Why it never tarnishes
Gold that's bonded, not brushed on.
PVD (physical vapor deposition) fuses a layer of real 18k gold to surgical-grade steel under high heat and pressure. The bond is molecular. It can't flake or wash off like plating. That's why Costiera survives the sea, the sun, and years of daily wear.
- Real 18k gold surface
- Pressure-bonded with PVD
- Waterproof, hypoallergenic, tarnish-proof
La Promessa
If it ever loses its shine, we replace it.
Every piece is backed by our 1-year shine guarantee. If your jewelry dulls, we'll replace it.
Wear them together
La Costiera Stack
Three pieces, layered like light on the water — a chain, a pendant, and a pearl drop. Worn together or apart. Always waterproof.

About us
Born on the Amalfi coast.
Costiera began with a simple frustration: gold can't touch water.
We built jewelry for the way the coast actually lives. Golden hour swims, salt air, lemon groves, long warm nights. Gold you never have to take off.
