Where to buy an ethical engagement ring in London

London is one of the best cities in the world to buy a responsibly sourced engagement ring. Search for the most well-known names in the space today and you’ll likely land on Kimaï, Taylor & Hart or Blackacre; large brands that have worked hard to bring transparency and traceability into the mainstream conversation.

Hatton Garden, London’s historic jewellery quarter, is home to several independent design and craft studios that have spent years building the same kind of genuinely transparent supply chains, quietly and without the marketing budgets of their bigger counterparts. This expert insiders’ guide introduces a handful of them too, alongside a framework for evaluating any responsible jeweller you encounter whilst exploring your options in our vibrant and forward-thinking capital city.

How to research a responsibly sourced engagement ring before you buy

At Lebrusan Studio, we’re not alone in our conviction that it’s possible to enjoy Mother Nature’s gifts of precious materials in ways that are considerate and restorative. From Fairmined Ecological Gold mined without the use of any mercury or cyanide, to artisanal Ocean Diamonds extracted carefully from the Namibian seabed by skilful career divers, and visionary diamond dealers in Hatton Garden repurposing beautiful antique diamonds for jewellers like us to reclaim - when it comes to investing in an engagement ring whose story you can feel truly proud to tell, the possibilities are abundant.

It is worth noting early on that there is an important difference between jewellery that offers easy reassurance and jewellery whose story is more textured. Some brands position themselves around the idea of “guilt-free” buying; a single tidy answer designed to put your mind at rest. Recycled gold and lab-grown diamonds, for example, are used widely Led by contemporary artist and ethical pioneer Arabel Lebrusan, Lebrusan Studio has never conformed to the notion that precious materials are quite so simple. Responsible sourcing is layered, involving considered trade-offs between supporting mining communities and reducing carbon footprint; between celebrating a precious material’s natural history and remaining mindful of our demand for extractive activities. With honesty and nuance, we would much prefer to walk you through the complexity of these issues – not offer you a shortcut around them. A piece of jewellery as significant as an engagement ring deserves to be chosen with compassion and empowerment; knowledge of its story is what enables you to connect with it deeply and meaningfully.

If you’re just embarking on your search for a responsible engagement ring, this wealth of opportunity might feel a little overwhelming. That’s why it’s important to spend a little time researching and comparing the responsible precious materials available to you, and the environmental, social and economic complexities that have given rise to them in the first place. In order to build a framework that aligns with your moral compass, equipping yourself with knowledge is the best place to start. You might find our informative Ethics pages useful at this stage.

What questions should you ask an ethical jeweller?

As a leading design studio in the ethical jewellery space ourselves, we know it’s easy to be honest. Anyone who is truly committed to transparency, traceability, environmental restoration and positive socioeconomic impact will be proud to talk about the tangible, proactive steps they are taking towards the better future they see in their mind’s eye.

1.     WHAT: What materials make up this piece of jewellery?  Not every jeweller works from the same moral framework, and so there is no full scope of responsible materials offered across the board as standard. What your jeweller should offer, however, is a comprehensive explanation of the options they work with and why exactly they have chosen to work with them. When you truly understand the impact of each option available to you, you are in a position to measure and compare how each aligns with your personal values. We at Lebrusan Studio, for example, have chosen to tread the balance between our society’s ‘Social Foundation’ and ‘Ecological Ceiling,’ committing to precious materials that both actively support artisanal mining communities (Fairmined Ecological Gold and traceable Ocean Diamonds) AND precious materials that are gentle in carbon footprint (recycled gold and platinum, reclaimed coloured gemstones and vintage old cut diamonds). For combined positive impact, we have recently launched our Recycled+ Metals, enabling you to pair your environmentally sustainable recycled gold or platinum with Fairmined Credits which directly support the livelihoods and communities of artisanal miners. How these materials are combined within an engagement ring is entirely your decision, but we’re here to advise you honestly on the stories they tell and how they contribute to meaningful change.

2.     WHO: Who made this piece of jewellery?  Where in the world were the metals and gemstones mined, and under what conditions? Who was involved in mining and processing the precious materials, and later in crafting your special piece of jewellery? Can we be sure they were paid fairly and treated justly by their employer? Though recycled metals and reclaimed gemstones are tricky to trace, third party certification, transparent supply chains and meaningful partnerships elsewhere in our jewellery supply chain help us to tell the stories of the human beings behind our jewellery.

3.     HOW: How were the mining and manufacturing processes respectful of Mother Earth?  Ecological efforts include regeneration of land, protection of waterways, correct waste management and the recycling of materials already above ground. If you can find a jeweller who has taken the time to incorporate this awareness into their supply chains, you’ve found a jeweller who truly cares.

4.     PROOF?  No claim of responsible sourcing can be taken at face value; substance is crucial. Whether a special hallmark to prove Fairmined provenance, an Ocean Diamond certificate of origin with a unique identification number, or paperwork corroborating a gemstone supplier’s commitment to reclaimed provenance, proof is easier to provide than you might think. If your jeweller cannot support what they are describing with tangible evidence, there may be some questions unanswered.

LEBRUSAN STUDIO • The London Diamond Bourse, Hatton Garden

Of course, no ‘hotlist’ is truly unbiased. It’s only right that we sing our own song of praise!

Behind our purposeful, detail-orientated engagement rings is Arabel Lebrusan: leading visual artist, award-winning jewellery designer and key founder of the ethical jewellery movement. As a trained gemmologist with over two decades of experience in jewellery design and a long list of accolades under her belt (including two times National Association of Jewellers’ Jewellery Designer of the Year), Arabel is a multifaceted artist, drawing from a number of cultural and historical inspirations to create timeless heirloom jewels. Our collections of symbolic commitment rings are characterised by tonal gemstones, intricate hand engravings and considered material choices made just as much for their history and purpose as their aesthetic beauty.

As one of the world’s first ever Fairtrade Gold licensees, Arabel is proud to offer a variety of responsible materials chosen carefully to align with our ‘Doughnut Economics’ framework, which concerns itself simultaneously with tending to our Environmental Ceiling and our society’s Social Foundation. This offering includes Fairmined Ecological Gold, Recycled+ Gold paired with Fairmined Credits, reclaimed old cut diamonds and artisanal Ocean Diamonds. We are proud members of the Created in the UK scheme, with all of our engagement rings crafted skilfully in London’s historic Hatton Garden to minimise manufacturing mileage and champion local cultural heritage.

THE VINTAGE RING COMPANY • The London Diamond Bourse, Hatton Garden

When our founder - jewellery pioneer Arabel Lebrusan - and jewellery journalist Claire Roberts first met over coffee in London, it didn’t take long for the conversation to turn to the past. Both share a deep-rooted respect for antique and vintage jewels, their stories, their craftsmanship and their resistance to the disposable. Claire and Arabel’s chat quickly evolved into a bigger question. Why is buying vintage engagement rings still so confusing? Where do you go if you want something beautiful, affordable and authentic? Why are so many of these rings listed with little to no context, when what makes them special is their history?

Claire and Arabel’s argument is that choosing a vintage engagement ring is one of the most sustainable decisions you’ll ever make; celebrating craft heritage and the precious materials already above-ground, avoiding demand for further mining or production in the process. On a mission to bring more joy and ease to the process of reclaiming a pre-loved piece of jewellery, Claire and Arabel founded The Vintage Ring Co. in 2018. Together, they present a curated collection of antique and vintage engagement rings and wedding bands, hand-picked with care and knowledge about what makes a piece of jewellery truly special. Every ring is independently assessed by the Goldsmiths’ Company, lovingly restored where needed by expert craftspeople in London’s Hatton Garden, thoroughly cleaned and polished, delivered with a certificate of authenticity, and ready to propose with.

TAYLOR & HART • 69 MONMOUTH STREET, LONDON, WC2H 9DG | 40 GRACECHURCH STREET, LONDON, EC3V 0BT

Founded in 2013 by Nikolay Piriankov and Shane Hunt, Taylor & Hart began with a simple frustration. Piriankov could not find a jeweller willing to let him design his own proposal ring from scratch. The company they went on to build has since grown into one of the most recognised names in bespoke engagement rings, with showrooms in Covent Garden and the City (as well as NYC) and a design team working with clients across the world.

Every Taylor & Hart ring is made to order rather than pulled from existing stock, with clients paired directly with a design consultant who works through sketches and 3D renders before anything is cast. The studio uses EverLedger to make diamond provenance traceable and offers Fairtrade Gold and recycled gold and platinum alongside its natural and lab-grown stone options, putting material choice firmly in the client's hands rather than presenting a single default.

Taylor & Hart's scale sets it apart from the other independent studios on this list, giving it the resources to run a high volume, design-led service across two showrooms and a large international client base - though the bespoke process and the questions worth asking of it remain exactly the same.

BLACKACRE • 9 WARWICK COURT, LONDON, WC1R 5DJ

Blackacre was founded in 2017 by Samuel Stirrat, a self-taught jeweller and gemmologist whose fascination with gemstones began with a childhood collection of pebbles and semi-precious stones. Working from an atelier near Chancery Lane, the studio has built its reputation almost entirely on bespoke engagement rings and limited edition, stone-led designs, taking on external investment from no one.

What distinguishes Blackacre is the depth of its sourcing story. Rather than working from a supplier list, the team travels to source gemstones directly, filming expeditions to Sri Lanka and Colombia among others and working with the communities who find them. Every piece is crafted from recycled gold or platinum, and in 2024 Blackacre became the first UK luxury jeweller to achieve B Corp certification, scoring 99.3 out of 100 on the assessment, one of the highest scores recorded by any jeweller worldwide.
