  • Product # 28717
  • Material(s): PVD plated steel, Synthetic gemstones, Rhodium plated

Internally threaded jewelry is where the shaft has threads inside the metal. So basically the ball has threads sticking out of it that screw down into the metal shaft.

The below measurements are approximate:

  • All sizes have a 5/16" wearable area
  • The overall length measures 13.5-14mm
  • The back is internally threaded
  • The alien front design is made with anodized rhodium plated steel with black CZ gem accents
In our drop-down menus for adding to cart, we show the gauge of the item you are ordering, then the length/diameter, then the ball size if it has any:

Jewelry is measured through a gauge system (see chart below). The higher the gauge number the smaller the wire is. A standard "earring" is usually 20 gauge. Jewelry gauges/sizes can vary between manufacturers. There is no universal regulation on companies to make a standard size in body jewelry. A big part of this is that some jewelry is made overseas and measured in millimeters. And in the USA jewelry is measured in inches/gauges. So many times jewelry can be anywhere from .5mm to 1mm different.
