It occasionally is found as nuggets as large as 12 millimetres (0.5 inch) in diameter, and on rare occasions nuggets of native gold weighing up to 50 kilograms are found—the largest having weighed 92 kilograms. An ion is a mineral or element that has a positive or negative charge. The most common mineral mistaken for gold is pyrite. All the properties of a mineral - its crystal shape, hardness, colour, lustre - depend on which chemical elements it is made of and how the atoms of these elements are arranged inside it.
