[打卡] 钻石的价值如何衡量？

今天的外刊金句来自《经济学人》“钻石价格暴跌的背后”：

Its precise value is determined by how well the stone is cut, its colour, its size and whether it contains flaws.

1. precise: adj.确切的、准确的
2. is determined by：被...决定、取决于...
3. flaw: n.瑕疵
   

1. how well the stone is cut 和 whether it contains flaws 都是名词性从句，可以理解为两个“大名词”。
