A common version of the saying in Spanish is echar margaritas a los cerdos, lit. ' to cast daisies before swine ' . This comes from translating Greek μαργαρίτας ( margarítas ) as its Spanish false friend margaritas ("daisies").
Diamonds are not formed from highly compressed coal. Almost all commercially mined diamonds were formed in the conditions of extreme heat and pressure about 150 kilometers (93 mi) below the earth's surface. Coal is formed from prehistoric plants buried much closer to the surface, and is unlikely to migrate below 3.2 kilometers (2.0 mi) through ...
The operation of the diamond anvil cell relies on a simple principle: =, where p is the pressure, F the applied force, and A the area. Typical culet sizes for diamond anvils are 100–250 micrometres (μm), such that a very high pressure is achieved by applying a moderate force on a sample with a small area, rather than applying a large force on a large area.

It is possible to treat regular diamonds under a combination of high pressure and high temperature to produce diamonds that are harder than the diamonds used in hardness gauges. [30] Diamonds cut glass, but this does not positively identify a diamond because other materials, such as quartz, also lie above glass on the Mohs scale and can also ...

Since diamonds have high strength and low reactivity with either the inclusion or the volcanic host rocks which carry the diamond to the Earth's surface, the diamond serves as a container that preserves the included material intact under the changing conditions from the mantle to the surface. Although diamonds can only place a lower bound on ...
