The luster of a diamond is adamantine to waxy and is considered to have a metallic luster.
Does a diamond have a metallic or non-metallic luster?
Diamonds have a very bright luster – the highest non-metallic luster – known as “adamantine.” Their high luster gives them the ability to reflect a high percentage of the light that strikes their surface.
Is Diamond lustrous non-metal?
So, diamond is essentially non-metal. … Hence, the correct answer we are looking for is both iodine and diamond are lustrous non-metals. So, the answer is D. Note: Diamond as discussed has the highest non-metallic lustre; this is also known as “adamantine”.
Is Diamond A metallic mineral?
The nonmetallic minerals (carbon, diamond, coals, bitumen, asphalt, boron, sulfur, rock salt, etc.) lack the properties of the metallic minerals such as a bright metallic luster, hardness, density, and good conduction of heat and electricity.
What are the metallic luster?
Metallic luster is a property of a metal that describes the amount of light that reflects off the metal.
Does a mirror have a metallic luster?
Beside above, does a mirror have a metallic or non metallic luster? Metallic luster. If the sample reflects all light in a mirror-like (not glassy) fashion, then mineral may be (but might not be) metallic.
Which mineral is metallic?

Why Diamond is the hardest metal?
The outermost shell of each carbon atom has four electrons. In diamond, these electrons are shared with four other carbon atoms to form very strong chemical bonds resulting in an extremely rigid tetrahedral crystal. It is this simple, tightly-bonded arrangement that makes diamond one of the hardest substances on Earth.

What causes metallic luster?
Refraction is caused when photons bump into electrons, are absorbed, and then (very shortly thereafter) are re-emitted as they travel through a material. … As the electrons drop back down to a lower energy level, the photons are re-emitted, resulting in the characteristic metallic luster.
