crystals

  Crystals are homogenous solids formed by a repeating of three dimensional atoms, ions or molecules and having fixed distances between constituent parts. In other words, crystals refer to a pattern that occurs in many materials and helps create gemstones like diamonds and quartz. Crystals are formed through the process of nucleation which can either be assisted or unassisted. What pretty much happens is fluids form into crystals as their atoms move closer together and with the help of changes in pressure and tempurature. The history of crystals is very interesting, the first people to find crystals i believe were mayans and aztecs. They were made to make very fine jewelry. The aztecs were interested in making crystal skulls.
