What is the resolution of the story the necklace?

Answer: "The Necklace" occurred when Mathilde confessed Madame Forestier about what actually happened the night of the ball and how her life had been altered ever since. Madame Forestier then revealed that the proclaimed "diamond" necklace was actually costume jewelry.

Explanation:

The necklace symoblized greed and how it can cloud one's judgement if you allow it to control your life. This is exactly what Madame Loisel allowed greed to do. In the end, it backfired and she was left with the notion that contentment in one's life is a vital and necessary component.

The necklace is returned; however, it takes the Loisels ten years and much hard work to repay the loans. One day on the street, Mathilde meets Madame Forestier, the owner of the necklace. Mathilde confesses to her what she and her husband had been through: ... it has taken us ten years to pay for it.
