Superb fluorite specimen collected in the Sutcliffe vein, Rogerley Mine.

The edges of the biggest crystal are 1,7 cm long. It presents a twin, and is of a gemmy quality. All is disposed on matrix.

Other smaller crystals are present, with galena crystals.

Some growth figures are visible on the faces, which remain brilliant. A strong fluorescence appears under UV light (long waves), and a very good dichroïsm apperas when lighted by natural light.

Overall size : 4,5 x 4 x 3,5 cm
