My Fiance designed my engagement ring with E.C.One and had this experience; "Gentlemen (and ladies), if you want to go the extra mile on your engagement ring and pocket yourself some infinitely redeemable brownie points, then look no further. You have the freedom to design your engagement ring at EC1. They can and will hold your hand, until you are ready to pick up that heavy little jewellery box of emotions. I gave them a tight brief, explaining the type of metal, jewel, shape, setting and personally of the ring I wanted. They gave me technical advice, options on my criteria, a comprehensive explaination of the 4 c’s and plenty of opportunity to review. You don’t have to have a concrete vision, as experts are on hand to decifer your rambling mind. You can take friends in at any point and they are more often than not amenable to you dropping in at a moments notice. Time wasn’t a factor for me but obviously this takes longer than picking a ring off the shelf. From start to finish it took 3 months, but this included some indecisiveness on my part. I would suggest two months to be on the safe side or three months if you can’t make your mind up. You can ask them to make up a silver model which costs £250. Once I went ahead with the design, that sum was taken off of the final price. E.C.ONE did not give a specific amount regarding their margin, but I did come away feeling like I got a great deal and more than a off-the shelf ring. My fiancé loved it and has told the story how the ring was made so many times now that she has run out of friends and family to tell. I have since told her that strangers aren’t and never will be her target audience. E.C.ONE made us something really quite special."

Wonderful service! Repairing and cleaning a chain (not bought there) for free! Lovely store and lovely people. Highly recommended.

Jos and the team were fantastic! Super relaxed friendly experience compared to other shops trying to force a sale. Engagement ring was beautifully made and can't wait to go back for the wedding bands.

Brilliant business. Driven owners who love what they do - happy staff. Quality/gorgeous jewellery sourced ethically. Nothing to fault.

Jos and the team at EC One helped us through our journey of building our engagement ring. They were really helpful with designs and answering the questions we had. They provided us with the background to the stones we weren't able to get at other jewelers. Will be using them again in the future.

Really amazing service from all of the team at EC One, particularly Jo, who was superb from first contact! Absolutely over the moon with the final quality of a beautiful engagement ring and would recommend time and again!

Fantastic service, great staff and very transparent pricing. Thoroughly recommend.

I bought the engagement ring for my fiancee at EC One and was delighted with the service from the team there. They are highly knowledgable, attentive and friendly. Their commitment to ethical sourcing and sustainability is fantastic without any compromise on quality. We will definitely return for our wedding bands and would highly recommend them for anyone looking to make a jewellery purchase.

A lovely company and a stunning engagement ring! We couldn't be happier. Thank you so so much to the team.

I lost one the hoops of a pair of drop earrings I bought from EC One very shortly after my purchase, but thankfully still had the pendant part of it. The team very kindly sourced a replacement and sent it to me - excellent service, thankyou.

I have just received my wedding and engagement rings back from EC One, both repaired, and both look fabulous. All communication and transport of the rings was done during lockdown 3.0 - so email and royal mail. Their communication was excellent, the new jewel is just what I had in mind and I'm really pleased. I would definitely recommend them.

Amazing customer service! The team is really personal and genuinely have the customers interests at heart. I had a bespoke engagement ring made with EC One and Jo was so helpful in getting my vision down on paper and then into reality. I’m looking forward to getting my wedding bands done with Jo and the rest of the team!

This is my favourite jewellery store in London. Everything I wear on a daily basis has come from here including a bespoke ring they made for me 20 years ago using my Mum's engagement stone. It's a beautifully curated collection and they are committed to championing new talent.

A totally and utterly joyful experience. If Carlsberg made jewellery...

So glad I've discovered EC One. Groovy neighborhood, amazing jewellery, first rate service. Def recommend.

A wonderful business based on a high quality service, looking after everyone involved and giving excellent value for money. Great customer care, a genuine concern for the environment from a contemporary and cohesive team that lead by exemplary practice.

EC One is the ONLY place I buy jewellery. My family and I have been shopping there for years. The customer service and client attention from Jos and Alison and the team is first-class. The workmanship is exceptional for these forever pieces.

My pectoral cross from EC One was beautifully designed and crafted, with outstanding service in a restricted time frame. Very highly recommended.

I had come across EC One via Instagram and instantly fell in love with all of their beautiful pieces. My fiancé booked us in for a surprise appointment to design my engagement ring. It was the best experience I could have wished for. Jo and Elise were absolutely amazing. They were both so friendly and welcoming and made us feel completely at ease during the whole process. We were able to try on so many different styles of rings until we found the one we liked the most. They then sourced various different stones in a variety of colours for us to choose from. What we have ended up with is the most stunning sapphire and diamond engagement ring and wedding bands to match. We are genuinely so grateful for all of Jo and Elise's help and guidance. We also wanted to thank the incredibly talented goldsmiths who created such beautiful pieces for us. We will be forever grateful.

Brilliant service and produced a beautiful ring. Would thoroughly recommend for anyone planning to pop the question!

We had a wonderful experience with EC One. They made and engraved our wedding bands which are so beautiful, made size adjustments as required and even fixed an issue with my engagement ring (that was made elsewhere) at very shot notice when I realised there was a problem with it 3 days before our wedding! Lovely people and beautiful designs. Highly recommended!

First, it is a B Corp which for those not aware is a prestigious certification for companies who care about people and planet. Second, my personal experience was fantastic. My ring was initially slightly too big so I brought it back in and they resized it within 10 minutes. They even gave me a plaster for a blister on my foot! Very happy customer

I've never had a piece of bespoke jewellery commissioned before so wasn't sure exactly what to expect, but from beginning to end the process with EC One was pretty much everything I was imagining and hoping for. The initial consultation was super helpful with getting high level ideas on what sort of designs might be to my partner's liking - she'd mentioned she was quite drawn to art deco styles. The next meeting shortly after to choose from a set of teal sapphires EC One had obtained for the engagement ring made me feel very involved in the process. Then the CAD drawings were great for visualising the end result as well. And all the EC One staff were so friendly throughout and obviously super knowledgeable about jewellery. My partner loved the ring in the end too. All in all brillant. Couldn't recommend this place enough!

Superb service! We went to EC One for my bespoke engagement and wedding band. Everyone was friendly and helpful. 10/10 recommend if you’re looking for an independent jeweler.

The team is absolutely lovely, sure. But more than that they are very skilled craftsman. I came in to request a re-sizing of my pinky ring, barely able to articulate what it was that needed to be done : they very intuitively understood and perfectly executed what I merely imagined. My delicate and precious jewel came back from their workshop feeling even more mine & familiar than ever. I am beyond happy by the precision and delicacy with which they handled this job. Thank you ever so much !

I visited several jewellers before deciding to go with EC One for an engagement ring, as all your staff were so friendly and inviting. I felt very comfortable asking all the basic questions I had as a complete novice in the world of jewellery. Jo was especially helpful in guiding me to find a design that fit my very confusing brief, without ever being too directive. To top it off the care and flexibility around resizing the ring afterwards was brilliant.

I can't put into words how much we love our mother-daughter rings or how incredible EC One has been through the whole bespoke process. The care and craft EC One showed in making our emerald rings really touched me. They are such genuine, talented and kind people who care as much as you do about making your very own beautiful and meaningful piece of jewellery. Will treasure our rings and the special experience they made for us for a very long time. Thank you so much to Jo and everyone at EC One. Cannot recommend or praise them more highly.

We had a fantastic experience designing two engagement rings with Jos at EC One. If you're looking for somewhere for sustainable, ethically sourced, thoughtfully crafted jewellery, this is it. Jos was kind, helpful, and also great fun! We really enjoyed ourselves every time we met with him. Over a number of different visits he helped us hone in on what we really wanted and we never felt rushed or pressured to make a decision. We are thrilled with the end product. As a queer couple we also really appreciated the inclusive nature of EC One's business. We can't recommend them enough!

So glad I went with EC One for an engagement ring. A very enjoyable a friendly service from start to finish. A beautiful ring and a thrilled fiancé. Highly recommended.

I couldn't recommend EC One more to anyone looking for a beautiful bespoke engagement ring. It can be a very daunting process choosing a jeweller, finding a diamond and designing the ring, but Jo and the team were absolutely fantastic and made me feel in safe hands throughout the whole process. Every time I wanted to make a change, or ask to see a new stone, everyone was so kind and understanding, and nothing was too much to ask. Everyone was so patient in explaining all about the diamonds and the process, and it was really nice to know that the company has such a focus on ethical and sustainable jewellery. The finished ring is absolutely perfect and I was completely blown away for the big reveal. My fiancée loves it and we can't wait to come back to design the bands together! Thank you to everyone at EC One for doing such a fantastic job!

Jo was fantastic. Put me and my now fiance completely at ease and we couldn’t be more happy with the ring. I would recommend EC One in a heartbeat.

You're in for a real treat when you drop into Econe. Amazing boutique jewellery shop with incredible service, on-site artisan craftspeople and BCorp status to boot!

Jo and the team at EC One made a beautiful bespoke engagement ring for myself and my partner. The engagement proposal was due to be something of a surprise, though I had been given a good idea of what my partner wanted! From the start Jo helped me to navigate the process from initial consultation via email, a visit to decide on diamonds and further details, right through to the finished article. I let her know my budget and she gave me a number of options to suit. Rings, diamonds and women’s jewellery is not an area of expertise of mine, but Jo did well to help me along the way! The team also sourced a lab grown diamond for our ring, which was a pre-requisite for me. The shop is lovely, and it makes the ring much more special for myself and my partner knowing that it is a bespoke ring from a boutique London jeweller. If you are thinking about buying an engagement ring I would absolutely recommend EC One. And if you aren’t sure about going bespoke, I would definitely also recommend doing so with this jeweller. We will be back for our wedding bands soon. Thanks again to Jo and the team. Alicia & Tom

My fiance and I had been shopping around engagement rings both online and offline for about month before discovering EC One. We chose them to design my ring, and are really delighted with the result. One of our requirements was for an unusual, ethically sourced teal-coloured centre sapphire, and they were great about sourcing different stones for us to look at and answering our many questions. They also sourced lab-grown diamonds for the ring for us, something that was unusual compared to other high-street jewellers. A good choice if you want to design your own ring/jewellery as ethically as possible.

Fantastic experience, fantastic service. Jo and the team expertly guided me through the process of buying a beautiful, bespoke engagement ring and helped me get the result I was looking for! Would highly recommend.

Relaxed, friendly staff who can't do enough for you. All smiles, plenty of time to look around, no pressure to buy but many, many beautiful things to buy if you can. A brilliant range of prices from affordable to once-in-a-lifetime special. A uniquely wonderful. shop.

What a great experience!!! Very friendly and helpful throughout the process. Thanks for Jos, Jo and the rest of the team I felt really comfortable and confident since the very beginning that the result will be great. Thank you guys for understanding exactly what I wanted, and design and create a engagement ring as I dreamed for my partner. She really loved it!

Elise and the team at EC One helped me design the perfect engagement ring! They helped me throughout the process, from sketching an initial design, picking stones, produce a high quality CAD rendering and delivering the final ring. Whenever I came in to discuss the design or make a decision, they were extremely helpful, patient and supportive. I couldn't have been happier with the process and how the ring came out. After the ring was delivered, they made sure that the fit was perfect for my fiancée - adjusting the ring several times. They are lovely independent business - I highly recommend them!

EC One is a wonderful independent jewellery boutique located in Exmouth Market. My wife and I had the pleasure of meeting Jos and the team who helped design my wife's wedding band. Since then, I have always felt so welcome when I have returned to find a special, unique jewellery gift for my wife. The team have helped me find some very special pieces which my wife treasures. I would highly recommend visiting if you are looking for a thoughtful gift for a loved one.

You will be put at ease immediately by the delightful staff as soon as you enter this cornucopia of elegant design. There are so many beautiful pieces to choose from - something for everyone's budget. And best of all - ask them about supply chains: this is ethical jewellery on steroids. Just brilliant.

Amazing, ethically made and sustainable jewellery! I was surprised with a astonishing engagement ring and I could not be more happy!

I had an engagement ring custom designed and made by EC One - what could have been a daunting experience was made very easy and fun by the fantastic and talented staff. The end product was a beautiful and unique ring which my fiancé was delighted with.

Jos and his team were fantastic! They helped us design a bespoke piece of jewellery - their guidance throughout the process was always so helpful and we love the finished item.

Jos and team did an absolutely incredible job designing my engagement ring. Jos completely understood my vision and made it come to life in the most beautiful unique piece. It is stunning! Can't wait to design the wedding band with them next!

My partner and I have been buying pieces from EC One for over 15 years, so they were a natural choice for us when we wanted to have an engagement ring made, despite the fact we now live in Marseille. We love the boutique, their ethical approach, the location, everything basically. The whole experience with EC One was great from start to finish. We were encouraged by Jos to come with ideas if possible, so we visited the permanent jewellery exhibition at the V&A to get inspired. We worked with him and his team to develop our initial ideas and the final result was unique and perfect. The ring design was simple but unusual, so they produced CAD drawings and then a 3D prototype for my partner to try and to see how the stones would be set. When we came to pick up the ring there was a tiny size adjustment needed, which they did on the spot. Great team, beautiful ring, happy couple!

Fantastic experience courtesy of Jo, who helped us find a beautiful engagement ring - it's perfect. Thank you!

This is the place to buy all your jewellery -- brilliant staff, ethical trade, remarkable customer care and breathtaking designs. Seriously: check it out......

EC One is a brilliantly edited collection of jewellery and I have never given a present from here that has caused anything other than delight. But the thing I value most is that they are trustworthy and their pricing is fair. This is particularly important if you are lucky enough to buy fine jewellery here - it is so easy to be ripped off. At EC One, you can relax. Special call out for their workshop which makes beautiful pieces but always with a twist. EC One nails chic style everytime.

Jos and Alison are wonderful people who care for their dedicated and friendly staff. They also have a real vision for making their business sustainable and slavery-free. I wouldn't go anywhere else for something sparkly! Beautifully created and curated jewels and the kind of personal service that money can't buy.

Beautiful shop with staff who have perfected the art of helpful, but not pressuring, assistance making for a lovely jewellery buying experience. Would highly recommend Jos for fabulous bespoke pieces.

Friendly, knowledgeable and you will be my 'go to' jeweller from now on. Thanks for a lovely evening

Excellent in every way - knowledgeable, enabled me to make informed and satisfying decisions. That way I gained the most beautiful ring, a real triumph of turning a vision into an even better reality. Staff are infinitely patient and work with you to create what you want.

We had our Wedding rings made here, the team were fantastically friendly and gave great advice. Some places we’d visited had been a bit sniffy about recycling gold from a family ring, but at EC One they didn’t bat an eyelid.

We had our wedding rings and my engagement ring made by EC One - they were just brilliant. I wanted something a little different / less traditional which was surprisingly hard to find in London! EC One made us feel so welcome and didn’t make me feel like I was strange or awkward for wanting the non traditional. They were so helpful and were excited to source and make something different. It was a very personal and fun experience having our rings made. Jo was great at helping to get the designs just right, I had a silver model of my wedding ring made to make sure we were happy with the design and they sent photos of my ring being made. Great to support an independent business, would definitely recommend!

I recently had an eternity made to complement my existing Niessing rings. Fabulous service from knowledgeable and friendly staff. Jo made the whole experience a pleasure! Would highly recommend EC One

We were so impressed by the experience of choosing an engagement ring that we returned to buy the wedding rings as well! EC One was extremely knowledgeable and helpful during the whole process and most importantly gave us all the time we needed to make those important decisions. They made it fun! Gavin & Cristina

When recently looking for an engagement ring, I'd researched online and shopped around without any luck, before walking into EC One. I was a little unsure about the process and from the very beginning the team were incredibly helpful, patient and genuine in helping me to make the right choice. There was no pressure in any of our conversations, which meant I was free to take my time and compare a selection of stones they had in store to others they were able to order in. Even after inevitably getting the size wrong, the process of resizing couldn't have been simpler. A great service.

Really friendly and accommodating. EC1 certainly helped me understand all the options for a tricky purchase. They have different and far better designs than the standard offerings in Hatton Gardens (and they're not salesy!) Highly recommend

I visited the store to consider making a new piece of jewellery from three rings. I was widowed and I still wanted to enjoy my engagement, wedding and eternity ring but needed them to look and feel different. Jo at EC One was so sensitive and caring. She patiently worked with me (and the team behind the scenes) to create a new piece which I am thrilled with. The team at EC One are so talented. I have had many comments about my ring, now my past moves forward with me in a new sparkly way.
