Piercing Jewellery Materials & Finish
Piercing Jewellery Materials & Finish
Material quality matters, but the name of a metal on its own is not enough. For body jewellery—especially initial jewellery—the specification, alloy, surface finish and construction all need to be considered together.
Specification matters more than a vague material label
Implant-certified titanium
The APP identifies implant-certified Ti6Al4V ELI titanium meeting ASTM F136, titanium meeting ASTM F1295 or ISO 5832-3, and commercially pure titanium meeting ASTM F67 among suitable titanium specifications for fresh piercings.
Steel
“Surgical steel” is not a guarantee of suitability. The APP specifies particular compliant grades, including ASTM F138 or ISO 5832-1, rather than treating all steel jewellery as equivalent.
Niobium
Niobium has a long history of use in professional piercing. The APP notes that it does not have an implant-grade designation, even though it has been widely used successfully.
Solid gold
For initial piercings, APP guidance describes 14k–18k gold as potentially appropriate when it is nickel- and cadmium-free and alloyed for biocompatibility. Higher karat is not automatically better: gold above 18k can be too soft for body jewellery.

Why the construction of the material matters
Solid gold jewellery is made from a gold alloy throughout the wearable piece. Gold-plated, gold-filled, overlay and vermeil jewellery use a gold layer over another material and are not equivalent to solid gold.
The APP does not consider those coated gold products appropriate for fresh piercings because the surface layer can wear or chip. That distinction is important even if two pieces initially look similar.
Smooth, polished and well constructed
For fresh piercings, APP guidance calls for wearable surfaces and ends free from nicks, scratches, burrs and polishing compounds, with metal jewellery polished to a smooth mirror finish.
Gemstone settings also matter. Stones should be securely set in well-made settings, and the jewellery should fit together accurately without gaps or rough transitions.
A suitable alloy with a poor finish or damaged surface is not the same thing as a properly manufactured, well-polished piece.
More options become possible after healing
Initial jewellery has stricter material and construction requirements. Once a piercing is fully healed, the APP notes that a broader range of materials and finishes may be tolerated, but quality, weight, surface condition and individual comfort still matter.
