a few tips from Kelly


Looking to find that perfect ring size? No worries, I've got you covered with some simple yet effective tips:

Use Your Existing Ring as a Guide - If you already have a ring that fits like a glove, go ahead and order the same size. It's an easy way to get it right!

Trust in Standard Sizing - Our rings follow the US standard size closely (within +/- a quarter size). But here's the catch: make sure you've measured your finger properly to ensure a spot-on fit.

Mind the Temperature - Timing is everything! Avoid measuring when you're too cold or too hot. Cold fingers tend to shrink, while warm fingers expand – resulting in not-so-accurate readings. Aim for a room temperature measurement for the best results.

Consider Band Thickness -Thicker bands feel snugger than their thinner counterparts. If your ring has a chunkier band, like, "knuckle to knuckle" chunky, think about going up at least a full size to ensure a comfortable fit.

Knock, Knock, Knuckle Talk -Speaking of knuckles, they can play a role too. Your ring should slide over your knuckle comfortably. If your knuckle is significantly larger than the base of your finger, measure both areas and pick a size that's a happy middle.

Cracking the Gift Dilemma -Gifting a ring? It can be a puzzle, but here's a neat trick. Borrow a ring from the recipient (same finger, of course), pop it on your finger, and mark where it fits. Measure that spot to pinpoint the size you need. It's a bit of work, but totally worth it!

There you have it! Armed with these tips, you'll be well on your way to finding that ideal ring size.

Happy ring hunting!
