Description

Details

Wolframite is a rare iron, manganese, tungstate mineral and as such is a major source of tungsten. It often forms in quartz veins in areas of intrusive granite and is a grey or black mineral with a prismatic crystal habit and a metallic lustre which makes it shine under certain light angles. The name is derived from the German "wolf rahm", the name given to tungsten by Johan Gottschalk Wallerius in 1747. The particular samples were collected many years ago from the now closed Carrock mine, in Mosedale, Cumbria, UK. However, large economic deposits have since been found in Cornwall where it is being actively extracted. These specimens are now rare and we have very few left, samples will be supplied in a small magnifier box.
