How to choose a ring size?

It is important that you choose the right ring size. All silver coin rings, can be resized (with silver content 0.800 or above). However, if a ring is plated with silver, it’s not possible to have the piece resized as the resizing process will ruin the plating.

Why silver plating?

When using non-silver (clad) coins to make into coin rings, sometimes your finger can turn a greenish-color. This is primarily due to the nickel and copper metals reacting to your skin. Silver plated coin rings prevent this and they also look much better.

How to measure your ring size properly

Option 1:

Visit a jewelry shop and ask them to measure your finger.

Option 2:

If you have a ring at home that you know is the right size, take a caliper and measure the inside diameter of the ring.

Option 3:

You will need following props: piece of string, scissors, pen and ruler.
– Wrap the piece of string around the base of your finger.,
– Mark the string at the exact point that it overlaps to make a compete circle around your finger,
– Unroll the stringand place it against a ruler that is divided in millimeters. The lenght between the two marks on your string the ruler is the circumference of your ring finger (C). Refer to a ring chart to get your ring size (D).
