What Quality Control Looks Like in Body Jewellery
The short answer
In professional jewellery manufacturing, quality control means every finished piece is individually inspected: dimensions verified against specification, surfaces examined for finish and flaws, threads tested where present, and the batch’s material documentation kept intact. Anything imperfect never reaches a studio.
Real quality control inspects every single piece — dimensions, surface, threads and documentation — and rejects anything imperfect before it can ever touch skin.
One piece at a time
Mass production relies on spot checks; professional body jewellery is made in smaller numbers and inspected individually. A finished earring is measured against its specification, examined under good light for surface flaws, fitted together to confirm its parts seat cleanly, and — critically — traced back to its material documentation. Only then does it earn its packaging.
What the bench is checking
- Dimensions. Post length, gauge and setting size must match the specification exactly — see why post length matters.
- Surface. No scratches, no tool marks, no pits — the finish skin will actually touch.
- Fit. Backings seat cleanly; nothing catches or wobbles.
- Paperwork. The batch’s material certificates stay attached to the batch — see implant-grade certification.
Why studios care so much
A studio that buys documented, inspected jewellery is choosing what sits inside a child’s healing skin for months — quality control is the manufacturer’s half of that promise, and careful sourcing is the studio’s half. See polish and inspection, or return to the jewellery guide.
