Size Charts


For clarity, we have divided our sizing conventions into charts as follows:
Gauge
Gauge is a measure of the thickness of the wire element of a piece of jewelry. In body jewelry it refers to the point at which the jewelry will rest in the piercing site.
Ball size
The size of the ball in each jewelry item.
Length
The shortest distance between 2 ends of the piece – not including any attachment like balls.
Rings size
The inside diameter of the ring in each jewelry item.
