Assess a body-jewelry supplier through documentation, construction, surface quality, fit and follow-up. A metal color, a high price or a front-facing photograph is not enough to evaluate a complete piercing-jewelry system.
Separate the design from the evidence
A sourcing file should identify the exact decorative top, post and connection system. Ask what is made from each material and which dimensions apply to each component. Keep the supplier’s answer with the SKU or variant, rather than assuming one statement describes the entire collection.
A practical supplier checklist
| Review | Request or inspect | Record against the exact item |
|---|---|---|
| Material | The alloy designation and relevant supporting documentation. | Which component the document describes. |
| Surface | Clear views of the post, end, edges and setting. | Inspection findings and any defects. |
| Connection | Threadless or internally threaded construction and compatibility. | The matching post and approved assembly. |
| Dimensions | Gauge, wearable length and decorative-top measurements. | The ordered size and permitted alternatives. |
| Processing | Manufacturer instructions relevant to cleaning and sterilization. | Instructions for the actual stone and assembly. |
| Service | Replacement parts, defect reporting and lead times. | Supplier contact and the agreed resolution process. |
This is an administrative purchasing checklist. It does not replace professional training, studio infection-control procedures or the requirements that apply to your work.
Use precise material descriptions
The Association of Professional Piercers distinguishes suitable initial-jewelry materials and describes the importance of documentation, finish and dimensions. Examples in its guidance include specified titanium grades and appropriately alloyed gold of 14K or higher. It also distinguishes internally threaded and threadless closures from external threading. Read the APP initial-jewelry guidance for the complete context.
Inspect the complete assembly
Request views of the back as well as the decorative front. Look at how the top meets the post, how a setting projects, and whether the stated measurements are clear. Check compatibility with the supplier instead of relying on a general claim that parts are universal. Set aside a damaged or uncertain item for supplier review; do not solve an undocumented component mismatch at the client’s appointment.
Keep catalog examples separate from initial-wear approval
The current Nina Wynn flat-back listings shown below describe solid 14K gold decorative tops with an included 5 mm titanium post, with gold posts sold separately. That supplied length does not establish a correct starter fit. A professional must assess the actual components, documentation, processing requirements and individual placement before deciding whether an assembly is suitable. No product on this page is represented as APP certified or universally suitable for fresh piercings.
Build a repeatable order record
Record the supplier, SKU, variant, materials, dimensions, matching components, document location and inspection outcome. When ordering again, check whether any of those details have changed. Keep client fitting decisions separate from the purchasing record so a stocked size does not become an automatic choice for every person.
Questions and answers
Does a 14K stamp establish everything I need to know?
No. It does not by itself identify every component, the full alloy, surface quality, setting or correct dimensions for a particular placement.
Are threadless components universally interchangeable?
Do not assume that they are. Confirm the exact top and post compatibility with the supplier.
Does this checklist approve a product for a fresh piercing?
No. It organizes supplier questions. Product and placement suitability still require professional assessment and appropriate documentation.
