Jewelry sized by millimetres and placement

Our catalogue is organized by where each piece sits on the body. We stamp the exact gauge and post length or hoop diameter in millimetres on every page so you know the dimensions before ordering.

Full gauge table

    Gauge and length decide the fit

    Wire gauge tells you the thickness of the metal post. A higher gauge number means a thinner wire: 20G is 0.8mm, 18G is 1.0mm, 16G is 1.2mm, and 14G is 1.6mm. Your jewelry gauge should match what your piercer put in your channel to prevent stretching or loose posts. A piercer can check your size if you are unsure.

    Length is the second measurement. A 16G post at 6mm sits close to the skin, while the same 16G post at 10mm leaves extra room along the shaft. We machine our core barbells and clickers from 316L surgical steel, a hypoallergenic alloy ground to tight tolerances, then polish the shafts smooth before adding stones or plating.

    Gauge to millimetres, as we cut it. The bigger the gauge number, the thinner the wire.

    From the bench

    Four things we get asked about the metal itself.

    Hinged clicker rings

    Our clicker hoops for nose and septum piercings use a machined pin hinge and an audible snap clasp. We make them in 16G, 18G, and 20G wire thickness with inner diameters measured in exact millimetres.

    Flat back labret studs

    These 16G studs feature a flat circular disc base that rests flush against the skin inside the lip or ear. The front gem unscrews from the internally threaded post so the back stays steady.

    Double flared plugs

    We turn our stone and acrylic plugs with smooth flares that measure roughly one millimetre wider than the wearable center saddle. We list both the saddle width and overall plug length in millimetres.

    Cubic zirconia prong settings

    Our navel curves and cartilage studs hold faceted cubic zirconia gems inside solid steel prongs rather than glue. The metal wraps around the girdle of each stone to keep it secure through daily wear.

    Questions we get about sizing

    What does wire gauge mean

    Gauge measures the cross-sectional thickness of the post or hoop wire. A larger number indicates a thinner wire. For example, 20G measures 0.8mm across, while a 14G barbell shaft measures 1.6mm across.

    How do I find my size

    Check with a professional piercer or measure an existing piece that fits well using a digital caliper. Measure the straight post between the balls, or measure the inside diameter of a hoop across its widest open gap.

    How are lengths displayed here

    All lengths and hoop diameters appear in millimetres. Straight posts are measured along the wearable shaft between the end balls. Rings and clickers are measured across the inner clearance, excluding the thickness of the metal wire.

    How does this catalogue work

    This site displays our full manufacturing line organized by placement and dimensions. We do not process orders or payments directly on this site. Instead, our listings route through an external storefront where inventory is managed.

    Why is a specific size missing

    We machine specific pieces for standard anatomy. If a combination of 14G thickness and a short 5mm length is unavailable, it is because that specific combination is outside standard placement dimensions for that design.
