Crown jewel—the best or the most valuable thing that a person or place has, the most valuable or attractive thing in a collection or group 御寶，最有價值之物

Examples:

  1. Prague’s crown jewel is the old town center.
  2. These two paintings are the crown jewels of the museum’s collection.

(Forbes, (2017/06/29) China took control of Hong Kong, which was once called the crown jewel of British colonies, to much fanfare 20 years ago. Clearly there’s much work to be done over the next two decades to ensure the city retains not just its shine but its significance.

20年前，中國在盛大慶典中接收了有英國[最有價值殖民地]之稱的香港。未來二十年有更多的工作等著，以確保這個城市不但表面繁榮，重要性也屹立不搖。

(New York Times, 2017/04/11)

Few companies have embodied Japan’s industrial might like Toshiba, whose products run the range from hair dryers to giant gas-fired electricity turbines, as well as nuclear reactors. But it has faced a spate of recent stumbles in core businesses as well as a scandal over falsified profits  that came to light in 2015.

Toshiba said it hoped the planned sale of shares in its chip division, its crown jewel, would alleviate the uncertainty over its future. While Toshiba has not said exactly how much of the business it will sell, even a minority stake is expected to be worth several billion dollars.

極少公司像東芝集團這樣體現了日本的工業力量，它廣泛的產品線從吹風機到天然氣推動的電渦輪機都有，還有核子反應爐。但是東芝的核心企業近來面臨一連串挫折，2015年甚至發生假財報醜聞。

東芝表示，希望能藉著賣掉它最值錢的記憶體部門股份，減輕公司未來的不確定性。東芝雖然沒公布打算賣掉多少記憶體股份，但即使只賣少數持股，價值應也有數十億美元。
