Vores løfter

At 77 Diamonds, every jewel we create is shaped to fit a moment. Your moment. Whether you are planning to propose, organising a wedding, or simply wish to celebrate a special occasion, we make the following promises to you.

Fine Craftsmanship

Our jewellery makers are masters in their field, deeply passionate about their craft and perfectionists till the very last polish. Some of our jewellers have more than 30 years of experience in the trade, and each bring their own unique vision to their work. Our in-house team of designers conceptualise pieces that will be loved and worn for a lifetime, and create collections that are testaments to boundless creativity and talent. All our pieces are handcrafted and made-to-order in the centre of Mayfair, London’s famous luxury quarter, and we are proud to be part of this heritage and tradition.

Quality With Affordability

Since crafting our very first piece in 2005, we knew we wanted fine jewellery to be in everybody’s reach. Whether an engagement ring or a jewellery piece, our platform will always guarantee affordable prices without compromising on quality, whatever your price range.

How do we achieve this? We have refined our process through the years and are now able to source all diamonds and gemstones directly from manufacturers and polishers. By cutting out the middleman, our online platform moves away from traditional retail to offer gems at a fraction of their price. This is why you’ll notice some of our diamonds have very recent grading reports.

Complimentary Ring Resize

We know how difficult getting the right ring size can be, especially when you are planning a surprise proposal. For your peace of mind, we offer a complimentary ring resize within 30 days after you receive your item. Simply contact our team and we’ll provide all necessary information on how to return your item. Please bear in mind that not all rings can be resized due to their complexity and some will need to be exchanged.

Unparalleled Guidance and Support

Your jewellery is important. It’s a reflection of a shared story, a loving moment set in stone for a lifetime. It’s your perfection. As expert jewellers, our aim is not only to help find the ideal jewel, it’s also to guide you through some of the most meaningful moments of your life. Whatever the occasion and whatever your requirements, our team is always available to assist you and answer any question.

To help with your decision, you can meet with one of our experts at our luxury showrooms or opt for a tailored phone consultation. We will review your preferences and price range, and provide you with a selection of designs and centre stones to choose from.

Independent Grading Reports

Purchasing a diamond or a gemstone for the very first time can seem daunting. To help you make the most informed decision, each stone in our catalogue comes with its own grading report. We only provide independently graded gems, to ensure the quality you are purchasing matches as closely as possible the information provided. Even though we could, we refuse to self-certificate our products and will always keep you informed of the standards and accuracy level of certain laboratories and institutes.

Lifetime Warranty

With any purchase at 77 Diamonds, you receive a lifetime warranty should there be any manufacturing issues with your item. Although manufacturing defaults are extremely rare, you are entitled to all necessary repairs free of charge if this ever happens.

To benefit from this warranty, the default must be identified by our production team and cannot be the result of mishandling or normal wear and tear. For further information, please visit our Terms and Conditions.

Responsible Sourcing

Fine jewellery is not only about the finished product, it’s also about the story behind it. A diamond or a gemstone travels a long distance before it is finally placed in a jewel, and it is our responsibility as jewellery makers to ensure it comes from reputable sources.

Since our humble beginnings, upholding standards of ethics and integrity have been an important part of our identity. All our diamonds fall under the Kimberley Process Certification Scheme, meaning they have not funded any armed conflict. That’s good, but it is nowhere near enough. To further improve our sourcing policy, we are following industry standards for responsible sourcing of gemstones and precious metals and are closely working with our suppliers to ensure human, social and environmental norms are always respected.
