by SouthPhiladelphia » Oct 19, 2011 I came across the following: http://www.diamonds.net/news/NewsItem.aspx?ArticleID=37366 Polished Diamond Prices Drop by 8.6% in Third Quarter RapNet Diamond Index Falls 4.5% in September Oct 5, 2011 9:32 AM By Rapaport ... In September the RapNet Diamond Index (RAPI) for 1.00 ct. polished diamonds fell 4.5 percent to 99.57. The 0.50 ct. category declined by 4.5 percent to 36.47, and 3.00 ct. dropped 0.9 percent to 168.04. The third quarter of 2011 has been one of decline for diamond prices following a positive first half of the year: RAPI for 1.00 ct. diamonds fell 8.6 percent, while 0.5 ct. stones declined 7.5 percent, and 3.00 ct. diamonds dropped 5.8 percent. ... But am being told by a vendor I am working with that they are raising their prices on polished stones 2-3ct as of next week? Sales tactic or reality?
