Delabole Slate is the centuries-old trade name for products of the Delabole Slate Quarry in Cornwall, probably the oldest working slate quarry in the world and the only source of Delabole Slate.

Our unique material is internationally renowned for its superb durability and aesthetic appeal as well as for its historical importance, being used in many prestigious and ancient buildings across Great Britain and the Commonwealth.

Although over 10 million tonnes has already been mined from the quarry in the last 1000 years, we still have mineral reserves for another millennium.

We are specialist producers of bespoke and traditional slate products for the building and home improvement sectors, offering a friendly service direct to both public and trade.

We also run tours of our ancient quarry – so why not visit the home of the best slate in the world!

We look forward to hearing from you...
