These delicate little hand made stacking rings are made from sterling silver round wire and the cup is 9ct gold.
Dimensions:
The wire is 1.5mm thick and the diameter of the gold cup measures approximately 4.5mm. The thickness of the gold is approx 0.50mm
I make each ring by hand and therefore there may be tiny variations in size from the dimensions stated.
 
The rings are hallmarked.  All hallmarks including my maker's mark are applied by the Edinburgh Assay Office.
