Before
You Buy A Diamond Ring, Determine Your Ring Size: Wrap a string, or a strip
of paper (no wider than 1/2") around your ring finger. Use a pen to mark
the point on the string/paper where it overlaps, forming a complete circle.
With a ruler, measure the length from the starting end of the string/paper
to the pen mark. Divide the resulting number by 3.14 to get the diameter
of your finger. Use the converter below to determine your ring size, or
to convert your ring size to those used by jewelers in other nations.
