At House of Carats, we believe luxury shouldn't come with a hefty price tag. While some brands markup 8-10x, we keep it fair by selling directly to you. Over 60,000 customers already know the secret — The Diamond Look for Less.

We recycle excess and craft each piece to order, cutting waste and extra costs so you only pay for what truly matters: stunning jewellery at honest prices.

Why we're different

Unmatched Affordability: While many brands markup prices by 8-10x, we offer fair, affordable pricing directly to you.

Unrivaled Diamond Simulants: Our advanced crushed ice cut technology mimics real diamonds, earning us a feature in British Vogue.

Gentle on Your Skin: Nickel-free, hypoallergenic jewellery ensures comfort without irritation.

Conscious Commitment: We prioritise sustainability, recycling pieces and producing small batches to reduce waste, aiming for 100% recyclable metals.

We think you'll love...

You might wonder...

Absolutely not - we only use high quality metals and no toxic substances such as cadmium or nickel.

Each piece is meticulously crafted by a skilled professional, but we know that accidents happen. Your purchase is covered by warranty so you can rest assured.

All our jewelry is made with hypoallergenic metals (and absolutely no nickel). We offer hypoallergenic brass pieces that are finished in 18k gold, solid .925 sterling silver and vermeil (which is .925 sterling silver plated in 18k yellow gold) options.

Our sparkly Diamond Simulant stones are created using world class crushed-ice cutting technique on high-carbon stones, emulating the look of real diamonds. They're an affordable alternative that allows us to feel safe in public spaces, without compromising our values or budgets.

We offer a 30-day return window and complimentary exchanges on all eligible items. To qualify, pieces must be unused, in their original condition, and returned with all tags attached. Please note, custom-made items and pierced jewellery are excluded for hygiene and bespoke reasons.

All orders over £50 benefit from free shipping. Additional delivery information and express options are available at checkout.
