Diamonds.

Diamonds are essentially highly compressed carbon atoms. They Form around 200 kilometers below the earths surface at extremely high temperatures. Once they form they eventually get brought to the surface through mining or volcanoes. Yet diamonds can be made synthetically too. This is done by putting carbon-containing substances in a pressurized molten metal. Carbon normally comes in the form of graphite and its molecular structure is sturdy at around stp, however once higher temperatures and pressures are applied, the molecular structure of a diamond is more stable. The catch is that once the diamond is cooled the structure doesn’t break apart and stays together. Diamonds are notorious for being crystal clear. Yet some of the most prized diamonds are in colored. Color is not as many would thing a trait of perfection, but a flaw. The colors are part of impurities, these impurities give them tinges. Diamonds reflect a large part of the light that hits it and traps another large part, giving it the shiny yet multi colored appeal. Diamonds also have another interesting property. They are poor electric conductors, but amazing heat conductors. This explains why the diamond feels cool to the touch.

There where no real difficult terms in this article.

I have no personal opinion in this matter, due to the fact I am broke and have no way to possibly afford a diamond. However, I am well aware that diamonds cut glass, so that must mean they are extremely hard.
