Dear Valued Customer
After over a century of operation in the diamond business, IDC has reached the difficult decision to wind down its London operation. This decision has not been taken lightly, and we recognise and want to mitigate the impact of this decision on our customers. Over recent months we have evaluated every path that could preserve the standards you rely on—product quality, continuity of supply, and responsive technical support.
The outcome of that work is a structured transition: effective 16/10/2025, Shannon Abrasives Ltd. will assume responsibility for servicing all IDC customers. We chose Shannon Abrasives because they know IDC’s products and processes intimately, having collaborated for many years, and we share a commitment to precision and reliability.
I will personally be joining Shannon Abrasives, with the initial support of our London team, to ensure your specifications, materials, and delivery schedules continue without interruption.
What’s Changing (and What Isn’t)
Joining forces with Shannon Abrasives
Effective 16/10/2025, Shannon Abrasives will take over servicing all IDC customers. IDC and Shannon have worked together for many years, building a strong, trusted relationship and a deep understanding of each other’s businesses. We’re similar in size, share deep roots in the diamond industry, and have long experience fulfilling the precise requirements of global clients. This makes the decision to join forces the natural next step.
Customer impact
Our priority is that you experience as little change as possible. To that end:
-
IDC’s entire London diamond stock has been transferred to Shannon Abrasives premises in Ireland.
-
The machinery used to manufacture the products you currently buy has also been transferred.
-
Key IDC personnel will support Shannon throughout the transition, and I will be on hand to ensure products continue to be produced exactly as before.
In practical terms, the only visible change to you will be the company name on your invoice. Everything else remains the same:
-
Same materials
-
Same machines
-
Same people still involved in production
