At the beginning of the story, Mathilde is characterized as a poor woman who always felt that she had a taste for the luxurious. She was never satisfied with what she had, poor that it was, and she always dreamed of wearing the best clothes and jewelry. When she has an opportunity to borrow some jewelry from her friend, she sifts through the jewelry box of gems and pearls before noticing a separate box that held the diamond necklace. For Madame Loisel, diamonds must have been the best in her eyes because he story states that she made an immediate decision to wear it once she saw it. She chose the diamond necklace because she thought that it was the most expensive piece in the collection and she wanted her night out to be up to her expensive standards. To water the answer down, she was greedy and prideful.
