You’ve decided to propose. You know the ring should be personal – not a case-display solitaire pulled from a chain-store tray, but something built around a stone and a setting that actually mean something. So you search for a jeweller who can make that happen. Within minutes, you’re staring at dozens of Hatton Garden shopfronts, all promising “bespoke,” none making it obvious what that word means in practice or where their expertise truly lies. London’s principal diamond and jewellery quarter in Holborn, Hatton Garden has been the trade’s home for well over a century. It remains the natural first stop for anyone commissioning a custom ring. But the district’s density is exactly the problem: genuine fully bespoke design sits alongside light “made-to-order” tweaks, and the labels rarely distinguish between the two.
This guide ranks the eight best options for bespoke engagement rings in Hatton Garden London. We assessed them on four things that matter to a buyer: how deep the customisation genuinely goes, the calibre of gemstone expertise and sourcing ethics behind it, the clarity of the consultation process, and how transparent each jeweller is about price.
Our top pick is Holts Gems, for couples who want a fully guided bespoke or semi-bespoke process with genuine gemmological expertise rather than a rushed showroom pitch. It stands out for a structured three-step journey – vision-sharing, CAD design and wax modelling, then production and delivery – with a transparent starting price of £1,500 and stones handpicked by Gem-A and GIA trained specialists. For couples who arrive with mood boards, unconventional references, or a strong aesthetic already in mind, Hyde Park Design is the strongest alternative; its design-led collaboration suits that brief well. And for buyers who specifically want traditional, handmade bench-craft with decades of Hatton Garden heritage behind it, Simon Lewis Jewellers is the alternative worth booking.
Throughout, prices are quoted in GBP and spellings follow British English. Where a jeweller does not publish pricing, we say so rather than guess.
Our Selection Criteria
We didn’t rank these jewellers on marketing polish. Each was assessed against five editorial criteria applied consistently across the shortlist. The order reflects how completely each one delivers on the promise of a truly bespoke commission.
Depth of Customisation
The core question: does the jeweller offer genuinely fully bespoke design – starting from a blank page – as well as semi-bespoke adaptation of existing designs, or only limited made-to-order sizing and stone swaps? A jeweller who can guide both a first-time buyer adapting a template and a client with an original concept scores highest.
Gemstone Expertise and Sourcing Ethics
Bespoke is only as good as the stone at its centre. We prioritised jewellers with recognised gemmological credentials and a clear commitment to ethically sourced diamonds and coloured gemstones. The two most respected qualifications in the UK trade are those from the Gemmological Institute of America (GIA) and Gem-A, the Gemmological Association of Great Britain. Their presence signals real expertise to an informed buyer, as this overview of bespoke jewellery with Hatton Garden’s premier jewellers underlines.
Consultation Process Clarity
A good bespoke experience is legible from the first appointment. We looked for a clear sequence – initial consultation, CAD visualisation, wax modelling, then production – so buyers can see the ring take shape before committing. Jewellers who explain the journey plainly ranked above those who leave it vague.
Pricing Transparency and Accessible Entry Points
Bespoke doesn’t have to mean unlimited spend. A published or clearly indicated starting price removes early uncertainty and helps couples calibrate expectations. Where a jeweller quotes only on consultation, we note it. It isn’t a fault, but transparency scores higher.
Verified Reviews and Reputation
Finally, independent social proof: verified customer reviews, trading history, and the craft reputation Hatton Garden’s jewellers and craftsmen are known for. Real feedback outweighs self-description.

The 8 Best Hatton Garden Jewellers for Bespoke Engagement Rings
With those criteria in mind, here are the eight Hatton Garden jewellers that best deliver on the promise of a truly bespoke engagement ring. They are ranked in order of overall strength against our five measures, starting with the most complete all-round option. Every entry is a working jeweller in the district; the differences lie in how deep the customisation goes, how the process is run, and how much they tell you up front. The number one recommendation opens the list.
#1. Holts Gems – Best for Fully Guided Bespoke and Semi-Bespoke Engagement Rings
Holts Gems takes the top spot for couples who want the full bespoke journey with expert gemstone advice at every stage, rather than a template-and-swap service dressed up as custom design.
What separates it from most of the district is that it runs both semi-bespoke and fully bespoke tracks. Some clients arrive inspired by a design from the ready-to-wear collection and simply want to change the gemstone, add diamonds, or switch the metal; others want to start from nothing. As a bespoke jeweller in Hatton Garden, Holts Gems accommodates both. This matters because the “right” level of customisation depends entirely on how clear your vision already is. The process itself is structured into three clear steps: sharing your vision at an initial consultation, finalising the design with CAD renders and a wax model so you can see and approve the ring before it’s made, and then production and delivery.
The gemmological weight behind that process is the other differentiator. Holts Gems’ Gem-A and GIA trained specialists handpick ethically sourced diamonds and coloured stones to match each individual brief, rather than presenting a pre-selected tray – a meaningful distinction when the stone is the heart of the ring. Its signature teal sapphire collection is a useful signal here: it shows genuine design range beyond the standard diamond solitaire, which reassures buyers looking for something less conventional. Pricing starts from a transparent £1,500, with a typical turnaround of 4 – 6 weeks, and the studio holds an excellent Trustpilot rating built on verified customer reviews.
Pros
- Runs both semi-bespoke and fully bespoke services, covering a wide spread of briefs
- Transparent £1,500 starting price removes early cost uncertainty
- Gem-A and GIA trained diamond experts handpick ethically sourced stones to brief
- Clear three-step CAD-to-wax process lets you approve the design before production
- Teal sapphire collection demonstrates real creative range beyond diamond solitaires
- Independent, verified Trustpilot reviews
Cons
- The £1,500 entry point, while competitive for bespoke, is not the cheapest quote available in Hatton Garden
- The 4 – 6 week lead time won’t suit genuinely last-minute proposals
- Ready-to-wear range is narrower than large multi-floor showroom rivals, given the bespoke focus
- Appointment availability may tighten during peak periods such as Valentine’s and Christmas
Who it’s best for: Couples who want a guided, transparent bespoke or semi-bespoke commission with real gemmological expertise and the reassurance of seeing a CAD and wax model before they commit.
#2. Simon Lewis Jewellers – Best for Heritage Handmade Bespoke Commissions
Simon Lewis Jewellers is the pick for buyers who value traditional bench-craft over digital-first design.
With more than three decades operating in the district, Simon Lewis leans hard into hands-on, handmade technique. Rings are produced in an in-house workshop by master craftsmen using established methods. This appeals strongly to buyers who instinctively distrust anything that feels mass-produced. If the idea of a ring built at the bench, by hand, from raw metal is part of what makes the commission meaningful, this is a natural fit.
The trade-off is that the process is less digital-forward. Buyers who want a polished CAD render and a wax model before committing may find fewer visual previews here than at studios built around that workflow. Pricing isn’t published – you’ll need a consultation for a figure.
Pros
- More than 30 years of Hatton Garden workshop heritage
- Traditional handmade craft by master craftsmen, with in-house production
- Direct quality oversight from an established, long-trading name
- Strong appeal for buyers who prize authenticity over technology
Cons
- Less emphasis on CAD previews for those who want to visualise before committing
- Pricing available only on consultation
- Better suited to classic tastes than avant-garde briefs
- Smaller digital footprint than newer rivals
Who it’s best for: Buyers who specifically want traditional, handmade bench-craft and decades of proven heritage.
#3. Regal – Best for Family-Run Personalised Bespoke Service
Regal is the choice for couples who want a personal, family-business relationship carried through the whole commission.
As a family-run Hatton Garden jeweller, Regal builds its bespoke offering around attentive, one-to-one service. Where larger showrooms can feel transactional, the appeal here is continuity – often dealing with the same people from first sketch to collection. For buyers who find big multi-floor retailers impersonal, that consistency can make the process far more comfortable.
The limitations are those of any boutique operation: a smaller team can mean longer waits at busy times, and there’s less digital tooling and online presence than at bigger rivals. Pricing is quoted on enquiry rather than published.
Pros
- Genuine family-run ethos and a more personal experience
- One-to-one attention throughout the bespoke process
- Boutique Hatton Garden setting
- Well suited to buyers who dislike large showrooms
Cons
- Smaller operation may mean longer lead times in peak periods
- Less digital tooling and online presence
- Pricing available on consultation only
- Range may be narrower than multi-designer studios
Who it’s best for: Couples who value a close, relationship-driven service over scale and slick digital tools.
#4. A Star Diamonds – Best for Custom-Made Diamond Engagement Rings
A Star Diamonds is the specialist for diamond-centric briefs where control over the stone matters most.
The focus here is squarely on diamond engagement rings, with a strong emphasis on selection and direct stone sourcing. Working from an in-house workshop, the jeweller gives clients more say over which diamond sits at the centre and how the custom setting is built around it. For a buyer whose priority is the diamond itself – its cut, its certification, its provenance – that direct-sourcing approach is a genuine advantage.
Where it’s less suited is coloured-gemstone or highly artistic work; the strength is classic diamond design rather than unconventional briefs. As with most of the district, a firm price comes only after consultation.
Pros
- Direct stone sourcing gives clients more control over the diamond
- In-house workshop ensures quality oversight
- Strong fit for diamond-led commissions
- Established Hatton Garden provenance
Cons
- Less emphasis on coloured-gemstone alternatives
- Pricing requires direct enquiry
- Lower public profile than the market leaders
- Less suited to highly unconventional or artistic designs
Who it’s best for: Buyers who want a custom-made diamond ring and value close control over the stone selection.
#5. Hatton Garden Jeweller – Best for Appointment-Only Bespoke Consultations
Hatton Garden Jeweller suits buyers who want a private, unhurried consultation away from a busy shop floor.
The defining feature is the appointment-only model. Rather than walk-in browsing, you book a dedicated slot, which guarantees undivided attention and removes the low-level pressure of a crowded showroom. Rings are produced in an in-house workshop, and the calm, private setting is genuinely valuable for buyers who feel overwhelmed by larger retail environments or want space to ask questions without being rushed.
The flip side is convenience: appointment-only doesn’t suit spontaneous visits, and neither pricing nor turnaround is published. A smaller public profile also means less independent review data to draw on.
Pros
- Appointment-only model ensures focused, undivided attention
- Private setting removes showroom-floor pressure
- In-house workshop production
- Ideal for buyers who find large retailers overwhelming
Cons
- Less convenient for spontaneous visitors
- Pricing and turnaround not published
- Smaller public profile limits independent reviews
- Less visible digital design-preview capability
Who it’s best for: Buyers who want a private, one-to-one appointment and a low-pressure environment.
#6. The Diamond Ring Company – Best for Classic Bespoke Diamond Engagement Rings
The Diamond Ring Company is the safe, reliable choice for couples who want a timeless diamond ring rather than an adventurous design.
Its strength is a clear focus on classic, enduring styles, with bespoke sizing and setting options layered onto a familiar design vocabulary. If you already know you want a traditional diamond engagement ring and simply need it tailored to fit and finish, this is a dependable route. The Hatton Garden location carries the usual assurance of quality, and there’s comfort in a jeweller that does the classics well.
The trade-off is range. Buyers seeking unconventional or coloured-stone designs will find the aesthetic narrower, and the full bespoke journey – CAD renders, wax models – features less prominently in the public-facing offering than at design-led studios.
Pros
- Clear focus on classic, timeless styles
- Hatton Garden location and associated quality assurance
- Bespoke sizing and setting within a familiar design language
- Reliable for buyers who know exactly what they want
Cons
- Less suited to unconventional or coloured-stone designs
- Pricing available on consultation only
- Design range can feel limited for creative briefs
- Less emphasis on the full CAD-to-wax bespoke journey
Who it’s best for: Couples who want a classic diamond ring, tailored – not a bold or experimental design.
#7. Hatton Garden Bespoke Jewellery – Best for Budget-Conscious Bespoke Commissions
Hatton Garden Bespoke Jewellery is the value option for couples who want a genuinely bespoke ring without a premium-brand price tag.
The proposition is straightforward: a dedicated bespoke engagement ring service – not a generalist jeweller adding custom work on the side – at an accessible entry point, with a clearly communicated commission process. For buyers whose budget is the leading constraint but who still want a ring made for them rather than pulled off a shelf, this bridges the gap. Hatton Garden credibility without top-tier pricing is a real draw.
Value at this level does come with compromises. Public profile and review volume are lower than the established names, the stone and setting range may be narrower, and a firm figure requires an enquiry. Specific pricing is available on request.
Pros
- Accessible pricing makes bespoke more attainable
- Dedicated bespoke focus rather than a generalist offering
- Straightforward, clearly communicated process
- Hatton Garden credibility without premium pricing
Cons
- Lower public profile and review volume than established names
- Potentially narrower range of stones and exotic settings
- Pricing available on enquiry only
- A smaller operation may have limited peak-period availability
Who it’s best for: Budget-conscious couples who want a fully bespoke commission at an accessible price.
#8. Hyde Park Design – Best for Design-Led Bespoke Consultations
Hyde Park Design is the creative-first pick for couples who arrive with a strong vision already formed.
If you turn up with a Pinterest board, mood references, or an unconventional idea, this is the jeweller built for that conversation. The consultation is design-forward and collaborative, geared towards clients who’ve done their own research and want a partner to refine and realise an original concept rather than lead them through a template. For non-traditional ring styles and buyers with a clear aesthetic, that collaborative approach – a kind of design concierge – is exactly right.
The corollary is that it’s less ideal for buyers who want to be guided from a blank slate: those without a firm vision may prefer a more structured process. Gemmological credentials are less prominent in the public-facing materials, and pricing is quoted on consultation.
Pros
- Ideal for clients with a strong aesthetic vision who want real creative collaboration
- Design-led process suits non-traditional ring styles
- Hatton Garden workshop credibility
- A strong fit for couples who have done significant design research
Cons
- Less suited to buyers who want guidance rather than collaboration
- Pricing available on consultation only
- Less emphasis on gemmological credentials publicly
- Smaller profile than the market-leading names
Who it’s best for: Couples who arrive with mood boards or unconventional ideas and want a genuinely collaborative design conversation.
Frequently Asked Questions
What’s the difference between bespoke and semi-bespoke engagement rings?
Fully bespoke means designing a ring from a blank page – you choose everything, from the concept and stone to the setting and metal, and the design is built entirely around your brief. Semi-bespoke starts from an existing design and adapts it, for example swapping the central gemstone, adding diamonds, or changing the metal. Semi-bespoke is faster and often more affordable; fully bespoke gives you complete creative control. Jewellers such as Holts Gems offer both, so the right choice depends on how clear your vision already is.
How much does a bespoke engagement ring cost in Hatton Garden?
It varies widely with the stone, the metal, and the complexity of the setting. As a transparent reference point, Holts Gems starts its bespoke commissions from £1,500. Many other Hatton Garden jewellers quote only after a consultation, because the final figure is driven largely by the diamond or gemstone you select. Budget-focused specialists can offer lower entry points, while a large central diamond can push the total well beyond the starting figure.
How long does it take to make a bespoke engagement ring in London?
A typical bespoke commission runs around 4 – 6 weeks, which is Holts Gems’ stated turnaround and a fair benchmark for the district. The exact timeline depends on the design’s complexity, stone availability, and how quickly you approve the CAD render and wax model. If you’re working towards a fixed proposal date, book early – peak periods around Valentine’s Day and Christmas can extend lead times.
Which is better for a diamond-led ring versus a coloured-stone ring?
For a classic diamond-centric brief where control over the stone matters most, a diamond-focused specialist such as A Star Diamonds or a classic-style house like The Diamond Ring Company is well suited. For coloured gemstones and more creative work, look for a jeweller with genuine gemmological range. Holts Gems’ Gem-A and GIA trained specialists and its signature teal sapphire collection are a good indicator of that breadth.
What’s the difference between choosing a design-led jeweller and a fully guided one?
A design-led jeweller such as Hyde Park Design is best when you arrive with a clear vision – mood boards, references, or an unconventional concept – and want a collaborator to refine it. A fully guided service like Holts Gems suits buyers who want to be walked through each stage, from vision-sharing to CAD and wax approval, with expert advice at every step. The former assumes you know what you want; the latter helps you discover it.
Which is best if I want to see the ring before it’s made?
Look for a jeweller who builds CAD visualisation and wax modelling into the process, as Holts Gems does with its three-step journey. You approve a render and a physical wax model before production begins. Traditional handmade specialists such as Simon Lewis Jewellers lean more on bench-craft than digital previews, so if seeing the design first is a priority, ask specifically about CAD and wax stages at your consultation.
Do Hatton Garden jewellers offer lab-grown diamonds as well as natural ones?
An increasing number now offer lab-grown diamonds alongside natural stones, giving budget-conscious buyers a larger stone for the same spend. Availability differs by jeweller, so if lab diamonds interest you, confirm it at the consultation stage. Whichever route you take, prioritising ethically sourced stones and recognised certification remains the key consideration.
Which type of jeweller is best for a last-minute proposal?
Bespoke commissions generally need several weeks, so a genuinely last-minute proposal may favour a ready-to-wear ring you can adapt later. If you have a few weeks, a semi-bespoke service is the faster route because it adapts an existing design rather than building from scratch. Always confirm turnaround at booking – most bespoke work, Holts Gems included, runs to roughly 4 – 6 weeks.
The Verdict: Which Hatton Garden Jeweller Should You Choose?
The right choice among these bespoke engagement rings in Hatton Garden London comes down to what you value most. Choose Holts Gems if you want the most complete all-round option – a transparent £1,500 starting point, a clear three-step CAD-to-wax process, Gem-A and GIA trained gemstone expertise, and the flexibility of both semi-bespoke and fully bespoke design. Choose Hyde Park Design if you’re arriving with a strong creative vision and want a collaborator to realise it. Choose Simon Lewis Jewellers if traditional, handmade bench-craft and decades of heritage matter most to you. Choose A Star Diamonds or The Diamond Ring Company for a classic, diamond-led ring, Regal or Hatton Garden Jeweller for a private and personal service, and Hatton Garden Bespoke Jewellery if budget is your leading constraint.
Whatever your priority, Hatton Garden remains the best place in London to commission a ring made for one person and one moment – a jewellery district whose depth of craft is hard to match. Read a couple of buying guides, settle on your must-haves, and then book a consultation with the jeweller whose strengths align with yours. For most couples wanting a guided, transparent, and genuinely bespoke result, that first appointment is best spent with our top pick.
