If unknown the simplest way to find out her ring size without raising suspicion is to ask her best friend or a family member such as her mother or sister. If you are unable to get this information The Diamond Shop can make it easy for you with a Multisizer ring sizing gauge or by using our handy Ring Size Chart.

THE DIAMOND SHOP RING GAUGE

The Multisizer works like a belt. Simply push the end through the buckle to form a ring shape. Slip the multisizer onto your finger. Adjust to give a comfortable fit, checking that it just slips back over the knuckle. When the best fit is found simply read off the size indicated by the arrow (size 7 shown). The Multisizer will cost you five dollars by adding it to your cart. To order please click here.
