Crystalline Insulin

            The crystal structure occurs in all classes of materials, with all types of chemical bonds. Almost all existing metal bonding on a polycrystalline state; amorphous or single-crystal metals must be produced synthetically, with great difficulty. Crystal ionic bonds can be formed during solidification of salt, either liquid or condensation of molten solution. Covalent crystals are also very common. An example is the diamond, silica, and graphite. Polymer materials generally will form crystalline parts, but the lengths of the molecules usually prevent complete crystallization. Weak Van der Waals style can also play a role in the crystal structure. For example, this is the type of bond that unites the hexagonal patterned layers on graphite.

Gallium, a metal easily form a large single crystal

            Although the term "crystal" has the meaning specified in the materials science and solid-state physics, in everyday life "crystal" refers to solid objects that show certain geometric shapes, and often bad in the eyes. Various forms of the crystals can be found in nature. The forms of these crystals depend on the type of molecular bond between the atoms to determine the structure, and also the creation of the state of the crystal. Snow flowers, diamonds, and table salt are examples of crystals.

            In any crystal color emitted, bring its own beauty. Twinkle-twinkle crystal light gives luxury and glamor impression. That's why it made ​​crystal jewelry and accesories that charming. Crystals color are very diverse. The colors of the crystals are also following months:
