Sure, one way to understand this is to think about the conditions where they are most commonly found.  Many pearls are formed by a tiny crustacean (known as a “clam”) eating a piece of oyster flesh, and then getting stuck as it grows and matures.  During this time, it “swims around” in the oyster shell, until eventually it dies and a bead of the shell grows into a pearl.

Why pearls are popular?
user
Pearls are still popular because they are an unusually rare type of gemstone, and their unusual properties and association with wealth, royalty and exotic travel makes them a great symbol of beauty, luxury, and wealth.  In some parts of the world they are considered a good-luck charm, as well.  When they are presented to someone as a gift, they are often seen as a token of love and admiration, just as an engagement ring would be in modern times.
