If you intend to purchase a ring with a trim or a wide fitting ring we suggest you go up a 1/2 size than your normal ring size for e.g. if you are normally a size 6 you would then need to order a size 6 1/2. Please note that we manufacturer all our rings based on a centre sizing measurement unless specifically specified otherwise as "Leading Edge Measurement Given".

If you require a ring size above or below what is displayed on our website please email us with the size you require and we will arrange for it to be made.
