Igneous rock.
Igneous rock contains minerals arranged in crystals and forms when molten rock cools and solidifies. Examples include granite and basalt.

The crystals in a rock are often referred to as mineral crystals. They are formed as the molten rock cools and solidifies, allowing minerals to crystallize and grow within the rock. The size, shape, and arrangement of these crystals can provide clues about the rock's formation and history.
A crystal is a solid state of a mineral, the crystalline shapes formed by minerals depend upon their molecular structure. Wheras it is possible for a mineral to be liquified within molten lava for instance, it does not form back into crystals until it cools under a process known as fractional crystallisation.
The visible shape of a mineral's pattern is called a crystal. Solidified minerals that are from a molten state have smooth faced, angular crystals.

Molten rock contains liquified minerals, some solid mineral grains, and dissolved gasses.
Completely molten rock would not contain any crystals. Most magmas, however, are a mixture of molten and solid crystals of some sort. It is possible that a magma could contain larger crystals of a specific mineral.
crystals form from molten rock as the molten rock cools. if the molten rock cools very fast then you may have small crystals growing or no crystals at all. if the molten rockk colls slowly then you then you have large crystals growing. this happens when the molten material is deep in the earth. examples of these types of crystals are Rubies, Emeralds, and Diamonds. crystals may also form when water is evaporated. salt crystals are an example as they form when salt water evaporates.
There are three types of rock - igneous, sedimentary and metamorphic. Igneous rocks formed directly from magma (molten rock flowing under ground) or lava (molten rock flowing above the crust). Granite is an example of what forms as magma cools slowly over a very long time, and obsidian forms when lava cools quickly, such as from contact with ocean water.
The size of the crystals is a function of the rate of cooling of the molten rock. The faster the molten rock cools, the smaller the crystals will be.
Crystals are naturally occurring solid materials with a specific chemical composition and regular atomic structure. Common crystals found in nature include quartz, amethyst, citrine, and pyrite. Crystals are formed through the solidification of molten rock material or the gradual deposition of minerals from solution.
