The loisels were living in France during the 19th century
Madame loisel is upset that she didn't have a nice dress so her husband buys one for her.
When madame loisel got her dress she needed a necklace so she went to her friend for it.
When madame loisel was at the party she lost the necklace and looked for it.
Madame loisel lost the necklace she lied about losing the necklace and told her that the band broke to give them some time to but a new one.
10 years went on and madame loisel and her husband had to pay back the money they owned and madame loisel saw her friend and talked to her just to figure out that the necklace she lost was paste and the one they bought was actual diamond
