Diamonds are nevertheless classified as minerals, because they adhere to the five core characteristics of minerals. In addition to being formed by a natural process, minerals are stable at room temperature. This simply means that all minerals are solid at normal temperatures and pressures common on the Earthâs surface. This characteristic excludes water from being a mineral because of its liquid state but includes the solid form of water â ice â as a valid mineral. Minerals are also represented by a chemical composition or atomic structure. Minerals all share a uniquely orderly internal order.
Chemical Composition --Minerals are chemicals, either elements or compounds found naturally in the Earth. Some minerals have a fixed chemical composition, and some minerals have a rigid set of chemical composition parameters that allow for the replacement of certain elements with other elements.Chemical properties can be tested with the use of a blowpipe, flame color, bead test, and laboratory solution tests.n a hand sample/specimen you can the properties used to identify minerals are luster, diaphaneity, color, streak, luminescence, play of colors, crystal shape, tenacity, cleav â¦ age, hardness, specific gravity and density, magnetism, electrical properties, reaction to acid. 18 people found this useful.
