The rock has undergone metamorphism. Metamorphism is the process in which the mineral composition and texture of a rock change in response to heat, pressure, or chemical reactions. This can result in the formation of new minerals and changes in the rock's appearance and physical properties.
Subduction and high pressure.
Prograde metamorphism refers to metamorphic processes that occur as rock is buried deeper in the Earth's crust and experiences increasing temperature and pressure. This leads to changes in mineral composition and texture as the rock undergoes metamorphism.

When there is directed pressure on a rock, regional metamorphism may occur. This type of metamorphism occurs due to tectonic forces, such as continental collision or subduction, which result in high pressure and temperature conditions that alter the mineralogy and texture of the rock over large areas.
When directed pressure is applied to a rock, it can cause the minerals within the rock to realign in response to the stress, leading to metamorphism. This process can result in the formation of new minerals, changes in texture, and the development of foliation within the rock. Metamorphism occurs at elevated temperatures and pressures below the melting point of the rock.

No, jadeite is a natural mineral that is formed from high-pressure metamorphism of serpentine rock. It is not man made.
Pressure required for metamorphism is generated by the overlying rock layers or tectonic forces exerted on the Earth's crust. These forces cause compression, which leads to an increase in pressure within the rock, ultimately resulting in metamorphic changes. Additionally, the weight of overlying rocks contributes to the pressure required for metamorphism.
Either by melting or by deposition.
Metamorphism involves the combination of high temperature and pressure acting on the existing rock to change its mineral composition and texture. These conditions can alter the rock without completely melting it, leading to the formation of metamorphic rocks.
