The four checks, in order
1. A standard number, not an adjective. "ASTM F136" or "ISO 5832-3" is checkable. "Implant grade", "surgical grade" and "hypoallergenic" are not — none has a legal definition for jewellery, and anyone can print them.
2. Threading type stated. Externally threaded jewellery drags a screw thread through your piercing channel on the way in. Internally threaded or threadless presents a smooth bar. Good sellers state this; cheap listings usually do not, because their stock is externally threaded.
3. Gauge and length given separately. A listing that says only "16G" without a post length or a hoop diameter is missing the measurement that most often makes a piece unwearable.
4. A real returns policy. Check whether you get money back or store credit. Many large body jewellery retailers issue store credit only, with no cash refunds at all — which means an item that does not fit becomes a voucher, not a refund.
Warning signs on a listing
- "Surgical steel" with no grade. 316L and ASTM F138 are specific. "Surgical steel" alone could be several alloys, all containing nickel.
- A price that cannot support the material. Certified titanium, machined and internally threaded, has a floor cost. A £2 piece described as implant-grade titanium is describing something else.
- No gauge or length anywhere. Serious sellers list both because they know it is the main cause of returns.
- Stock photos with mismatched pieces. A listing whose photos show different threading or finishes across images is not photographing its own stock.
- Reviews that never mention fit. Genuine body jewellery reviews mention sizing constantly, because that is what buyers care about.
| Check | Good answer | Warning sign |

| Price | Consistent with the material | £2 "implant grade titanium" |
What to check before ordering
What UK consumer law actually gives you
Two things are worth knowing, and both are frequently misunderstood.
Nickel release is legally capped. Under REACH Annex XVII entry 27, jewellery inserted into a pierced part of the body must release less than 0.2 µg/cm² per week, tested to EN 1811. This applies to anything sold into the UK regardless of where it ships from.
Distance selling rights have an exception. Under the Consumer Contracts Regulations you normally have 14 days to change your mind on an online order. However, sealed goods that are not suitable for return for health or hygiene reasons are exempt once unsealed — which covers body jewellery that has been opened or worn. Unopened items are generally still returnable.
Separately, goods must be as described and of satisfactory quality under the Consumer Rights Act 2015. Jewellery sold as ASTM F136 titanium that turns out not to be is a straightforward misdescription, regardless of the returns policy.
The questions worth asking before ordering
Which standard is your titanium certified to, and can you provide the mill certificate?
Is this piece internally threaded, externally threaded, or threadless?
What is the post length or inner diameter, and what gauge?
If it does not fit, do you refund to the original payment method or issue store credit?
Four short questions. A supplier who answers all four clearly is one worth buying from; a supplier who deflects on any of them has told you something useful.

Sizes and healing times on this page are typical ranges, not guarantees — anatomy varies and healing differs from person to person. Your piercer has seen your piercing and we have not: check with them before changing jewellery, especially on one that is still settling.
