(Yicai Global) July 29 -- Worldia Diamond Tools has become the first stock among the 25 shares that started trading on Shanghai's new Star Market last week that reached the new 20 percent daily price limit this morning. 

The share price of Worldia [SHA:688028], a Beijing-based diamond cutting apparatus maker, soared to the ceiling after 20 minutes of trading. All other 25 stocks also began the day higher despite the limit that was implemented today to restrict the large jumps experienced last week.
