Anvils are typically 3-4 mm in diameter with 1/4 to 1/3 carat weight and cost about $1000. They can be used for a large number of experiments.
A diamond anvil cell (DAC) is a high-pressure device used in geology, engineering, and materials science experiments. It enables the compression of a small (sub-millimeter-sized) piece of material to extreme pressures, typically up to around 100–200 gigapascals, although it is possible to achieve pressures … See more The operation of the diamond anvil cell relies on a simple principle: $${\displaystyle p={\frac {F}{A}}}$$ where p is the pressure, F the applied force, and A the area.
