Hamstone is a honey-coloured building stone from Ham Hill, Somerset, England. It is a well-cemented medium to coarse grained limestone characterised by marked bedding planes of clay inclusions and less well-cemented material which weather differentially to give exposed blocks a characteristic furrowed appearance. In origin, Hamstone is a Jurassic limestone from the Toarcian, or Upper Lias, stage.[1]
