We want to ensure that the ring you purchase will fit perfectly, the first time! It may appear that finding your ring size is easy given all the online tools and sizing charts available on the internet, however, choosing the correct ring size for a particular ring design can be a little tricky. We have included some guidance material below for the purpose of giving you some idea of your ring size as a starting point.

We want you to avoid the inconvenience and cost that comes with resizing, so please have the finger you intend to wear the ring on sized professionally. Most local jewellery stores will be more than happy to do this for free. 

Tips for your professional fitting:

Your finger size is dependent on the time of day and weather. For best results, try on your ring at the latter parts of the day and when your finger is warm.

A ring that fits you perfectly shouldn’t slide off too easily or feel too tight. In between is just right. It shouldn’t be able to be shaken off, nor should it feel uncomfortably tight around the finger.

You need to factor in the width of the ring when choosing your ring size. We recommend you try on a ring that has a similar width to the one your looking to buy. That way you can be confident that the ring you order will fit perfectly.



Request a complimentary plastic ring sizer. It comes with easy to follow instructions so that you can measure your ring size in the comfort of your own home.
