Our English limestone fireplaces are made of limestone from the Jurassic geological period. The Bath Stone is mellow, open grained and light in colour with a slightly rough texture. The contrasting Cotswold stone is typically the North Cotswold area being of slightly coarser texture, darker and warmer in colour. The naturally occurring fossils and even some small crystal forms are part of the stones natural beauty and should not be considered as defects. All of our English limestone fireplaces are individually made by English Heritage approved stone masons so they are validated by a personal endorsed certificate to underscore the authenticity.
