls between two sizes then we suggest buying the larger size.

Method 2 

• With a piece of string measure around the intended thumb or finger again ideally in millimeters 
• Match this with the circumference in the table below. 
• We recommend selecting the larger size if it falls between two sizes.
