My dear friend, Mathilde. Let me tell you something. That necklace you borrowed from me wasn't a real diamond necklace. It wasn't valuable at all. The stones in the necklace were made of glass. It was worth five hundred francs at the most.

玛蒂尔德，我亲爱的朋友。让我告诉你吧。你向我借的那条项链并不是一条真的钻石项链。那条项链根本不值钱。项链中的宝石是玻璃做的。它最多值500法郎。
