MANUAL MEASUREMENT
1. Cut a strip of paper
2. Wrap it around your finger, snug
3. Mark where the paper overlaps
4. Lay it flat and measure on millimeter side of a ruler – that measurement is your finger’s circumference.
5. Find your measurement in the ring size guide and that’s your ring size!
FAQs - TIPS FOR MEASURING RING SIZE
MEASURING YOUR FINGER
Your ring should fit your finger comfortably; snug enough so that it will not fall off, but loose enough to slide over your knuckle with some resistance.
Finger size changes depending on the time of day and the weather. For best results measure your finger size:
1. At the end of the day and when your fingers are warm (fingers are smaller in the early morning and when cold.)
2. Measure finger size 3 to 4 times for accuracy.
Temperature is important
Don’t measure when your body temperature is either too cold or too hot. A cold finger shrinks while a hot finger expands causing an inaccurate reading.Exercise, salt, alcohol, hormones, etc. all make your fingers swell. Lack of sleep and flying on planes generally makes hands swell.
When two sizes seem to fit
If you are between two sizes, go with the larger one.
Don’t use strings
Strings tend to stretch, which can result in a wrong size.
Big knuckles can affect your size
If your knuckle is larger than the base of your finger, you may need to go up a half size.
A wider band needs a bigger size
If you are purchasing a wide band, you will be more comfortable moving up a half size from your measurement.

TIPS FOR BUYING A RING AS A SURPRISE
Borrow one of the recipient’s rings (from the correct finger) and use the ring measurements on the first page to determine its size. Please make sure beforehand that the ring you are purchasing can be resized. Rings with stones or patterns all the way around usually cannot be resized. Most other rings can be resized for a nominal fee. For best results, measure a plain, narrow band. Extra wide band styles tend to fit slightly small. If your borrowed ring has a narrower shaft than the one you wish to purchase, you may wish to order a ring a size larger than the normal size worn. Also, large stone rings may cause the shank to lift up when laid on its side on the display, slightly distorting the size measurements.
RESIZING RINGS
Some rings can be resized, others can’t! It seems quixotic but it’s not; if a ring has a full pattern or stones all, or most, of the way around, it generally cannot be resized. Our customer service team is always happy to help with specifics!
Choosing Band Width
If you are purchasing a wide band, you may be more comfortable moving up a half size from your measurement. Wider bands will fit tighter than thinner bands of the same ring size. For example, a size 9 band that is 5mm in width will have a tighter fit than a size 9 band that is 1mm in width.
Choosing the best band width for you is also a very personal choice! For help with determining which band width might look best on your hand, download our Ring Sizing Guide, which includes a Width Guide that you can print out and try on!
NECKLACE SIZING
We make necklaces as short as 12.5” and as long as 26”. Most necklaces can be worn at varying lengths, for an optimal fit. Chokers range from 12.5” – 15”, necklaces up to 15.5” inches generally sit right along the collarbone, and 16” and longer are more traditional necklace lengths.
