Measure in the eveningFingers naturally swell slightly throughout the day — evening gives the most accurate size.
Avoid cold handsCold fingers are smaller than usual. Measure when your hands are warm for the best result.
Wider bands fit tighterIf your ring has a wider band, consider going half a size up for a comfortable fit.
Between sizes? Go largerIf you fall between two sizes, always choose the larger one — it's easier to adjust a ring down than up.
Should your ring need a small adjustment when it arrives, we offer one complimentary resize within 30 days — just get in touch and we'll take care of it.
