1.  Using a flexible measuring tape, string or ribbon* measure the circumference of your wrist just above the bone (toward the elbow). SNUG WITHOUT SLACK - (You must measure your wrist and not another bracelet)

 2.  Make a note of the number at the point where the measuring tape meets the 0.

3.  Compare your measurement to the chart below, and choose the corresponding cuff size.  If your cuff appears to be between two sizes, please choose the size up.

*If you do not have a flexible measuring tape, use a strip of paper, ribbon or string and mark it where it overlaps on your wrist. Then measure the length against a ruler. 

Actual Wrist Measurement Cuff Size
5 1/8 - 5 1/2 inches Small
5 5/8 - 6 inches Medium
6 1/8 - 6 1/2 inches Large



To convert from EU to US sizes, please see below.  To determine your ring size, measure your finger at the end of the day when it is neither hot nor cold.

Measure the finger of the hand on which you intend to wear the ring.  Wrap a strip of paper around the finger, ensuring that you leave enough room to slide the ring over your knuckle.

Mark the spot where the paper strip meets and use a ruler to measure the length in millimeters (mm).  This is the circumference of your finger, which corresponds to the EU ring sizing.

Choose your ring size based on the chart below.  If you are between sizes, opt for the larger size. 

Presently, we offer rings in four standard sizes online.  If you do not see your size listed in the drop down menu please contact us through the Contact Us page and we can make arrangements to special order your specific size.  Contact Us.
