The physical properties of minerals include name, crystal system, color as it appears to the naked eye, streak by rubbing on streak plate, luster, hardness on the Mohs scale, and average specific gravity. The chemical properties comprise chemical formula and the proportion of elements in the purest form of
ContactPolymorphism. Physical properties of minerals are directly related to their atomic structure, bonding forces and chemical composition. Bonding forces as electrical forces exist between the atoms and ions are related to the type of elements, and the distance between them in the crystalline structure. Thus, minerals having same chemical

Some minerals are so alike to each other in other properties that the only way to tell them apart is by doing a specific gravity test.
ContactThe hardness of a mineral is a way of describing how easy or difficult it is to scratch the mineral. It is used, in combination with the other physical properties, to help identify a mineral specimen. Luster. Luster is a description of the way a mineral surface looks when light reflects off of the surface. Specific Gravity
ContactMost minerals are heavier than water, and the average specific gravity for all minerals is approximately 2.7 (a density of 2.7 g/cm 3 ). Some minerals are quite heavy, such as pyrite with a specific gravity of 4.9-5.2, native copper, with a specific gravity of 8.8-9.0, and native gold at 19.3.
ContactPhysical Properties of Minerals A mineral is a naturally occurring solid formed by inorganic processes. Since the internal structure and chemical composition of a mineral are difficult to determine without the aid of sophisticated tests and apparatus,the more easily recognized physical properties are used in identification.
Contact2019-9-14 The common mineral luster categories are adamantine, dull, glassy, greasy, pearly, resinous, silky, vitreous and waxy. This physical property of a mineral can be quite helpful in identification. Many minerals that might look the same will have a very different light reflective surface. Some examples of mineral luster can include chert which has
Contact2022-5-16 Physical Properties of Minerals: 1. Colour: The colour of any object is a light dependent property- it is the appearance of the particular object in light (darkness destroys colour). A particular colour is produced by reflection of some and absorption of other components of white light. A mineral shows colour of that wavelength of the white

Contact2021-12-24 Luster. It means the physical property of minerals to reflecting visible light. The luster is measured by how much light they can reflect, and it can be divided into four levels. Metallic lustre. Pyrite and galena are of metallic lustre. Semi metallic lustre. Magnetite is an example. Adamantine luster.
Contact2021-7-27 An important physical property of a mineral is how light or heavy it feels relative to the size of the sample; its heft. The property that causes this observed difference is density, which is mass per unit volume. Minerals with a high density, such as gold, have closely packed atoms. Minerals with a low density, such as ice, have loosely packed
ContactElizabeth Johnson. The best way to practice observing and correctly identifying physical properties of minerals is by doing it in person. It is impossible to feel the relative weight of a mineral or the way it smells or tastes, for example. These exercises are meant as a selective review of some of the physical properties than can be observed.
Contact2013-9-16 Two minerals of note have differences in hardness depending on direction: Kyanite has a hardness of 5 parallel to the length of the crystal, and a hardness of 7 when scratched along a direction perpendicular to the length. Calcite has a hardness of 3 for all surfaces except the {0001} plane. On {0001} it has a hardness of 2.
