Examples of mineral characteristics: - density - hardness - refractive index - chemical composition - magnetic properties - cleavage - crystal system - radioactivity
Topaz is a hard mineral, ranking 8 on the Mohs scale of hardness, so it is harder than most common materials used to test streak. Since streak tests are typically performed on softer minerals, such as using a porcelain streak plate with a hardness of about 6.5, the topaz does not leave a streak because it is harder than the material being used for the test.
Cobalt has a cleavage in three directions, forming a cube.
No, not all minerals have cleavage. Cleavage is a property in which a mineral breaks along planes of weakness to form smooth surfaces. Some minerals exhibit cleavage, while others may fracture irregularly or have no cleavage at all.

Streak. The 6 properties of minerals are streak, hardness, crystal form, color, cleavage/fracture, and luster. Hope that can answer your question:)
Gneiss does not have a streak because it is a metamorphic rock composed of interlocking minerals with no cleavage. The streak test is typically used to determine the color of the powdered form of a mineral when rubbed against a streak plate, but this is not applicable to gneiss.
The most useful physical properties for identifying minerals are color, luster, hardness, cleavage, fracture, streak, and specific gravity. These properties help geologists distinguish between different minerals based on their unique characteristics.
