Sizing

Piercing jewelry Measurement

To help you understand product sizing accurately, we use both the metric in millimeters (mm) for gauges above 00g and imperial in gauges (g) and inches (") below 00g and for other measurements

For your convenience, please refer to our conversion chart shown for easy reference.

Piercing jewelry Sizes

Jewelry is measured by thickness, diameter and width.

Piercing rings and round clickers are measured by the internal diameter.

Septum Clickers with straight bars are measured by the pin thickness and the internal height.

Straight and curved barbells are measured by the linear width between ball to ball.

    for USA manufactured pieces measured in inches.

    Note that metric manufactured pieces ( most of the world other the USA) will be on the exact millimeter ex: 5-6-7-8-9 mm etc...

    2.5 mm 3/32"
    3.0 mm 1/8"
    4.0 mm 5/32"
    4.8 mm 3/16"
    5.6 mm 7/32"
    6.4 mm 1/4"
    7.1 mm 9/32

    Internal Threading

    Any internally threaded items use the specification shown below

    Wire/Stem Size Internal Thread
    1.6 mm - 14 Gauge 1.2 mm
    1.2 mm -- 16 Gauge 0.8 mm
    1.0 mm - 18 Gauge 0.8 mm

    Attachments are compatible throughout our entire Valkyrie jewelry collection. Exceptions include if noted, from a different supplier or on "end of stock items"

    Please Note :

    0.8 mm threads are the 16g-18g standard for most European, Canadian and other suppliers from the rest of the world but USA made jewelry suppliers may prefer 0.9 mm or equivalent. USA manufacturers still use the standard system and threading.

    Valkyrie products use the European standard and products will generally state what bases/stem/posts to purchase or use with the piece.

    If you are not sure, please check with your supplier or ask us before ordering. Any USA made threaded piece will require another USA made threaded base/stem/post to be used. Anything else in theory should be compatible with each other since the rest of the world uses metric.
