It wwhen by using high likewise as high temperature to carbon that man-synthetic diamonds were first produced likewise when numbers of more interesting discoveries. About any lesson once subjected to high may compact itself into the denser form, for instance, quartz, also known as silica or silicon dioxide will first adopt the denser form called coesite, then upon application of extra temperature, form stishovite. These ii forms of silicon dioxide were number 1 witnessed by high pressure experimenters, on the other hand found around nature and severity at the places of a meteor impact.

High pressure experimentation has led to the discovery of the types of minerals which are then believed to survive inside core of the Globe, like perovskite which is thought to make higher half of the Globe's bulk.
