The Great Laxey Mine was a silver, lead ore and zinc mine in Laxey, in the parish of Lonan, Isle of Man. The mine exceeded a depth of 2,200 ft (670 m) and consisted primarily of three shafts: the Welsh Shaft, the Dumbell's Shaft and the Engine Shaft; each of these shafts was connected by a series of levels. The mine holds the world record for the largest sulphide crystal (measured by both volume and mass), being a sample of galena (PbS) weighing 118kg. This sample is on permanent display in the geology galley of the Natural History Museum, London. The specimen is composite cubo-octahedra, measuring 25 x 25 x 25cm.
