Look if is solid, is it formed in nature.
If you are starting with a mineral, there is no need to determine if it is a mineral. Minerals are naturally occurring inorganic solids, with a specific chemical formula and a crystalline structure. If the material in question does not meet this definition, it probably isn't a mineral.

Color: Observe the color of the mineral. Hardness: Use the Mohs scale to determine the mineral's hardness. Cleavage and fracture: Check how the mineral breaks. Luster: Determine if the mineral is metallic or non-metallic. Streak: Identify the color of the mineral's powdered form. Specific gravity: Measure the density of the mineral. Acid reaction: Test if the mineral reacts with acid.
The density of the mineral compared to the density of water will determine if it floats or sinks. If the mineral has a lower density than water, it will float; if it has a higher density, it will sink.
The Mohs mineral hardness scale.
The color of a mineral in powdered form is called the mineral's Streak

An index mineral is used in geology to determine the degree of metamorphism a rock has experienced.
