Specimens of Halite, collected from the Boulby Mine in Redcar, North Yorkshire, UK. Halite is a salt mineral, with a translucent colouration that includes orange, yellow or brown tinges. These specimens come in lots of approximately 550g, in a polythene bag. Pieces come in a variety of sizes

Please note dirt or clay may also be present, appearing as small brown inclusions within the mineral or on the surface of samples, as these were naturally picked out from the ground
