Petra Forecasts a Further Recovery in Prices of Gems (Update2) - Bloomberg.com: "Petra rose 9.3 percent, the most in a month, in London trading. Gem prices will “slowly and gradually strengthen,” the St. Helier, Jersey-based company said today in a statement, after a rebound of about 25 percent in the market for so-called rough diamonds from lows reached earlier in 2009. Trading conditions remain “challenging” for now, Petra said."
