Ring Size Guide
Let’s make sure your Crytale ring fits you perfectly, as if it were made just for you.
Measure an Existing Ring
If you already have a ring that fits well, this is the easiest way.
1. Pick a ring that fits comfortably on the finger you have in mind.
2. Measure the inner diameter straight across from one inside edge to the other.
3. Compare your measurement to our size chart to discover your ideal size.

Measure Your Finger
No ring at home? That’s completely okay.
1. Take a thin piece of paper and wrap it snugly around the base of your finger.
2 Mark the point where the paper meets itself with a small dot.
3. Lay the paper flat and measure the length in millimeters.
4. Match that number to our size chart for your perfect fit.
