Why it lasts

The coating that changes everything

Most jewellery fails in 6–12 months. Here’s why ours doesn’t.

  • 2-Year Warranty

    If it fades, tarnishes, or turns green within two years — we replace it. Free. No forms, no fine print.

  • Ocean Safe

    Swim, shower, sweat. The PVD seal bonds at the molecular level — salt water, chlorine, sweat. Nothing breaks it down.

  • Never Tarnish

    PVD coating doesn’t sit on top of the metal — it bonds into it. That’s why it doesn’t wear off when everything else does.

  • Hypoallergenic

    Nickel-free surgical steel — the same grade used in medical implants. Women with severe metal sensitivities wear it 24/7.
