 What are Crystals?

The definition online says that Crystals are:

1. A piece of a homogeneous solid substance having a naturally geometrically regular form with symmetrically arranged plane faces.

2. Any solid consisting of a symmetrical, ordered, three-dimensional aggregation of atoms or molecules.

But they are so much more than that. A crystal was formed by a volcano. I won’t bore you with the details of Nucleation; suffice to say that when magma or molten rock cools, crystals are produced. The slower it cools, the larger the crystals that are produced.

For example, diamonds, a very expensive crystal (also one of the hardest substances known to man) are formed quite deep in the earth. There are lots of carbon atoms present in diamonds, so they are made from mainly carbon-rich rocks. The pressure pushes the carbon atoms together, to from diamonds, which then are inside the molten rock.
