When it was first established that diamonds are made out of quite normal carbon - the same element that constitutes coal - most people had a hard time believing this simple scientific fact.

And when the hardness of diamonds was measured, the fact proved hard to swallow too, for diamonds are the hardest things in existence; they are so hard that it takes a diamond to cut another diamond, and nothing else will work, except for a laser beam.

Today we have natural and artificial diamonds which are almost indistinguishable, except for one detail: synthetic diamonds turn fluorescent under ultraviolet (UV) light. If you put an artificial diamond under a lamp that emits light in such a wavelength, it will start to glow, while natural diamonds will not.

The cristaline structure in both cases is the same, essentially, but there is a slight difference in both: in natural diamonds, carbon atoms are perfectly aligned on three axis, forming rows which are geometrically the same whether you look up, down, left, right, forwards or backwards. However, in the case of artificial diamonds this is not the case, and this slight difference causes the UV glow that we have just mentioned.

Both kinds of diamonds have been created under conditions of extreme temperature and pressure, but natural ones have been exposed to such conditions for much longer; thus, the atoms had more time to accommodate inside the structure, filling all void spaces.

To find diamonds is one of the dreams of many a explorer, and even many wars took place because people were looking to control diamond sources: starting with the Boer war, the African continent has witnessed dozens of conflicts related to mineral sources and with the only and specific goal of controlling diamond mines.
