it was formed from extreme pressure for a long time under the earth.
magma crystallization.
A rock is considered igneous if it formed directly from the cooling of molten rock.
during heat prusure and time it changers from quartz to smoky quartz
Quartz is a mineral not a rock. Fossils can be found associated with quartz in sedimentary rock not inside the quartz.

No. Diamond is formed in carbon.
YES
Quartz crystals typically grow hydrothermally, in hot, pressurized, silical solutions.
Quartz
Both coal and quartz are formed by inorganic processes. Coal is formed from the remains of plant material that undergoes decomposition and compaction over millions of years. Quartz is a mineral composed of silicon and oxygen, typically formed from the precipitation of dissolved silica in crustal rocks or hydrothermal fluids.
Quartz and feldspar are commonly found together in granite and gneiss.
Quartz.
rock salt and conglomerate
Flint, chert, and jasper are all microcrystalline forms of quartz, which means they are composed primarily of silicon dioxide. They are formed from the accumulation of tiny quartz crystals over time, giving them their compact and fine-grained appearance.
Quartz is a mineral that is formed by volcanic action. It is the second most common mineral. Feldspar is more common.
Rose quartz is formed when a small amount of iron is incorporated into a pure quartz (SiO2) matrix. The inclusion of iron (Fe2O3) in many minerals s responsible for the colors that are observed. Iron also turns quartz into Amethyst.
The formation of a cluster of well-formed quartz crystals likely occurred in conditions with enough space for the crystals to grow freely without interference. Slow cooling and consistent pressure are also key factors in producing well-formed quartz crystals with defined shapes and clarity.
