Your ring should fit over your finger comfortably, snug enough so that it will not fall out, but loose enough to slide over your knuckle.

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 to minimize errors.

Avoid using string or paper to measure ring size as these materials can stretch or twist, yielding an inaccurate measurement.

Tips for buying the ring as a SURPRISE

Ask her friends or mother if they know her finger size.
Borrow one of her rings and use the ring measurements in our RING SIZER to determine its size.
