A rock structure is made out of any type of rock. A rock structure can be man made but is usually naturally made, caused by weather or erosion.
Magma is molten rock beneath the Earth's surface. Sediment is small particles of rock or organic material that have been broken down through weathering and erosion. Sedimentary rock forms when these sediments are compressed and cemented together over time.
Volcanic glass or obsidian is a quickly cooled igneous rock without a mineral crystal structure.
texture. Texture describes the relative size, shape, and arrangement of mineral grains or crystals within a rock, which can range from fine and smooth to coarse and rough. This characteristic is helpful in identifying and classifying different types of rocks.
Igneous rocks typically contain crystals within their structure.
Igneous rock is generally hard rock because it forms from the solidification of molten magma below or at the Earth's surface, resulting in a crystalline structure that is dense and strong. However, the hardness can vary depending on the specific mineral composition and cooling history of the rock.
Oregon's state rock is the thunderegg. However, geologists point out that it isn't really a rock; they define it as a "structure," either a nodule or a geode. When the Oregon Legislature designated the thunderegg as the state rock in 1965, they also decreed it to be an "honorary rock," thereby getting around this problem of definition.

Please further define what you mean by 'crystal rock'.
the structure of an igneous rock is metamorphic rock that has been heated rapidly and turned into magma then cooled to create igneous rock its gay

Rock containing halite as its main constituent.
The common structure of a metamorphic rock is that there are several pieces of different types of minerals, sand, rock, or glass.
