The IDEX Online Polished Price Report – January 2018

(IDEX Online News) – For the first time in many months, there was a clear upward trend in prices of round diamonds in January with most categories showing rises. This was particularly the case with the 0.30-0.39 to 0.70-0.79 carat categories.

There were relatively few decliners, although 0.45-0.49 carat diamonds in the L-M, IF-VVS1 category saw decreases of 2-3 percent, with similar declines in the 1.25-1.49 category in E-F, IF-VVS1 clarities.

Fancy diamonds saw relatively few price changes, with more of a mix of both upward and downward trends. There were decreases in a range of colors and clarities in 0.30-0.39 carat diamonds of 2-4 percent, and in several color-clarities in 1.50-1.99 carat stones, and in the 2.00-2.99 and 4.00-4.99 categories.

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