Finding Her Ring Size
Ordering a correct ring size is made easier with these suggestions:
If the ring recipient’s finger is not available for measuring (surprise gift), use a ring from his or her present jewelry collection to help find the correct size. Use the chart below as a guide.
Asking the ring recipient’s close friend or relative for a ring size is another option to finding out a correct ring size.
If the ring is not a surprise, we will be happy to send you a free, plastic ring sizer in the mail. Call us at 212-480-5125 or send us an email at service@sarkisiansjewelry.com. You can also contact us to request a plastic ring sizer.
Helpful Hints
- Dominant hands are generally slightly larger.
- Rings that are wider will fit tighter. Try to measure a ring of a similar width as the one you want to purchase.
- When in between sizes, larger is better. You’ll want the ring to slip on her finger easily when proposing.
- Warm, humid weather makes fingers expand. Allow room for weather changes.
