To Willy, diamonds represent tangible wealth and, hence, both validation of one’s labor (and life) and the ability to pass material goods on to one’s offspring, two things that Willy desperately craves. Correlatively, diamonds, the discovery of which made Ben a fortune, symbolize Willy’s failure as a salesman. Despite Willy’s belief in the American Dream, a belief unwavering to the extent that he passed up the opportunity to go with Ben to Alaska, the Dream’s promise of financial security has eluded Willy. At the end of the play, Ben encourages Willy to enter the “jungle” finally and retrieve this elusive diamond—that is, to kill himself for insurance money in order to make his life meaningful.
