If you’ve searched for A Star Diamonds Hatton Garden, you’re probably weighing up where to buy one of the most important pieces of jewellery you’ll ever own. That’s a decision worth getting right, and it starts with knowing exactly who you’re working with.

A Star Diamonds is a family-run jeweller based in Hatton Garden, London’s historic diamond quarter. We specialise in bespoke engagement rings and wedding bands, designed and crafted in-house by our team of goldsmiths, designers, and gemologists. Every ring we make is shaped around the person wearing it, not pulled from a catalogue.

This article breaks down what we actually do, how our bespoke design process works from first consultation to finished ring, and what our customers have to say about the experience. We’ll cover our approach to ethically sourced diamonds (both natural and lab-grown), the lifetime benefits that come with every purchase, and the practical details, like how to book an appointment and what to expect when you visit our Hatton Garden workshop. Whether you’re early in your research or ready to start designing, this should give you everything you need to decide if we’re the right fit.

What A Star Diamonds in Hatton Garden offers

A Star Diamonds Hatton Garden is not a general jeweller selling off-the-shelf rings. Every piece we create starts from a blank canvas, shaped by your preferences, your budget, and the story behind your relationship. Our team includes goldsmiths, designers, and gemologists who work together under one roof, so every decision, from metal choice to stone selection, gets the attention it deserves. That combination of in-house expertise means you are not passing your brief through a middleman.

Bespoke engagement rings and wedding bands

Bespoke means genuinely custom, not just picking a size or engraving a name. You choose the metal type (white gold, yellow gold, rose gold, or platinum), the setting style, the stone shape, and the finishing details. We can adapt one of our existing styles or start completely from scratch if you have something specific in mind.

Working with a jeweller who designs and makes in-house means you get one clear point of contact from first conversation to final collection, which reduces the risk of miscommunication and unwanted surprises.

Our core ring styles include:

• Solitaire – a classic single-stone setting that puts the diamond centre stage
• Diamond band – stones set along the band for added brilliance around the finger
• Hidden halo – a subtle row of diamonds tucked beneath the centre stone

Lifetime benefits included with every ring

When you buy from us, the relationship does not end at the point of sale. Every ring includes free resizing, polishing, and cleaning for life, plus complimentary engraving. These are standard inclusions with every purchase, not optional extras.

Your ring is also made entirely in the UK, within our Hatton Garden workshop. That means tighter quality control, full transparency over production, and a finished piece built to last well beyond the occasion it marks.

Where they are based and how to contact them

A Star Diamonds Hatton Garden sits at the heart of Hatton Garden, London’s historic diamond district. The workshop and showroom are at 30 Greville Street, London, EC1N 8TB, within easy walking distance of Farringdon and Chancery Lane underground stations.

Finding the showroom

Hatton Garden packs dozens of jewellers into a compact area, so having the exact address before you visit saves time. A Star Diamonds operates from a dedicated workshop, not a shared retail floor, meaning your consultation takes place in a focused environment rather than a busy shop floor.

If you are travelling from outside London, both Farringdon and Chancery Lane connect to major rail and tube lines, making the journey straightforward to plan.

Getting in touch before your visit

You can reach the team through the following channels:

• Phone – for direct conversations about your requirements
• WhatsApp – useful for quick questions or sharing inspiration images before your appointment

Booking a consultation in advance is recommended, as it ensures the right specialists are available to give your brief full attention.

Reaching out before your visit lets you arrive with a clear idea of what you want, which makes the first conversation far more productive.

How the bespoke ring process works

The bespoke process at A Star Diamonds Hatton Garden follows a clear structure so you always know where you stand and what comes next. From your first consultation through to collecting the finished piece, our team guides you through each stage without rushing the decisions that matter most.

Your initial consultation

During your first appointment, a goldsmith or designer sits with you to discuss your vision, budget, and timeline in full. You can bring reference images, describe what you have in mind, or simply start with a preferred metal and stone shape. This conversation shapes every decision that follows, so nothing is too minor to raise at this stage.

Design, approval, and crafting

Once your brief is confirmed, we produce detailed design visuals for your review before any metalwork begins. You sign off explicitly, so nothing moves forward without your clear approval. Our in-house crafting team then builds the ring within the Hatton Garden workshop, keeping every stage under one roof. That means fewer handoffs, tighter quality control, and a direct line back to the people who designed it if you have questions.

Approving the design before production starts means the finished ring reflects exactly what you agreed, with no unexpected changes along the way.

Natural vs lab-grown diamonds and ethical sourcing

At A Star Diamonds Hatton Garden, you choose between natural diamonds and lab-grown diamonds, and both options meet strict ethical standards. Natural diamonds are mined and certified, while lab-grown diamonds are created in controlled environments using the same carbon structure as their mined counterparts.

What makes lab-grown diamonds different

Lab-grown diamonds are physically and chemically identical to natural diamonds. The difference is origin, not quality. They typically cost significantly less than natural diamonds of comparable size and grade, which gives you more flexibility on stone size or cut without stretching your budget.

Your choice between the two often comes down to personal values and priorities rather than any difference in appearance. Both types look identical to the naked eye, and both hold up to the same everyday wear.

How ethical sourcing works

A Star Diamonds stocks only 100% conflict-free lab-grown diamonds and responsibly sourced natural stones. You can ask our gemologists directly about the provenance of any stone you are considering before committing to anything.

Knowing where your stone comes from matters just as much as how it looks, and full transparency is something we offer as standard.

That level of openness means you go into your purchase with complete confidence, not just in the ring itself, but in the values behind it.

How to check reviews and compare Hatton Garden jewellers

When you are researching A Star Diamonds Hatton Garden alongside other options, independent reviews give you the clearest picture. Check platforms like Google Reviews directly, as these are verified and harder to manipulate in bulk compared to testimonials hosted on a jeweller’s own website.

Where to find reliable reviews

Google is the most straightforward starting point. Search the business name and read through recent reviews, paying attention to comments about communication, finished quality, and how any problems were handled. A pattern of positive detail, rather than generic praise, tells you far more than an average star rating alone.

Consistent mentions of the same strengths across multiple reviews, such as clear communication or high craftsmanship, carry more weight than one-off compliments.

What to look for when comparing jewellers

Not every jeweller in Hatton Garden works in the same way. Some sell pre-made stock, others offer partial customisation, and a smaller number, including A Star Diamonds, design and craft entirely in-house. When comparing your options, ask each jeweller directly:

• Whether production happens on-site
• Who designs the piece
• What aftercare is included as standard

Those three questions cut through most of the ambiguity quickly and make it straightforward to compare what you are actually getting for your money.
