Solid metals are hard,shiny solids. They are good conductors of electricity and are malleable and ductile. In contrast to metals solid nonmetals are dull. Because they are brittle and powdery they are neither malleable nor ductile. The electrons in most nonmetals are tightly attracted and are restricted to one atom.

Mica has a non-metallic luster, one called vitreous or glass-like.
magnetite
Depending on the variety, feldspars can range from adamantine to glassy in luster.
You would need to look at the individual minerals. A rock does not have a luster.
1. They rarely have metallic luster. 2. They are usually gases at room temperature. 3. Nonmetallic solids are neither malleable nor ductile. 4. They are poor conductors of heat and electricity by Spencer Ferguson
No. It has a nonmetallic luster.
Augite has a nonmetallic luster.
Calcite is a compound and therefore cannot be classified as a metal or nonmetal.
Mica has a non-metallic luster, one called vitreous or glass-like.
Quartz has a nonmetallic, vitreous luster.
The two types of luster are metallic and nonmetallic. There is a an intermediate category known as sub-metallic. Some minerals even look like plastic.
I think its nonmetallic as it is glass
a ruby is nonmetallic
Gypsum
yes
magnetite
If a mineral has a shiny luster, is it matallicIf a mineral has no shiny luster, is it nonmetallic?
