On her breast was a piece of showy artificial jewelery such as you buy in the Rue de Rivoli.

她的胸别着一块华丽的人造首饰， 就像你在里沃利街买的那样。

Even I myself began to know the want of money (I mean of ready money in my own pocket), and to relieve it by converting some easily spared articles of jewelery into cash.

自己也开始意识到缺钱（指的是自己口袋里的现钱），并通过将一些容易省下来的珠宝首饰换成现金来缓解它。
