Ring size guide
Typically rings should be made to a standard size, however you will find that many ring size guides differ.
Our rings are made to the standard USA sizes, we then provide a guide as to the nearest UK size (There is not always an exact match).
We recommend using a ring sizer mandrel with both UK & USA sizes.
Below you will find a ring size guide which also shows the inside diameter of of our rings which should be used for a more accurate measurement.

Description
Comfort fit Stainless Steel Band Ring Cores 8mm width
The thickness of this core is 1.5mm - this is thinner than our other stainless steel ring cores which are 1.75mm and gives greater freedom for the blank to be thicker and therefore more stable and less likely to crack.
Comes in 2 sizes: 6mm & 8mm
Available in sizes L1/2 to Z+7 (USA 6 to 16)
