TIPS
Measure the exact ring size in the right conditions:
At noon - Midday is the most frequent temperature and moisture of your region. *Fingers will swell more in the evening than in the morning. They will also be thicker in summer than in winter. Heat makes fingers thicker. Cold makes fingers thinner.

*Be sure! The difference in diameter between one size and another is less than 0,32 mm.!
The wrong measurement can cause easily the loss of your precious ring or, when the ring is to small, it hurt or you cannot put the ring on your finger!
