luster
Color is the least reliable diagnostic mineral property because many minerals come in different varieties. For instance, amethyst and smoky quartz are all forms of quartz. Therefore, color may hint at the type of mineral but should be used in conjunction with other tests such as hardness and crystal form.
Color is the most unreliable diagnostic property of minerals like quartz because it can be easily influenced by impurities, resulting in varying colors. This makes color alone insufficient for accurate mineral identification.
streak
Color: Hue of a mineral, often observed in its visible spectrum. Hardness: Resistance of a mineral to scratching or abrasion, measured on the Mohs scale. Chemical composition: Elements that make up a mineral's structure. Streak: Color of a mineral's powder when scratched on a surface. Luster: Manner in which light reflects off a mineral's surface. Fracture: Manner in which a mineral breaks when not along cleavage planes. Diagnostic property: Characteristic feature used to identify a specific mineral. Uses: Applications of minerals in industries such as construction, technology, and jewelry.
Color is a mineral property that can be determined simply by observation.
Metal
The shininess of a mineral is known as it's luster. It is one of the many physical properties that are used to help classify minerals.
Luster- how light reflects of an object (usually a mineral).

The shininess of the metal is known as its luster. Luster refers to the way light interacts with the surface of a mineral, rock, or metal, and it can vary from metallic to dull.
A primary property is one that all minerals possess, whereas a special property is found in only one or a few minerals.
The most diagnostic physical property of a mineral is its hardness, which is measured on the Mohs scale. Hardness indicates how resistant a mineral is to scratching and can help distinguish between different minerals. For example, talc is the softest mineral on the scale (1), while diamond is the hardest (10). Other important properties include color, luster, and streak, but hardness is often the most reliable for identification.

The type of mineral property used to observe the color of the powder on an unglazed tile is called streak. When a mineral is scratched against the tile, it leaves a powdered residue that can reveal its true color, which may differ from its appearance in larger crystals or specimens. Streak is an important diagnostic property in mineral identification.
The property you are referring to is called luster. Luster describes how light is reflected off the surface of a mineral, and can be categorized as metallic, glassy, pearly, dull, or earthy, among others. It is an important diagnostic characteristic used in mineral identification.
