About us

The Diamond Ring Company was created with a vision: to fill a gap in the market for...

  • high quality certificated diamonds
  • set in exquisite jewellery
  • at unrivalled prices
  • with the quality uncompromised

OVer 40 years of experience

Our showrooms are located in the heart of the UK’s diamond trade, in the impressive London Diamond Centre Hatton Garden. Our expertise of over 40 years experience is essential in ensuring our jewellery is fit for a queen (or king) – quite simply, it doesn’t leave our hands unless it is faultless.

Our stock incorporating 10,000+ loose diamonds are all independently certificated by the World’s most renowned and stringent grading institutes including GIA and IGI. Our diamond stock is constantly updated to ensure the prices we offer are the best value in the market place.

We understand the frustration of buying something and then discovering it’s ‘hidden costs’. Therefore we offer a transparent pricing policy, what you see is what you pay. We also offer free UK delivery on any item so no extra costs will be added when you suddenly hit the checkout!

Michael started working in Hatton Garden over 25 years creating a career at the bench which lead to him creating his own workshop serving the trade. Michael has been making beautiful diamond jewellery and from his experience, he can confirm first hand that a diamond is a girl’s best friend.

“We felt that together, our years of experience, enviable diamond knowledge and long standing relation with suppliers, we could create a site that not only provides a superior product, but also offers a seemless buying experience with the highest level of satisfaction.”
