About Carriage Diamonds

We specialise in fine bespoke jewellery, as you've gathered, including diamond engagement rings, eternity rings and wedding rings, in platinum and 18ct gold. Here, we also offer a beautiful range of classic and modern ladies' pieces. The majority of our diamonds are independently certified by IGI or GIA. We can source any quality diamond no matter what cut, colour and carat. So, have a browse and then feel free to come straight to me with any questions. 

That's actually me on the right. I've been at a jeweller's bench like that one for a very large part of my life. Roughly since I was about sixteen or so. My team and I really do know how to create beautiful pieces of jewellery. Very importantly, ones that stand the test of time ie. they are of very high quality. As already explained, I can source some of the best-certified materials out there but essentially I know just what it takes to put together the perfect piece. You will see this the day you wear yours.
That is effectively what we are about - stunning pieces, whether simple or complex, made by people who have been creating such things and working in our trade for most of their lives.

We are in the heart of the UK's diamond and jewellery trading district so when you come to meet me at my workshop in Hatton Garden, you will have a complete experience. From the buzzing atmosphere outside to the relaxed yet highly attentive and professional one in my workshop.

That's enough about us, come and meet us.

Customer feedback

Michael was very patient and explained everything I needed to know. He never once gave a sales pitch, instead letting the products speak for themselves.
