Minerals differ in colors although most of them have a specific color range.

However, some minerals have alternate color when they are grounded to powder than their natural attribute. This is the more reason why Geologists and other mineral researchers make use of tiles of unglazed porcelain usually referred to as a ‘Streak plate’ to discriminate minerals by their streaks. In another hand, they may have to scratch the mineral over a surface to get the real color as some amount of powder color is deserted when this is done.

Nonetheless, making using of streaks is a more dependable way of ascertaining a mineral identity than colors. Despite the fact that the mineral examples are diverse in colors, it leaves a rosy dark colored streak when scratched over a streak plate.

The streak is the coloration of a mineral in the form of a powder. Luster refers to the absorption, mirror image, or refraction of light by the surface of the mineral. Minerals have various lusters that are somewhat self-explanatory such as dull, earthy, metallic, silky, pearly, and resinous — also magnetism.

Certain materials exhibit magnetism or an attraction to a magnet, and some will display this property only when heated. Minerals possess physical properties which aid in identification.

Minerals are naturally occurring solid substances and are found in rocks. Actually, in order to meet the real definition of mineral, five substance requirements must be met, and these requirements are as follows: It must be naturally occurring, it must be inorganic, it must be solid, it must have a definite chemical composition and its internal structure must be in order or with a pattern. Without meeting these five requirements, geologists do not label it as a mineral.

There are different kinds of minerals which vary in density, form, size, hardness, transparency and location. Some are radioactive or magnetic, while others are uncombined elements such as copper, gold, silver and diamond.
