Due to the exclusive multi-layer Rhodium, Palladium and Platinum plating Diamonfire jewellery and rings cannot be re-sized. Rings are available in the following sizes (nearest UK size in brackets):
16 (K), 16.5 (L1/2), 17 (M1/2), 17.5 (O), 18 (P), 18.5 (Q1/2) & 19 (R1/2).
To find your UK ring size, please follow this guide in mm:
Take a piece of string or a piece of paper.
Wrap it around the base of the finger.
Use a pen to mark the point on the string or paper where it overlaps. The overlap should form a complete circle.
Now use a ruler to measure the length of the string or paper from the starting end, to the end you marked with the pen.
Finally, use this measurement and compare it against the chart below to determine your ring size.
