Materials and care
What they're made of
Almost all Trevani pieces are in 316L stainless steel with a PVD finish. The exception is Duna, in 925 silver: it has a section of its own, below.
316L steel is what's commonly called surgical steel: the same alloy used for medical instruments. It doesn't rust, it doesn't oxidise, and its nickel release on contact with skin is minimal.
PVD (Physical Vapour Deposition) is a coating applied in a vacuum at high temperature. It isn't an electroplated gilding that wears away with rubbing: it is bonded to the metal underneath. That's the reason the colour stays where it is.
One clarification we care about: it isn't gold. It's steel with a gold-tone finish, and that's how we describe it everywhere.
How to wear it
Every day, even to sleep.
Like any piece you love, it comes off before the shower, the sea and the pool. And it's the last thing you do before going out: put it on after perfume and cream.
What to avoid
Perfume, hairspray, sunscreen, harsh products in direct contact.
They don't ruin the piece, but over time they dull it: the finish loses its shine. The practical rule is simple — the jewellery goes on last, after perfume and cream.
Also avoid bleach and household cleaning products: those really do cause damage.
How to clean it
Lukewarm water and a soft cloth. Pat dry.
On the steel pieces, no silver cleaners, no abrasive pastes, no brushes: they're designed for different metals and they scratch the PVD finish.
How to store it
Apart from your other jewellery.
Steel doesn't tarnish: keeping it separate is about stopping different pieces from scratching each other in the same drawer.
Duna, in 925 silver
Duna is in 925 silver, the same as family silverware: it isn't a plating that wears away, it's solid metal.
Over time silver darkens, especially in contact with water, chlorine, salt, perfume and cream. It isn't a defect: just wipe it with a soft silver cloth and it shines again.
Take it off before the shower, the pool and the sea, and store it apart from your other jewellery when you're not wearing it.
If you have sensitive skin
316L steel is the standard choice for people who react to metals, precisely because its nickel release is minimal.
If you've already had reactions to surgical steel, though, write to us before ordering: we'd rather tell you not to buy than deal with a return.
Sizes
Every product page has the exact measurements in the Details and size section, with the manufacturer's figures. They're measured by hand: they can vary by a few millimetres.
