Helpful Hints :
If your measurement falls between two sizes, choose the larger size ring.
Variations in temperature can affect the size. Cold causes the finger to shrink, while heat makes the finger expand.
For greater accuracy, it's best to measure at the end of the day - that's when your finger is the largest.
Gift Buying Tips :
If you're going to surprise someone with a beautiful diamond ring, try to find out her size so that she can show it off right away.
Here are some suggestions for finding out her ring size:
Ask one of her friends for help.
Take one of her rings and follow the instructions to measure with a string.
Put her ring over your finger to see where it fits. Mark it with a pen and then measure with a string.
Guess-but go with the larger size.
