Ring Size Guide
Ruby & Sky uses standard ISO ring sizing and use the US and Canadian system of a numerical scale 4 -11.
Australian ring sizes are specified using an alphabetical scale so if you know your Australian size please refer to the chart below to determine your US size.
This chart also helps in converting different international sizes as well as determining ring size by measuring the inside diameter and circumference of an existing ring.
