Our rings can be resized to ensure they fit comfortably and safely. For our online customers, should you know the size you require, please include this information in your purchase details.

If you would like the ring that you purchase online to be resized, but are unsure of the size required, then refer to the ‘Ring Size Comparison Table’, below (Ring resize will incur a small charge). In Australia, the lettered British standard is used and the table below will provide a conversion for our international customers.

Additionally, if the purchase is a special gift, you can make an impression of an existing ring which fits the desired finger and measure that against the table below. .
