A sales assistant reaches for diamond rings inside a display case at a Tiffany store in Shanghai, September 16, 2013. China's diamond market, now the world's second largest after the United States, has more than tripled to $22.8 billion over the last five years, according to data from market research firm Euromonitor, steadily gobbling up market share from gold and far outstripping the growth rate in China's 465 billion yuan ($76 billion) jewelry sector.
