Muscovite mica is a common mineral often found in many other rocks. It is sometimes also known as common mica and is easily identifiable due to its perfect basal cleavage which result in specimens forming with thin laminae (sheets) which are often referred to as a 'book'. These mica sheets also have a certain point of elasticity to them, being able to be bent and returning to their original shape. It is also know because of it's metallic lustre, which gives the surface of said sheets a reflective nature. Many children will often refer to mica or rocks which include a lot of mica as being like a mirror. A soft mineral, ranking between 2 and 3 on the Moh's scale of hardness, it can be easily scratch, broken or even cut with scissors if the sheets are thin enough. Our samples were collected by staff from Norway and come from Iveland, Southern Norway. We can supply pieces in three sizes but thickness will vary from thin transparent specimens to thicker opaque ones. Each specimen will be supplied in a card tray with an information label.
