Ring Size Tester
Not sure what your ring size is?
Use our free ring sizer tool!
- Measure your finger at midday in room temperature.
- Use our Ring Sizer tool like a belt and tighten it around the base of your finger until it is snug (but not tight).
- When you go to take it off, it should move over your knuckle with slight resistance.
The goal is for your ring to be a comfortable middle ground between falling off and being too tight.
Superior Quality & Craftsmanship
Each piece is carefully crafted to last a lifetime by jewelers with over 15 years experience.
