Seashells are the protective outer layer of mollusks, and pearls are formed within some types of mollusks as a defense mechanism against irritants. Pearls are created when a foreign object, like a grain of sand, enters the mollusk's shell and the mollusk secretes layers of nacre around it, forming a pearl. So, seashells provide the environment for pearls to be produced within certain mollusks.

How rare are pearls?
Natural pearls are very rare. They are, in fact, much more rare than diamonds. There is no scientific study available that definitively shows how rare a natural pearl is, but many experts believe it takes approximately 10,000 mollusks to find one fine natural pearl. However, in areas of Central America, there are places where natural pearls are much more prevalent. It is believe this is due to a higher parasitic concentration. Cultured pearls are not nearly as rare. In fact, all the pearls we see today in jewelry stores are cultured pearls. The natural pearl industry all but died nearly 100 years ago. Cultured pearls are pearls grown on farms where pearl mollusks are nucleated and then tended for a period of time, eventually producing a pearl.
You heard that Indians would find pearls in clams is this true?
Native Americans may have found "pearls" in clams, but those were not "pearls" as we would consider them today. Clams are non-nacreous mollusks and do not produce actual pearls. They produce what are known as "calcareous concretions", which lack the pearly luster associated with pearls as we know them. More likely, Native Americans found pearls in mussels not clams. Those that were near coastal areas may have also found and collected marine pearls, but not from clams.
