We first want to apologize that, due to space limitations, our English version did not translate all of the Chinese text, thereby omitting a couple of points raised in your letter: 1) The composition and manufacturing methods of the Soviet diamond, and 2) The words of a gemmologist stating that the Soviet diamond is merely a substitute for synthetic diamond and that only that made by General Electric is truly synthetic.
首先我們要道歉的，是因為篇幅的關係，英文並沒有把全部中文譯出來，它省略的部分，包括了您信中提到的兩點：一、蘇聯鑽的成分與製造方法。二、一位寶石專家說，蘇聯鑽只能算是人造鑽石的替代品；唯有奇異公司產生的才是人造鑽石。
