RING SIZE GUIDE
I KNOW THE FINGER SIZE
If this is the case then please select the correct size from the drop down on the ordering page. The size options are from the ‘British’ system – if you are using another system then please consult the table below to determine the size to select. We may have to charge for resizing a ring. Please contact us if you need some assistance.
I DON’T KNOW THE FINGER SIZE
If this is the case, then please select any option from the finger size drop down but add a message to the order or contact us after and state that you need to discuss the finger size. Once your order has been confirmed we will contact you about how we can ascertain the correct size. This can be done in a number of ways including sending samples and we will be happy to help you with this.

Theia’s intriguing form brings together two strong, circular settings, each holding a brilliant diamond, surrounded by diamond halos. The settings – one positioned just above the other, touch, but only very lightly, making this a totally unique piece, perfect for a modern engagement ring that needs to be noticed.
A celebration of brightness and brilliance, the Theia collection makes the most of the interplay of its halo settings within a mount that nods to the classics.
