Granite with larger crystals, basalt with smaller crystals.
Intrusive rock normally has visible crystals. Extrusive igneous rock has small crystals. A black extrusive igneous rock with small crystals could be basalt.
The size of the crystals in an igneous rock tells us how fast the magma cooled.
The rock with crystals inside in can be igneous rock, but no, idk about the minerals.

yes
The size of the mineral crystals in an igneous rock determines the rock's texture.
The size of crystals in an igneous rock is called texture. Texture can range from fine-grained (small crystals) to coarse-grained (large crystals).
Well The Igneous Rock: When it Forms Underground the Pressure combines with Large crystals :)
Igneous rocks can have both small and large crystals, depending on how quickly they cool. If an igneous rock cools slowly beneath the Earth's surface, it can form large crystals, while rapid cooling at the Earth's surface or in an eruption can result in small or no visible crystals.
If you're not looking for anything specific, any extrusive igneous rock will have smaller crystals, if any at all. This is because they cool quickly on the surface, leaving little time for crystals to form/grow.
igneous rock
Extrusive igneous rock consists of mineral crystals that are not observable with the naked eye. Obsidian is an extrusive igneous rock (volcanic glass) where there technically are no mineral crystals.
