Luster is the way a mineral reflects in the light. Streak is the color of a mineral in powdered form.
Lithium is a soft, silvery metal with a metallic luster. Its streak color is white.
Hematite is typically a dark gray to black mineral with a reddish streak, while galena is a silvery-gray mineral with a cubic crystal structure. One way to differentiate between them is by performing a streak test: hematite will leave a reddish-brown streak, while galena will leave a gray streak. Additionally, galena is heavier than hematite and has a metallic luster.
The four properties of minerals are color, streak, hardness, and luster. Color refers to the outward appearance, streak is the color of a mineral when it's powdered, hardness is the resistance to scratching, and luster describes the way light reflects off the surface of a mineral.
Both streak and luster are properties used to identify minerals. Streak is the color of the powder left behind when a mineral is scraped against a harder surface, while luster describes how light is reflected off the surface of a mineral. Both properties can provide clues about the identity and composition of a mineral.
Minerals can be distinguished based on factors such as color, hardness, luster, cleavage, and streak. Using specialized tests like scratch tests and acid tests can also help differentiate between minerals. Additionally, mineral properties like crystal shape and specific gravity can aid in their identification.
The tests you can do is the streak test, the luster test,the finger nail test(which is scratching it ti see if its hard or not).
luster: Vitreous/ non-metallic streak: white. if you crush ruby, it will turn into white dust
A diamond is the hardest natural substance, scoring a 10 on the Mohs scale. It has a brilliant luster due to its high refractive index. The streak color of a diamond is colorless, as it does not leave a streak on a streak plate.

Minerals can be identified by such as their color, streak, luster, and their hardness. What does streak, and luster mean?Streak-- Is the color of a mineral's powder for example: talc is a mineral and it is also powder and its streak is white.Luster-- Is the way a mineral reflects light from it's surface for example: glassy, pearly, silky, metallic and earthy can be words to describe luster.
