The jewelry industry uses the metric system of measurement that can be confusing to many of us. All our jewelry states the mm (millimeter) size in the description. Use this chart as an aid to visualize sizes of our jewelry.

Metric (mm) to Fractions.

The left size lists the metric chart and the right size lists English units in fractional inches.
The phantom shadow in the back ground is a U.S. nickel that is approx 21mm high.
A U.S. dime is approximately 18 mm high and a penny 19 mm high.
See Chart below for more comparisons to fractions.
