CZ only imitates a diamond's appearance; it is only a sly impostor of the genuine article. Incidentally, you might be interested to know that by the trained jeweler, CZ is usually easily identified by merely observing the polished stone under 20X magnification.
或許貴刊以及讀者們也樂於知道，一個受過訓練的寶石鑑定家，只要將 CZ 表面擦亮，即可在廿倍的放大鏡下辨別真偽。
