Treak Cliff Cavern is of international fame and geological importance. It has been a designated a Site of Special Scientific Interest for many years and by agreement with English Nature all the Blue John Stone deposits on the visitor route are preserved. However, Blue John Stone is regularly mined in Treak Cliff Cavern, from areas not seen by visitors. This is then crafted into fine jewellery, small bowls, ornaments and other decorative items.
