Ring Sizing

RING SIZE

Please note we use the US/Canadian ring sizing system and that half-sizes are currently unavailable. If you require a half-size ring, we recommend selecting the next full size up as each order will come with a complimentary half-sizer that will fit discreetly onto the band and fill up the excess space. Please see the image below.

To determine your US/Canadian ring size:

• Use a piece of string or similar and wrap it around the base of your finger.
• Use a pen to mark the point on the string where the end meets the string.
• Use a millimeter ruler to measure the string from the end to your mark.
• Choose the closest measurement in the Left-most column of the chart and then find your US/Canadian ring size in the column to the right of that.

Alternatively, if you know your ring size using another system:

• Please find your ring size in the appropriate column and then move to the left until the "US & Canada" column to find your corresponding ring size.

Tips for best results:

• Allow enough room to accommodate your knuckle.
• Measure the finger on the hand on which you plan to wear the ring. Finger measurements can differ between hands.
