.What mood did "The Necklace" elicit from the reader at the conclusion of the story

I think this depends on who the reader is. In sudden emotion, Madame Loisel reveals her entire story of losing the necklace, replacing it, and working off the cost of the replacement ever since. In response, Madame Forestier replies that the original necklace contained not actual diamonds but rather fake diamonds, meaning the original necklace cost no more than 500 francs. The reader would have felt a strong sense of irony but the rest is subjective.
