Color is the most reliable test for a mineral determined by the chemical composition of a mineral the same for all minerals in the same crystal system the same as streak

the most reliable test for a mineral determined by the chemical composition

Explanation:

A mineral is an inorganic compound which can be obtained after the mining process. These minerals are produced beneath the earth crust by the geological processes.

The color of the minerals is the indicative of both physical and chemical properties. Two or more minerals can be similar in appearance on the basis of similarity in the outer color. But they are actually different.

Chemical tests can be done on minerals so as to know their actual color and can be used in distinguishing them. As various minerals can differ on the basis of their internal chemical composition, some impurities present in minerals can also provide them a color.
