The irony is the fact that the woman worked her entire life to buy a necklace for the woman after it was lost to find out later on that the necklace she had lost and spent all that time trying to replace was fake... Also, the fact that the woman had merely wanted to wear the jewelry to make herself look more pretty and rich for the party...If she hadn't of asked her friend to let her borrow the jewelry, she would never have ruined her life by trying to make up for what she had done earlier on...
