What is an example of metaphor in the novel, The Widows of Malabar Hill?

“She wasn’t excited to leave her beloved home. But if she became Bombay’s first woman lawyer, that would string the beads back on the ruined necklace and turn them to diamonds” (235).

Here, Perveen’s ruined necklace is a metaphor for her failed marriage, and it situates the readers towards a hope that exists in the future.
