Quoins – Callow Sandstone

These warm red sandstone quoins are cut from masonry quality block stone at our Callow Quarry on the Herefordshire/Monmouthshire border. Callow natural sandstone quoins can be cropped and finished to any size and specification. Quoins and cornerstones are ideal as both architectural and landscaping features.


The red sandstone we cut here at out Callow Quarry is masonry quality block stone. We use it to produce a wide range of building and walling materials, depending on your preferred building technique and the finish you are looking to achieve.

For random stone walling we produce a random cropped building stone which is also available in a tumbled finish. For coursed stone walling we produce a coursed tumbled stone and a coursed pitched-face stone. We also offer a product unique to Black Mountain Quarries with our Vintage Building Stone, also available with a tumbled finish.

Callow quoins are normally provided with 2 split faces and can be cropped or sawn to your required dimensions.  They can be provided in specific heights and lengths, or random dimensions to match our random building stone.  As this sandstone is from our own quarry we can be very versatile with producing products to precise dimensions and requirements of our customers; please contact the office with your requirements and we will be able to calculate prices and lead times.

We can create a range of bespoke items from our Callow Quarry, made to your required dimensions such as steps, wall coping, pier caps, once and twice weathered coping etc to complete your walling project; please ring or email with details.

While we have done our utmost to ensure the stone colours displayed in our website are accurate, they are to be used as a guideline only. As stone is a natural product colours will vary from piece to piece and shapes of the stone will vary depending where in the quarry the stone has been dug. Please bear this in mind when ordering colour samples as there will be variation and this gives the stone its unique character.
