when a mineral is broken, if it breaks with smooth shiny sides, then it shows cleavage.

Begin by taking a look at the mineral's color, Examine the mineral and take note of its surface features,Get out the materials needed for the hardness test (see Things You'll need), The number is the hardness, followed by the characteristics of a mineral of that hardness and an example, Next find out your mineral's luster,Now for the streak test, You can also identify a mineral by the way it breaks. If it breaks along a smooth, flat surface (such as mica), it has cleavage. If your mineral breaks along rough, jagged surfaces, it has fracture. Thats all you need to do.
