If you imagine the world as a kettle of boiling water, standing on a lit gas ring. While the steam escapes through the spout, all is well. But if the spout and lid was to become blocked, the steam would create a growing pressure inside the kettle. Eventually, the kettle would burst and the pressure is suddenly released. A bursting kettle is like an erupting volcano, releasing some of the pressure that had built up below the mantle.
Me because I am so hot
The pressure within the stiffer mantle ranges from about 14 GPa (gigapascals) at the upper boundary to over 136 GPa at the core-mantle boundary. This high pressure contributes to the solid-state behavior of the mantle material despite its high temperature.
The high pressure in the Earth's mantle, estimated at around 725,000 pounds per square inch (50,000 atm), is what allows diamonds to form. This pressure is combined with high temperatures and specific carbon-containing fluids in the mantle, which lead to the crystallization of diamond.
High temperature and high pressure are inferred to occur within Earth's stiffer mantle. As depth increases in the mantle, both temperature and pressure increase. This combination of high temperature and pressure allows for the solid rock to exhibit ductile behavior, resulting in the flow of solid material over long periods of time.
The weight of the rocks above the mantle results in high pressure.Diamonds need high temperatures and pressure to form from carbon. Diamonds form in the mantle in certain zones where conditions are right for them to do so.There just happens to be the right critical temperature-pressure-mineral environment in the mantle in certain zones for their formation.

YES! Neptune does have a mantle. Neptune's mantle is believed to be enriched with icy water, ammonia and methane. These elements create a high pressure.

Diamonds are made naturally deep within the Earth's mantle under high pressure and temperature. However, diamonds can also be created in a lab using high pressure and temperature to mimic the conditions in the Earth's mantle. This process is known as chemical vapor deposition or high-pressure high-temperature synthesis.
The melting temperature of materials is dependent on the pressure that is applied, whereby the higher the pressure, the higher the melting temperature. As such the rocks in the mantle are experiencing such a high pressure, that their melting point is driven up beyond the temperature within the Earth's mantle so they remain solid.
The lower mantle remains solid due to high pressure, which increases the melting point of minerals. The pressure at such depths is so immense that it keeps the minerals stable in a solid state despite the high temperatures.
Because towards the center of the earth, there is more mass on top of it, so there is more pressure. All of the other layers, and the stuff on top of the earth is pushing down on it from all sides. For the mantle, its only the stuff on the top of the earth that is putting pressure on it.
The mantle isn't 100% liquid because magma solidifies near the crust and becomes plastic in texture and not fluid but eventually cools down to form the lithosphere. Lower parts of the mantle are not liquid because the high pressure keeps rock from melting.
