Your engagement ring or wedding band has seen better days. Daily wear, hand cream, and the occasional splash of washing-up liquid can dull even the most brilliant diamond. Finding a reliable jewellery cleaning service London residents trust is essential for keeping your precious pieces looking their best.

Whether you’re dealing with tarnished silver, a cloudy diamond, or a treasured heirloom that needs expert attention, professional cleaning can make a remarkable difference. Hatton Garden, London’s historic jewellery quarter, is home to some of the most skilled craftsmen in the country, many of whom offer cleaning and restoration services alongside their design work.

At A Star Diamonds, we include lifetime cleaning and polishing as a complimentary benefit for all our bespoke engagement rings and wedding bands. But we know not everyone’s jewellery comes from us, so we’ve put together this guide featuring the five best options across London for professional jewellery cleaning in 2026.

1. A Star Diamonds Hatton Garden

Based in the heart of Hatton Garden, A Star Diamonds offers a comprehensive jewellery cleaning service London shoppers and locals rely on for engagement rings, wedding bands, and fine jewellery. You’ll find expert goldsmiths and gemologists on site who handle everything from routine maintenance to more complex restoration work.

What they clean and what they may refuse

A Star Diamonds accepts all precious metals, including platinum, gold (white, yellow, and rose), and silver pieces. They clean diamond jewellery, gemstone rings, and most fine jewellery items. However, they may advise against cleaning extremely fragile vintage pieces or costume jewellery with unstable settings, as the ultrasonic process could cause damage.

How their cleaning and polishing process works

The team uses professional ultrasonic cleaners combined with steam cleaning to remove built-up dirt and oils from your jewellery. They follow this with careful hand polishing using specialist cloths and compounds to restore the metal’s original shine. Each piece receives individual attention rather than batch processing.

"Professional ultrasonic cleaning reaches areas you simply cannot clean at home, particularly underneath stone settings and in intricate metalwork."

Inspection and aftercare for engagement rings

During each clean, the goldsmith inspects your engagement ring’s prongs and settings for signs of wear or loosening. They’ll alert you to any potential issues before stones become at risk. You receive guidance on home care between professional cleanings.

Turnaround times and how to book in London

Most cleaning appointments take 30 to 45 minutes if you wait, or you can drop off your jewellery for same-day collection. Book an appointment online or call ahead to secure your preferred time slot at their Hatton Garden workshop.

Pricing and lifetime benefits to ask about

Customers who purchased their engagement rings or wedding bands from A Star Diamonds receive lifetime complimentary cleaning and polishing as standard. For jewellery purchased elsewhere, expect to pay around £25 to £50 depending on the piece’s complexity and condition.

2. Hatton Garden Workshop

Hatton Garden Workshop operates as an independent jewellers specializing in repairs and restoration alongside their cleaning services. Their team handles everything from routine maintenance to complex gemstone work, making them a solid choice for pieces that need more than a basic polish.

What they clean and what they may refuse

The workshop accepts gold and platinum jewellery along with silver pieces requiring professional attention. They clean gemstone rings, necklaces, and bracelets, but exercise caution with porous stones like pearls, opals, and turquoise. Costume jewellery with glued elements typically receives refusal, as their cleaning methods could damage the adhesive bonds.

How their cleaning and polishing process works

Your jewellery undergoes ultrasonic cleaning followed by steam treatment to remove stubborn residue from crevices. Craftsmen then hand-polish each piece using specialized compounds matched to your metal type. This multi-step approach ensures thorough cleaning without compromising delicate details.

Inspection and aftercare for gemstone jewellery

During the cleaning appointment, their gemologist examines stone security and checks for chips or scratches. You receive advice on proper storage and which household products to avoid. They’ll recommend follow-up appointments if your stones show signs of loosening.

"Regular professional inspection catches problems before you lose a precious stone, saving you considerable replacement costs."

Turnaround times and how to book in London

Walk-in appointments take approximately one hour for standard cleaning. You can also arrange drop-off service with next-day collection. Call ahead during busy periods to secure your spot.

Pricing and what drives the cost

Basic cleaning starts around £30 for simple pieces, while intricate designs with multiple stones cost closer to £60. Pricing depends on metal type, piece complexity, and whether you need additional repairs alongside your clean.

3. Johnsons Jewellers

Johnsons Jewellers operates as an established independent workshop offering a comprehensive jewellery cleaning service London customers use for both routine maintenance and specialized restoration. Their team handles everything from basic polishing to full refinishing work.

What they clean and what they may refuse

The workshop accepts precious metal jewellery including gold, platinum, and silver pieces. They clean diamond rings and gemstone necklaces, but pieces with unstable settings or delicate antique constructions may require assessment before they accept the work.

How their in-house cleaning, polishing, and refinishing works

Your jewellery receives ultrasonic cleaning to remove built-up residue, followed by professional polishing using grade-specific compounds. For pieces showing significant wear, they offer refinishing services that restore the metal surface through careful buffing and re-texturing. Each process takes place entirely in-house rather than being outsourced.

When to choose refinishing over a basic clean

Deep scratches, worn prongs, or tarnished surfaces that cleaning alone cannot fix require refinishing. Consider this option when your jewellery has lost its structural integrity or shows visible damage beyond surface dirt.

"Refinishing rebuilds the metal surface, addressing scratches and wear that simple cleaning cannot resolve."

Turnaround times and how to arrange drop-off

Standard cleaning completes within two to three days of drop-off. Refinishing work extends this timeframe to one to two weeks depending on complexity. Call ahead or visit their workshop directly to arrange your drop-off appointment.

Pricing expectations and common add-ons

Basic cleaning costs approximately £35 to £45 for most pieces. Refinishing services start around £60 and increase based on metal type and damage extent. Common add-ons include prong tightening and minor repairs discovered during inspection.

4. Mappin & Webb

Mappin & Webb operates as a luxury jeweller with multiple locations across London, offering professional cleaning services for fine jewellery and timepieces. Their heritage brand status means you receive service from craftsmen trained to handle high-value pieces with exceptional care standards.

What they clean and what they may refuse

Mappin & Webb accepts precious metal jewellery including platinum, gold, and silver items from any designer or maker. They clean diamond pieces, gemstone rings, and luxury watches, but delicate vintage items may require specialist assessment. Costume jewellery typically falls outside their service remit.

How their jewellery cleaning service works

Your jewellery undergoes professional ultrasonic cleaning followed by careful hand polishing using luxury-grade materials. Their craftsmen inspect each piece during the process to identify potential issues requiring attention.

Annual cleaning and inspection for fine jewellery

Mappin & Webb recommends yearly professional cleaning for frequently worn pieces. Each appointment includes a thorough inspection of settings, prongs, and metal condition to catch wear before damage occurs.

"Annual professional maintenance prevents costly repairs and keeps your investment pieces in optimal condition."

Turnaround times, locations, and appointment options

Cleaning appointments at their Regent Street or Sloane Street boutiques typically complete within one hour if you wait. Book appointments online or call ahead to secure your preferred time slot.

Pricing and what affects premium service costs

Expect to pay between £40 and £80 for standard cleaning. Complex pieces or those requiring additional inspection work cost more, reflecting their specialist expertise and premium service standards.

5. H Samuel

H Samuel operates as a high-street jeweller with stores across London, offering accessible cleaning services alongside their retail and repair operations. Their widespread presence makes them a convenient option when you need a jewellery cleaning service London locations offer without travelling to specialist quarters like Hatton Garden.

What they clean and what they may refuse

H Samuel accepts gold, silver, and platinum jewellery from any retailer, including engagement rings and wedding bands. They clean diamond pieces and most gemstone jewellery, though extremely delicate vintage items or those with unstable settings may require assessment before acceptance.

How cleaning fits into repairs and resizing services

Your jewellery receives professional cleaning as part of their broader workshop services. When you bring items for resizing or repair work, cleaning typically occurs during the same appointment, making it efficient for pieces needing multiple services.

What to check before handing over stone-set rings

Examine your ring’s prong security and note any loose stones before handing it over. Document existing scratches or damage to avoid disputes, and remove any sentimental items you cannot risk losing during the cleaning process.

"Documenting your jewellery’s condition before service protects both you and the jeweller if complications arise."

Turnaround times and how to book or walk in

Most stores accept walk-in appointments for cleaning consultations. Standard cleaning completes within one to two weeks, though in-store services may offer faster turnaround during quieter periods.

Pricing and when cleaning may be included

Basic cleaning costs approximately £20 to £40 depending on piece complexity. Jewellery purchased from H Samuel often includes complimentary cleaning as part of their aftercare service, so check your purchase documentation before paying.

Choosing the right cleaner

Your choice of jewellery cleaning service London depends on several factors, including your piece’s value, metal type, and any gemstones requiring specialist attention. Consider whether you need simple maintenance or more extensive restoration work, as this affects both cost and turnaround time.

Location and convenience matter when you own jewellery needing regular attention. Hatton Garden workshops offer concentrated expertise, while high-street options provide easier access across multiple London locations. Check whether your jeweller includes lifetime cleaning benefits with original purchases, as this saves considerable money over years of ownership.

Professional cleaning extends your jewellery’s life and maintains its appearance between major services. Your engagement ring deserves expert care from craftsmen who understand precious metals and gemstone security. A Star Diamonds offers complimentary lifetime cleaning and polishing for all bespoke pieces we create, plus professional cleaning services for jewellery from any source. Book your appointment at our Hatton Garden workshop to restore your jewellery’s original brilliance.
