Snails are born with their shell. As the snail grows, so does its shell -- in a spiral shape. New shell is added at the opening of the shell by the mantle. In the center of the spiral is the part of the shell that the snail began life with.
The shell is made from several layers. The thin outer layer is made from an organic substance known as conchiolin. The thicker layer underneath is formed from three layers of crystalline calcium carbonate, similar to the chicken egg of which you may be more familiar. The color of the shell depends on the types of food the snail is eating and also the type of snail.

How often does a snail change shells?
Snails don't change their shells. Unlike crustaceans, molluscs like snails keep the same shell throughout their lifetime. The shell is formed from secretions from the snails mantle, the flesh under the shell, and some snails (such as the giant African snails kept as pets) can be seen running their mouths along the edge of their shells, to build up another layer on the shells lip. The stripes that make up the pattern of a snails shell are the result of different compositions of shell material at different times.
