The IDEX Online Polished Price Report – February 2018

(IDEX Online News) – There was a clear downward trend in price changes in many categories of round diamonds in February, particularly in categories from 0.30-0.39 to 0.80-0.89 carats and 2.00-3.99 carats.

However, there were rising prices in the smallest stones of 0.18 to 0.29 carats, and in 1.50-1.99 carat diamonds.

Fancy diamonds saw relatively few price changes in the smallest categories, but there were decliners in the 0.30-0.39 and 0.40-0.44 categories, along with the 0.50-0.69 through to the 1.50-1.99 carat categories.

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