IDEX Online reports that there was only minimal movement in polished diamond prices across the entire month of November, with no significant price fluctuations. "Despite the onset of the global holiday season, which should stimulate demand for diamonds, polished prices continued their decline in November on a month-on-month basis, with prices sliding 2.3% from their October price." IDEX further states that November 2015 prices are down 6.7% as compared to November 2014, which is the second largest drop after the February figures. "The 'good news' if you can call it that, came in the 4-carat category, which saw prices increase 1.9% year-over-year." They conclude that the trend now is continually dropping prices, a steady pattern since August of this year.
