Hand in hand with money comes materialism, which stems from the desire for not only wealth or privilege but things that will display one’s wealth. Hence Gatsby’s house, with its hired orchestra and absurdly beautiful music rooms. Perhaps the best example of materialism is Daisy’s acceptance of the pearl necklace worth $350,000 that Tom gives her. Her affections are effectively bought by this necklace and by the promise of more like it. Daisy wants nothing more than to be safe and secure financially. That is why Gatsby has to be rich in order to win her back. Her materialism is more important to Daisy than his love, whereas his love is more important to him than materialism in general. This is the essential difference between Gatsby and Daisy.
