Choosing a bespoke engagement ring London jeweller is one of the most personal decisions you’ll make during the proposal process. Unlike picking a ring off a shelf, going bespoke means working directly with designers and craftspeople to create something that reflects your relationship, not someone else’s template.

London’s Hatton Garden has been the centre of the UK jewellery trade for over a century, and it remains the best place to find skilled jewellers who specialise in custom ring design. But with so many studios and workshops to choose from, it helps to know which ones are genuinely worth your time, especially when you’re investing in something this meaningful.

As a family-run jeweller based in Hatton Garden, we at A Star Diamonds work alongside goldsmiths, designers, and gemologists every day to craft bespoke engagement rings. That experience gives us a clear view of what good craftsmanship looks like, and who else in London is doing it well. Below, we’ve put together six jewellers worth visiting in 2026, including what each one does best and what kind of buyer they’re suited to.

1. A Star Diamonds

A Star Diamonds is a family-run jeweller based in Hatton Garden, and we specialise in crafting bespoke engagement rings from scratch. Our team includes goldsmiths, designers, and gemologists who guide you from the first conversation through to the finished piece. Every ring we make is crafted in the UK, and we back that with lifetime benefits including free resizing, polishing, and cleaning.

Design style and stone options

Our design approach covers classic solitaires, hidden halos, and diamond bands, as well as fully custom designs built around your vision. You can choose from ethically sourced natural diamonds or 100% conflict-free lab-grown diamonds, depending on your priorities around budget and sourcing. Both options come with full traceability and expert guidance on the 4Cs.

How the bespoke journey works

The process starts with a free consultation where you share your ideas, budget, and any inspiration you have. From there, our designers produce detailed drawings before our goldsmiths begin the physical work. You’re involved at every stage, which means the final ring genuinely reflects what you asked for.

This level of involvement is particularly valuable if you want a bespoke engagement ring London jewellers with a high-street presence simply cannot produce.

The key stages run as follows:

• Initial consultation to discuss your vision and budget
• Design drawings from our in-house team
• Stone selection with gemologist guidance
• Handcrafting by our London goldsmiths
• Final review before collection

Pricing and typical budgets

Bespoke rings at A Star Diamonds start from around £1,500, though most clients invest between £3,000 and £8,000 depending on diamond grade, metal type, and design complexity. Lab-grown diamonds allow you to reach a larger stone within the same budget.

Appointments and location

We’re based in Hatton Garden, London, and you can book a consultation online or contact us directly via phone or WhatsApp. Remote consultations are available if you can’t visit in person.

Good to know before you go

A Star Diamonds includes complimentary engraving on every ring, alongside lifetime resizing and cleaning at no extra charge. These benefits apply to every purchase, so your ring stays in the best possible condition long after the proposal.

2. 77 Diamonds

77 Diamonds is a London-based jeweller with a strong online platform and a wide inventory of loose diamonds and settings. They appeal to buyers who want to research and compare stones in detail before committing to a design, making them a practical choice if you like doing your homework first.

Design style and stone options

Their range covers classic solitaires through to more intricate multi-stone designs, with thousands of diamonds available to browse online. You can filter by cut, colour, clarity, and carat to narrow your selection before any consultation takes place.

How the bespoke journey works

77 Diamonds structures the process around choosing your stone first, then building or customising a setting around it. Their team guides you through both steps, either online or in person.

This stone-first approach works well if you already have a clear idea of the diamond size or shape you want.

You can begin the entire process remotely through their website, which gives you a detailed view of available inventory before you visit the showroom.

Pricing and typical budgets

Rings typically start from around £1,000, with most bespoke commissions falling between £2,500 and £6,000 depending on the stone grade and setting complexity.

Appointments and location

Good to know before you go

If you’re comparing bespoke engagement ring London options and want maximum transparency on diamond pricing upfront, 77 Diamonds delivers that through their detailed online stone search tool before your first conversation with their team.

3. London Victorian Ring Co

London Victorian Ring Co is a specialist jeweller focused on antique-inspired and vintage-style engagement rings. If your partner gravitates toward intricate detailing and period aesthetics, this studio offers something genuinely different from the clean lines of contemporary design.

Design style and stone options

Their work draws heavily from Victorian, Edwardian, and Art Deco design periods, featuring milgrain edges, filigree work, and rose-cut diamonds. You can choose from old-cut natural diamonds or coloured gemstones, which pair naturally with the vintage aesthetic they specialise in.

How the bespoke journey works

The bespoke process starts with a consultation where you discuss the period and style that resonates with your partner. Their team then designs a ring that captures that era faithfully, using traditional techniques alongside modern craftsmanship standards.

This approach suits buyers who want a bespoke engagement ring London jewellers with a strictly modern focus simply will not produce.

Pricing and typical budgets

Bespoke commissions typically start from around £2,000, with most clients spending between £3,500 and £7,000 depending on stone choice and design intricacy.

Appointments and location

They operate from Hatton Garden, London, and you can book appointments directly through their website.

Good to know before you go

If your partner loves history and heritage, this jeweller brings genuine period expertise to every commission rather than simply copying antique styles from a catalogue.

4. Bobby White

Bobby White is a Hatton Garden jeweller known for producing handcrafted rings with a distinctly personal feel. Their studio takes on a limited number of commissions at a time, which means each client gets focused attention throughout the design and making process.

Design style and stone options

Bobby White leans toward clean, contemporary designs that let the stone take centre stage, though they also produce more detailed settings on request. You can work with natural diamonds, coloured gemstones, or alternative stones depending on the look you’re after.

How the bespoke journey works

The process begins with a one-to-one consultation where you walk through your ideas and preferences in detail. Their maker then works closely with you through each stage, from sketches to the finished ring.

For buyers seeking a genuinely handmade bespoke engagement ring London studio with close maker involvement, Bobby White delivers that in a way larger operations often cannot.

Pricing and typical budgets

Commissions typically start from around £2,000, with most clients investing between £3,000 and £7,000 depending on stone grade and design detail.

Appointments and location

Bobby White operates from Hatton Garden, London, and appointments can be booked through their website.

Good to know before you go

Their limited commission intake means lead times can be longer, so book your consultation early if you have a firm proposal date in mind.

5. The Cut London

The Cut London is a modern jeweller built around transparency and ethical sourcing, making them a strong option for buyers who want a clear breakdown of costs and full visibility on where their diamond comes from. Their approach strips away the mystique that often surrounds fine jewellery and replaces it with straightforward, informed decision-making.

Design style and stone options

Their design range leans toward clean, contemporary styles that let the stone carry the ring rather than complex metalwork. You can select from ethically sourced natural diamonds or lab-grown alternatives, with traceability provided across both options and expert guidance on cut quality throughout.

How the bespoke journey works

Each commission begins with a structured consultation covering your design preferences, stone priorities, and budget in detail. From there, their team moves through stone selection and setting design with you before any production starts.

This methodical process makes The Cut London a solid bespoke engagement ring London option if you want defined stages and no ambiguity at any point.

Pricing and typical budgets

Rings typically start from around £1,500, with most bespoke commissions sitting between £3,000 and £7,000 depending on stone specification and setting complexity.

Appointments and location

The Cut London is based in Marylebone, London, and you can book a consultation directly through their website.

Good to know before you go

Their pricing structure is itemised by design, so you receive a clear split between stone and setting costs before you commit to moving forward.

6. De Beers London

De Beers is the most recognised name in diamonds globally, and their London flagship on New Bond Street brings that heritage directly into a bespoke engagement ring service. If provenance and prestige carry weight for you, this is the most established name on this list.

Design style and stone options

De Beers works primarily with natural diamonds, which sit at the heart of every design they produce. Their aesthetic leans toward elegant, timeless settings that reflect their position as a heritage diamond house rather than a trend-led studio.

How the bespoke journey works

Their bespoke service pairs you with a dedicated consultant who guides your stone selection and setting design from start to finish. You work directly with their in-house design team to shape a ring that meets your exact specifications.

For buyers seeking a bespoke engagement ring London option with unmatched brand heritage behind every stone, De Beers offers a genuinely distinct experience.

Pricing and typical budgets

De Beers sits firmly at the premium end of the market, with bespoke commissions typically starting from £5,000 and rising considerably depending on stone size and design complexity.

Appointments and location

Their flagship store sits on New Bond Street, London, and you can book a consultation directly through their website.

Good to know before you go

De Beers works exclusively with natural, traceable diamonds, so if a lab-grown stone is part of your brief, you will need to look elsewhere on this list.

Next steps

Each jeweller on this list brings something different to the table, so the right choice depends on your priorities, whether that’s heritage, transparency, vintage style, or a fully personal bespoke journey from start to finish. If you know your partner’s taste and have a rough budget in mind, you already have enough to start a conversation with any of the studios above.

Finding a bespoke engagement ring London jeweller is a meaningful step, and the best way to move forward is to book a consultation rather than spend more time browsing.
