Celsteel Diamond


The Diamond Wholesaler You Can Trust



Celsteel is a third generation company that was established in 1952 and has been run as a family concern ever since. We have traded all over the globe, and are now pleased to say that there are very few countries in the world with whom we have not traded, either as a supplier or a customer. We try to offer all our customers a personal touch that only a family company like ours can give.

We pride ourselves on being able to supply our customers with the goods that they need when they need them.

No matter what the demand in diamonds and how impossible other companies find it to supply, our worldwide network of contacts will find what our customers need. We would like to invite you to contact us and become part of this network, as we believe our businesses can only go forward if we all have the right mixture of good customers and good suppliers.

Celsteel is a founder member of the International Coloured Gemstones Association, a member of the National Association of Jewellers and a member of the Gemmological Association of Great Britain. We only sell non-conflict diamonds – covered by the Kimberley Process.
