Industry analyst Edahn Golan on whether the diamond market is grinding to a halt, Rio Tinto's withdrawal from Zimbabwe, continued manufacturing woes and a ray of sunshine with increased U.S. jewelry sales. One key indicator to watch is De Beers' next Sight. Sightholders are deferring up to 25% of purchases until the August Sight, and DB has already lowered its sales estimate for July, citing 'shortages'. Golan wonders if these shortages are really a way to cut supply a little without saying so outright, and suggests that all eyes should be focused on a potential showdown in August. In short, "The takeaway is that the entire diamond jewelry pipeline is in deep crisis."
