ALLEGRA RUBY PEAR AND DIAMOND STYLE RING ADJUSTABLE

Top Tip: To measure your finger at home, use a piece of string to measure the circumference of your finger in millimetres.

You can get the closest size, so if your finger is 49MM you can go for an EU50.

You can also get the size from an existing ring that you know fits by downloading the 'Ring Sizer' app which allows you to quickly measure your ring on screen!
