“SEVENTY YEARS OF CELEBRATING THE MOMENTS THAT MATTER MOST.”
EST. 1956 · HATTON GARDEN, LONDON · JEREMY KANZEN & GARY INGRAM
We didn't set out to build a jewellery company. We set out to help people give gifts that would mean something, not just on the day they were given, but years later too.

JEREMY'S STORY
“WHILE OTHER CHILDREN WERE PLAYING FOOTBALL ON A SUNDAY, I WAS IN MY FATHER'S WORKSHOP.”
I spent my weekends surrounded by diamonds, watching craftsmen work, and doing something that would prove more valuable than any qualification: talking to customers.
What I learned very quickly was that people weren't really worried about the technical details. They weren't lying awake thinking about carat weights or clarity grades. They were thinking about the person they loved. They were thinking about a proposal, an anniversary, a birthday, or a special moment.

“IT WAS NEVER ABOUT THE DIAMOND IT WAS ALWAYS ABOUT THE MOMENT IT WAS MEANT TO MARK.”
Jeremy Kanzen, Co-Founder & CEO
A lot of the time, people would come in nervous. My job was simply to listen, ask questions and help them find something that felt right. I loved that part. The thing that stayed with me was seeing what happened afterwards. Customers would return and tell us how the proposal went. They'd come back years later for wedding rings, birthday gifts or christening presents. They'd bring in family members and friends. I realised our purpose wasn't to sell diamonds; it was to help people create memories that last a lifetime.

GARY'S STORY
“I GREW UP IN A SMALL FISHING VILLAGE IN CORNWALL.”
Even from a young age, I had a feeling there was more out there for me. Not necessarily in terms of money, but in terms of opportunities and experiences.
When I moved to London, I ended up working in property. Looking back, it taught me lessons I still use every day. You learn how to deal with people. You learn how to listen. Most importantly, you learn that if you take the time to understand what someone really needs, you can help them make the right decision.
Around the same time, the internet was beginning to change everything.

“JEREMY HAD THE HERITAGE. I HAD THE VISION FOR SCALE.”
Gary Ingram, Co-Founder
I became fascinated by how people searched for information and made decisions online. I taught myself digital marketing, search, content and e-commerce. I spent years learning how trust is built when you've never met the customer face to face. What I had was an understanding of the online world. What I didn't have was the right product. That's where Jeremy came in.
He understood jewellery and customers. I understood how people were beginning to shop online. The more we talked, the more it felt like there was an opportunity to build something together. And what started as a few conversations over dinner eventually became The Diamond Store.
When we launched The Diamond Store, the idea of buying diamond jewellery online was still relatively new. A lot of people thought it wouldn't work. Jewellery is personal. People want to see it, touch it and try it on. We understood the scepticism because we had some of the same concerns ourselves.
One of our first online customers was a lady called Julia. After her order arrived, we called her to make sure everything was as expected. We were still new to online retail and wanted to know how the experience had been.
It showed us that customers didn't need to walk into a showroom to trust us. They needed honest advice, quality jewellery and great service. Whether they're standing in front of you in Hatton Garden or opening a box at their kitchen table, anywhere in the world. That belief still guides us today.
Nearly three quarters of a million customers later, we're still focused on the same thing we were back then: helping people celebrate life's most important moments with jewellery they'll love for years to come.
A piece of jewellery often marks a moment you'll never forget. A proposal. An anniversary. The birth of a child. A milestone you've worked hard to reach. That's why we take the time to understand what you're looking for and who you're buying for. The jewellery matters, but so does the story behind it.
Buying jewellery is a significant purchase, and for many people it's something they only do a handful of times in their lives. Our team is here to help you navigate the options, answer questions and find the right piece. Whether you're choosing an engagement ring, a birthday gift or a personal treat, we'll help you shop with confidence.
For over 70 years, we've built relationships with some of the finest jewellery workshops and diamond suppliers in Hatton Garden and beyond.
By sourcing directly, we're able to offer exceptional quality, a wider choice and competitive prices without unnecessary markups. Every piece is carefully inspected before it reaches you.
The best jewellery stays with you. An engagement ring becomes an heirloom. That's why we focus on quality craftsmanship, durable materials and timeless design. We create jewellery to be worn, loved and passed on.
Chemically and visually identical to mined diamonds, lab-grown diamonds offer exceptional beauty with a lower environmental impact. Today, they make up more than half of our collection.
Across a growing proportion of our range, we use recycled gold, silver and platinum, helping to reduce the demand for newly mined materials.
All our natural diamonds are conflict-free and sourced in compliance with the Kimberley Process. Every piece is independently hallmarked as a guarantee of quality and authenticity.
Recognised for our commitment to environmental and social responsibility.
Whether you're celebrating an engagement, a birthday, an anniversary or simply treating yourself, we're here to help you find something you’ll love for years to come.
