Everything you need to know.

Why Does the Fit Change Throughout the Day?

Finger size can change with temperature, exercise, diet, and sleep. Minor changes are normal, so wear the sizing ring at different times of day to ensure a comfortable fit.

How Tight Should GemRing Fit?

GemRing should fit snugly without feeling restrictive. It should not spin or slip off easily, but you should still be able to rotate it slightly and remove it comfortably over your knuckle.

What If I’m Between Two Sizes?

Choose the larger size. Your fingers may swell slightly due to temperature, activity, or time of day. A slightly larger size usually provides greater comfort throughout the day.

Which Finger Should I Wear GemRing On?

We recommend wearing GemRing on your index, middle, or ring finger. Choose the finger where it fits securely, stays in place during daily activities, and feels most comfortable.

Are Ring Sizes the Same on Both Hands?


Not necessarily. Ring size can vary between hands and fingers, so try the sizing ring on each finger instead of choosing based on the opposite hand.
