The most accurate way to determine someone's ring size is to have the size determined by a local jeweler. But we undertand that this may not be possible if the ring is meant to be a surprise.

We are not able to get our rings in half sizes. If you need a half size, we recommend getting the next smaller size and taking the ring to a local jeweler to have it expanded professionally. Most of our rings can be safely expanded up to one full size with no damage to the ring. One exception to this would be any of the spin rings. Very wide styles, such as RSS-057, sometimes fit better if they are slightly larger than one's normal ring size (about 1/2 size larger is a good rule).

There is no difference between "men's" and "women's" sizes in rings. Typically, women will fall on the smaller end of the spectrum (6,7,and 8 are common women's sizes), while men typically require larger rings (sizes 9 and up are the most common).

Remember that whatever size you decide on must be able to fit over the knuckle while still fitting snugly and comfortably below it.

If you know your ring size as a letter rather than a number, see the chart below to translate that to a number.

If you don't know your ring size, but already wear a ring, take the ring off and trace around the inside, then measure the diameter and compare to the chart below. The actual size of the rings varies slightly. Typically they run no smaller than listed, but can run up to approximately 1/2 size larger - this varies by design, so all of the size 10's of a given ring should be very close in size.

If by chance you order a ring and find that you need another size, we will gladly exchange it for you.
