Simi Jewellery

Tarnish-Proof 18K Gold Jewellery, Made to Last

Beautiful jewellery shouldn't come with a list of warnings. Every piece at Simi Jewellery is 18K gold, tarnish-proof, and fully waterproof, designed for women who want to put it on once and forget about it. Shower in it, swim in it, sleep in it. No green skin, no fading, no fuss.

We believe everyday luxury should be accessible, not aspirational. That's why every bracelet, necklace, earring, and ring in our collection is priced to wear daily, not save for "special occasions," backed by a lifetime guarantee, because jewellery that doesn't last isn't really affordable at all.

Why Choose Simi Jewellery

Tarnish-Proof & Waterproof Every piece is built to handle real life — sweat, showers, perfume, the lot. No more taking jewellery off before bed.

18K Gold, Not Plated Steel. Where most "affordable" tarnish-free jewellery uses gold-coated stainless steel, we use genuine 18K gold for a richer colour and longer-lasting finish.

Lifetime Guarantee: If it tarnishes, we replace it. Simple as that.

Designed & Shipped from the UK. Fast UK delivery, free over £50, with worldwide shipping available.

Our Story

SIMI Jewellery was born out of a personal search for jewellery that's beautiful and built to last — without the price tag or the care instructions. Every piece is designed to be worn every day, in real life, by real women.
