Worth saying plainly, because most of the shop is the opposite: these are not rated for water. Not one of the forty-two carries a water rating, and acetate should not go in a pool, the ocean or the shower.

Treat them the way you would a pair of glasses. Take them off before you swim. Wipe them dry if they get caught in rain. Keep them out of sunscreen and hairspray. Do that and they hold their colour for years, because the colour is in the material rather than plated onto it — there is no finish to wear through.

If you want hoops you can leave in through a shower and a night's sleep, that is huggie hoop earrings instead — steel, rated waterproof, and built for exactly that.

Holly is eighteen of the forty-two, in three sizes. Mini for an everyday hoop that reads as jewelry rather than a statement; Medium; and Mega at 65mm, which is the one people mean when they say big hoops. Ivory Pearl, Champagne Sparkle, Brown Tortoise and True White are the strongest sellers of the line.

Ashley is fifteen, in Medium and Mega. Sunrise, Latte, Autumn Bouquet, Azalea Pink, Citrine — the colourways run warmer and more marbled than Holly's.

Margo Scallop is eight, and the odd one out: a scalloped edge rather than a plain round, which is why those eight also sit in statement earrings. Crimson glitter, silver glitter, pearlized pink and plum, purple stripes.

The acetate never goes through your ear. The post does, and on all forty-two of these it is 316L surgical-grade stainless steel, copper free and nickel free.

That is the distinction that matters if you react to most earrings. A reaction is almost always to nickel in the metal that sits inside the piercing, not to the material of the earring you can see. A large acetate hoop on a steel post is one of the few ways to get scale and colour without putting a base metal into a sensitive ear.

• Material: acetate with a 316L surgical-grade stainless steel post, on all forty-two.
• Water: not rated. None of the forty-two is made for the shower, the pool or the ocean.
• Price: $5 to $40. Twenty-four of the forty-two are $24.

Hoop diameter varies by size and line and is listed on each product page.

All forty-two of these sit inside hoops and huggies, which is where to go if you want to compare them against the steel ones side by side. For the same material at a bigger scale, acetate statement earrings runs to a hundred and thirteen styles; for the smallest version of it, acetate studs.

And the rest of the shop — the pieces built to be left in rather than taken off — is hypoallergenic waterproof jewelry.

A plant-based plastic derived from wood pulp and cotton fibre, and the same material used for quality eyeglass frames. It is moulded and polished rather than cast, which is why it takes marbling, glitter and transparent colour that metal cannot hold, and why it weighs so little at scale.

No. None of the forty-two is rated for water. Acetate is durable in ordinary wear but it is not made for chlorine, saltwater or repeated soaking. Take them off first, and if they get wet, dry them.

Because acetate is far less dense. A 65mm hoop that would genuinely drag on your lobe in brass or steel weighs very little in acetate — so you get the size without the pull, and without the headache by the end of an evening.

Yes, because of the post rather than the front. All forty-two are on 316L surgical-grade stainless steel, copper free and nickel free. The acetate does not touch your piercing at all.

The colour is in the material, not plated onto it, so there is no finish to wear off. What does damage acetate is heat, chemicals and abrasion — so keep them out of a hot car, away from perfume and sunscreen, and wipe them with a soft dry cloth rather than a polishing one.

Mini reads as everyday and disappears under hair. Medium is the middle of the range and the safest gift. Mega at 65mm is a deliberate statement and the one to pair with a plain neckline. Every product page carries its own measurement, which is worth checking — a hoop that looks moderate on screen sits differently against a jaw.
