HOW TO FIND THEIR RING SIZE
How To Measure UK Ring Size In Secret
Are you wondering how to measure your partners’ ring size in secret? These helpful tips below will be your go-to guide. Here are 5 possible ways of finding their ring size so you can make it the most unforgettable surprise of their life…
1
Try-On For Size
Take one of their rings and slide it onto your ring finger. Make a mark with a pen where the ring goes to on your finger and speak to one of our friendly experts on our live chat or via our WhatsApp
2
Get Creative
Why not get creative and buy some Play-Doh. Gently press one of your loved one’s rings into it and book an appointment in our London offices or send it via royal mail special delivery so one of our experts can check the ring size. Remember to clean the ring afterward, and be careful not to get any playdough on the setting or diamond.

Tying The Knot
Wait until they’re fast asleep and tie a piece of string around their finger and make a little knot. Just try your best not to wake them and you’re all set.

Tell a Fib

Something Borrowed
If you know your loved one won’t miss a ring that they wear then simply book an appointment in our London office so one of our experts can measure the ring size. Just remember to put the ring back before they notice.
