Ring Sizing Tips

For the most accurate fit, measure your finger at the end of the day when it’s at its largest. Cold weather can cause your fingers to shrink by up to half a size, so be sure they’re warm before measuring. Additionally, alcohol and salty foods can lead to temporary swelling, so it's best to avoid measuring after indulging in cocktails or appetizers.
