Intrusive igneous rocks have a shiny appearance because they form slowly, giving them larger crystals.
i think that igneous and metamorphic rocks uses luster because maybe they have it in them
because the magma does not have as much time for crystals to form inside the igneous rock therefor it is a fine-grained rock
yes it is shiny
It can be use for jewellery and stone age arrowheads, as the obsidian was much sharper when made into a specific shape. It can be sharpened to a very thin thickness. It is very shiny and is black. This is why Obsidian is common to be used in jewellery. Obsidian is igneous rock, which means that it was formed either inside (intrusive) or outside (extrusive) of the volcano. Igneous rocks are basically cooled lava, or magma.
It depends on the element. Some metals have very un-shiny appearences, and some non-metals are very reflective.

yes it is shiny
Most extrusive igneous rocks are usually shiny and smooth. This is because, they cool, solidify, and crystalize rapidly on the earth's surface, where there is less obstruction, and no enclosures.
shiny silvery and it a solid

Yes. That property i called luster.
