Is there a theme of material possessions in the short story "The Necklace?"

There is definitely a theme regarding the need for
possessions in "the Necklace." The young woman in the story, Mathilde, has a comfortable
life, but does not have the materials possessions (fancy clothes, servants, etc.) she
wishes she had. So she is ashamed of her life. It eats away at her. She cannot see
"It's not having what you want, it's wanting what you've
got."

When Mathilde and her husband are invited
to a ball, Mathilde laments over having no jewelry, but there is no money for it: her
husband works hard as a clerk, though he does buy her a new
dress.

So Mathilde goes to a friend (Madame Forestier) and
asks if she may borrow some of her jewels. Her friend readily agrees, and Mathilde goes
to the party feeling complete, wearing a "diamond" necklace. Having the jewelry about
her neck makes her feel special and complete.

When she
loses the necklace, Mathilde and her husband go into great debt to replace the jewels.
They have to do without; Mathilde has to work and can no longer enjoy the life of
comfort she once knew. She works herself into the ground, worries and scrimps, and she
ages physically beyond her young years.

At a later date,
running into Madame Forestier, Mathilde speaks about the necklace and relates what she
had never revealed before: that she had lost the jewels. Her friend is dismayed:
they were not real. Mathilde and her husband have lost years of joy
and comfort paying for gems made of paste, all because Mathilde believed that material
possessions would make her happy.
