Size Guide
Find your fit for any piece. Measure carefully, a quick check saves a return.
Rings
Find your ring size in 10 seconds.
- Cut a thin strip from any piece of paper (a notepad or an envelope), or use a piece of string, and wrap it snug around the base of the finger you want the ring for.
- Mark the spot where it overlaps.
- Lay the strip flat on a ruler and measure up to the mark, then find that length in the chart below. Measure twice to be sure.
Necklaces
Not sure on length? Here is where each sits.
- The shorter length rests right at the collarbone.
- The longer length sits just below it on the chest, the better drop for a pendant.
- Layering two? Step the lengths apart so each one shows.
Bracelets
Measure your wrist in 10 seconds.
- Cut a thin strip from any piece of paper (a notepad or an envelope), or use a piece of string, and wrap it around your wrist, just below the wrist bone.
- Mark where it overlaps, then lay it flat on a ruler.
- Add a little room for comfort, then match the length to the chart below.
