What is the luster for lead?
dull luster
Lead has a dull luster and is a dense, ductile, very soft, highly malleable, bluish-white metal that has poor electrical conductivity. This true metal is highly resistant to corrosion.
What is the color and luster of lead?

What does lead mineral look like?
Lead (element #82, symbol Pb) is a very soft, blue-gray, metallic element. It is primarily produced from the mineral galena. It has been used since antiquity.
What does lead look like in rocks?
Lead is a bluish-grey metal, whose freshly cut surface shows a bright metallic luster which, however, quickly oxidizes on exposure to the air. It is soft, may be scratched with the finger-nail, and makes a black streak on paper.
Is lead shiny or dull?

Can lead be shiny?
Lead is a considered a basic metal or post-transition metal. It is a shiny blue-white metal when freshly cut, but oxidizes to a dull gray in air. It is a shiny chrome-silver when melted. For example, the metal has a low melting point (327.46 oC) and is a poor conductor of electricity.
How soft is lead?
Lead is a very soft metal with a Mohs hardness of 1.5; it can be scratched with a fingernail. It is quite malleable and somewhat ductile. The bulk modulus of lead—a measure of its ease of compressibility—is 45.8 GPa.
