The diamond industry has been on something of a rollercoaster ride since the global financial crisis of 2008, with prices plummeting in 2008 and 2009, before rebounding to reach historically high levels in 2010 and 2011. This pattern of extremes was replicated in 2012, with retail sales of diamonds growing 1.8 percent from 2011 to $72.1 billion at the same time that overall prices for rough and polished diamonds declined by 14 percent and 13 percent respectively.
