Most gold jewelry has a shelf life. A few showers, a swim, a summer of sweat, and the plating starts to fade or turn your skin green. Waterproof jewelry is built differently — a solid base of 316L stainless steel under thick 18k gold, sealed so water, soap, and sunscreen have nothing to eat away at.
The short version: you put it on, and you stop thinking about it. That's the whole point.
Every design starts on paper, pinned to the wall until it earns its place. Before a piece like the Nassau Necklace ever gets made, we're arguing over chain weight, clasp strength, and how the gold will hold up after a year of real wear. Designing for longevity isn't a step at the end. It's the first question we ask.
316L stainless steel core — the same grade used in surgical tools, so it won't rust or bend out of shape.
Thick 18k gold layer — real gold pressed on heavy, not a thin flash that rubs off in weeks.
Sealed against water — showers, saltwater, sweat, and sunscreen all leave the color exactly where it was.
Beach mornings, dishes, the gym, deep sleep. The Nassau keeps its shine through every one of them.
If your piece ever loses its color or finish under normal wear, we'll replace it. We can offer that because we know exactly what goes into every design and exactly how long it holds up. This is the commitment behind the question we asked on that studio wall.
