IDEX Online Polished Price Changes – October 1, 2015

(IDEX Online News) – Once again, there were many price drops in round diamonds. Goods between 0.3-0.9 carats saw the most changes, with the majority of declines taking place in the medium to better clarities. Diamonds 5 carats and above were more positive, with price increases of up to 4 percent in certain categories.  

There were relatively fewer price changes in fancy-cut diamonds this week. Smaller goods saw more price drops, although they were generally few in number. Compared to round diamonds, the overall picture of fancy goods is more stable.

Following are some of the main changes in this week's IDEX Online Diamond Price Report.
