Chang Hung-shih remembers that in a Californian antiques market in the early 1990s, a perfect nine-eyed dZi bead went for US $ 40,000, the same price as a BMW 525 sports car, whereas in Taiwan, a similar quality nine-eyed dZi sold for US $ 100,000.
張宏實記得，在一九九○年代初期的加州古物市場上，一顆品相完美的九眼天珠，可以賣到四萬美金，相當於一部 BMW525 跑車。而在台灣，同樣的一顆極品九眼更是喊價十萬美金。
