Waterproof Necklaces That Stay On Through Everything

Most UK waterproof necklace collections stop at twenty generic chains. Moonela runs over seventy, because staying-on should not mean picking from the same five pendants. Names, initials, birthstones, tennis chains, pear solitaires, arabic calligraphy, zodiac signs, angel numbers, heart charms, multi-name bars. Every piece is Premium 18K Gold Plated over 316L stainless steel, engraved or sculpted into the metal rather than stamped on top. The gold is real gold, the waterproof rating is real, and the seventy-plus styles mean the right necklace exists for the right wrist and the right kind of day.

Personalised, Not Just Waterproof

Nearly every waterproof necklace on the UK market is generic, a chain or a pendant with no personal mark. Moonela layers real personalisation on top. Pair a waterproof chain with your own name (the Name Plate, the Bubble 3D, the Bar, the Handwritten Signature), with your initial (the Cuban Link, the Curb Chain, the Pearl, the Clover Enamel), with your birthstone (twelve months available), or with your country on a Map Necklace, your zodiac sign, or an angel number. The personalisation is engraved, sculpted or hand-drawn into the gold, not surface-printed, so it does not wash off.

18K Premium Gold Plated, Not PVD Coating

The industry standard for waterproof jewellery in the UK is PVD coating over stainless steel. It works, but it is thin. Moonela uses Premium 18K Gold Plated, a real heavier layer of 18K gold bonded over 316L stainless steel. Every necklace is hypoallergenic and tarnish-free, rated for shower, pool, sea, sweat and sleep. Wear yours to a long day, through a workout, into bed. The gold does not peel, the setting does not rust, the engraving does not fade. Most pieces come with a lifetime warranty on plating and quality.

Pair It With Its Bracelet, Earrings or Ring

A waterproof necklace rarely wears alone. Match yours with our Waterproof Bracelets to build a full keep-it-on stack, or extend with Tarnish-Free Jewellery across earrings and rings. If the personalisation is the reason you are here, pair the waterproof necklace with a matching Personalised Necklace layered at a different height. Pieces that stay on should not feel like they are cohabiting by accident.

Looking for a waterproof initial necklace or a waterproof personalised necklace? Every letter and name piece here is engraved before production and sealed in the same PVD build.

FAQ

Frequently Asked Questions

Are these waterproof necklaces really waterproof?
Yes. Every Moonela necklace uses 18K gold PVD coating bonded to surgical-grade 316L stainless steel. The PVD process creates a molecular bond, not a surface plating, so you can shower, swim, sweat and sleep without fear of fading or tarnishing.
Can I personalise a waterproof necklace?
Most of our waterproof necklaces are available with custom names, initials or birthstones. Look for "Personalised" in the product title or check our personalised jewellery collection for the full range.
What chain length should I order?
Standard length is 16-18 inches (40-45 cm), which sits at the collarbone on most adults. Need a longer chain for layering or a longer drop? Many pieces have a length selector. If unsure, contact us and we will help you size correctly.
Will the gold turn green or stain my skin?
No. We use surgical-grade 316L stainless steel as the base, never cheap nickel, so Moonela necklaces are hypoallergenic and will not react with your skin.
Can I wear my waterproof necklace 24/7?
Absolutely. They are designed for everyday wear: shower, swim, work out, sleep. The PVD finish is the same one used in luxury Swiss watchmaking, engineered for daily wear.
What is your return policy if it does not fit?
30-day free returns on all UK orders for non-personalised items. See our returns policy for full details.
