Sometimes when a mineral is forming in the earth’s crust, it grows into a particular geometric shape. The shape of a crystal results from the way the atoms or molecules of a mineral come together as the mineral is forming. So, each mineral has its own crystal shape. This solid body have a characteristic internal structure and is enclosed by symmetrically arranged plane surfaces, intersecting at definite and characteristic angles. Fashioned snowflakes, flawless diamonds with glittering facets, the almost perfect cubes of salt grains are all fine examples of crystals bodies with a pattern of flat surfaces that meet at definite angles. The universe is full of almost all nonliving substances in the solid state form crystals. Crystals are ice, snow, sugar, salt and sulfur; in metals like gold, silver, copper, iron and mercury; in precious stone like zircon, emerald, topaz, ruby, and sapphire.

crystalline solids are made from salts. (I hope this is what you mean.) It is an ionic bond with an electronegativity difference greater then 1.7. Its generally a combination of a metal and a nonmetal. The structures formed are the crystals. Now if your just talking about quartz crystal or rubies or sapphires, just go to google and type in what are "these" made of?

Depends what kind of crystal. Diamonds are made exclusively from carbon atoms. Copper sulphate crystals are copper sulphate and water i.e. CuSO4 + 7H20
