Your Precious Memories, Expertly Crafted.

A celebration of a new achievement, a sign of friendship and affection, the promise of a life shared together… Fine jewellery may symbolise many things, but it will always have one true purpose: the crystallisation of a passing moment, so that it may last forever.

At 77 Diamonds, we know that your jewellery is more than a simple object—it is a symbol of profound love. In order to create a jewel that faithfully fits your narrative, we offer a personalised service that enables you to design your item from a single diamond or setting. With showrooms based in the UK and Germany, our team of experts will offer all the advice you need to help find the perfect jewel.

Once you have decided on a design, our master jewellers will then craft your item to your desired specifications. Based in the heart of London’s luxury quarter, Mayfair, they will create a piece that is unique to you, one that you can cherish and pass down through generations.
