IDC has been distributing industrial diamond to toolmakers around the world for over 100 years.


Consistency of quality - We produce our range of industrial diamonds by being very selective in 

the raw material that we use to manufacture our end products. This means that the quality we deliver is consistent time and time again. IDC has a complete range of testing and sorting equipment which allows us to provide our customers with a bespoke service to match their special needs.


IDC is a major stock holder of all types of industrial products both natural and synthetic. This gives our customers comfort that their requirements will be delivered on time, mostly next day. No order is too big or too small



By being major stock holders we are able to obtain bulk purchasing discounts which we readily pass on to our customers.

IDC is a family owned business that can trace its history back to 1890 when it was called Lunzers Limited.  Our late Managing Director, Jack Lunzer, was the driving force of the company and his experience and knowledge of the industry Is continued under the Directorship of Simon Taylor, who has been with IDC since the early 1980’s.

IDC has always been located in the Hatton Garden area and since 1973 has been situated in its own building at 86 Hatton Garden in the center of the diamond district.
