What are crystals?

 Q:   Ask a Question about What are crystals?       
What are crystals? Crystals are solid substances that are naturally formed into regular geometric, angular shapes.

All crystals can be classified into seven systems. Sometimes a crystal is formed when water evaporates, and substances dissolved in the water gradually grow into a crystal. Other crystals are formed under great pressure.

Diamond crystals are made when carbon dissolves in molten rock deep down below the Earth's surface.

The diamond crystallizes out and is later uncovered on the surface either by volcanic action or by erosion of the Earth's crust. Other valuable gems are formed in a similar way, and most of them contain compounds of aluminum.
