Flat-back earrings for sensitive ears

Two numbers do all the work here. F136 is the ASTM specification for the Ti-6Al-4V ELI alloy used in surgical implants, and G23 is the grade designation for that same alloy. A seller putting both in the title is pointing at a published document rather than reaching for an adjective, and that is rarer than it should be.

The flat back matters as much as the metal. A flat disc sits against the back of the lobe instead of a butterfly clip pressing a small area, which is why piercers use this shape for anything that has to be slept in. Combined with a screw thread rather than a friction push-fit, it is about as low-drama as an earring gets.

What the title does not do is name the back separately. In practice a screw-back on a titanium post is almost always the same titanium, and the design leaves little room for it to be anything else — but the seller has not committed to it in the headline, and we score what is stated rather than what is likely.

This is the plating arrangement to look for. The gold appears in the title attached to the decorative end — 'Gold/White Gold Plated' — while the structural claim, G23 and F136, attaches to the post. A plated front over a titanium post is a completely different proposition from a plated post, because the plating is nowhere near your piercing.

Most listings do not draw that distinction, which is why plated jewelry has a bad reputation it only half deserves. Plating is not the problem; plating on the wrong component is.

Twenty gauge is the standard for a healed lobe or a cartilage piercing done at that size. If your piercing was done at 18 gauge, a 20-gauge post will fit but will move around in the channel more than you want.

The short title is the whole review. It says titanium, screw back, flat back, dot. There is no grade number, no standard, and no adjective doing work it cannot support — which is refreshing, and also less information than the Limerencia listings give you.

A screw-back flat disc is the most secure common fastening. It cannot be pulled off by a jumper, it does not press a point into the back of the lobe, and it is the shape you want if the earring is going to stay in permanently.

The trade-off is fiddliness. Screw threads on small jewelry are awkward with cold hands and easy to cross-thread, and a cross-threaded post is scrap.

'14k gold plated over surgical stainless steel' is a complete sentence about materials, and it is remarkable how few plated listings manage one. You know what is on top and what is underneath.

What it does not give you is plating thickness. Fourteen karat describes the gold's purity, not how much of it there is — a flash plating and a heavy plating can both be 14k. Micron figures, or the words vermeil or gold-filled, are what indicate quantity.

The screw-back and flat-back combination is well suited to cartilage, where security matters more than speed of changing.

This one is genuinely useful and genuinely ambiguous, and it is worth reading the title twice. It says 'Titanium' and it also says 'Surgical Stainless Steel'. Both metals appear in the same set, and the title does not tell you which component is which — so treat it as containing steel unless the seller says otherwise.

That is a real limitation and the reason it does not score higher. For most people steel is fine, so a mixed set is a sensible way to own six sizes cheaply. For someone who reacts to steel, the ambiguity makes this the wrong purchase.

Threadless is the fastening piercers prefer: a post with a pin that friction-fits into the decorative end, so nothing screws and nothing has a sharp thread to drag through a healing channel. It is easier to insert than a screw-back once you have the knack, and harder before you do.

This pick is included as the clearest example on the site of the problem this site is about. The title is six words of benefit language — hypoallergenic, flat back, sensitive ears — and contains no metal whatsoever.

The flat-back shape is genuinely the right shape for a sensitive or sleeping-in piercing. That is a design point in its favor and it is separate from the material question, which the headline simply does not address.

Scored accordingly: the lowest post and back disclosure of anything on this page. If you buy it, read the full listing first, because the title will not tell you what is going through your ear.
