The IDEX Online Polished Price Report – March 2018

(IDEX Online News) – There were relatively few price changes in March, with an equal mix of risers and decliners. There were a particularly small number of changes in categories under 0.50-0.69 carats, while diamonds in the 2.00-2.99 carat, 4.00-4.99 and 5.00-5.99 carat categories saw many risers than decliners.

Fancy diamonds also saw relatively few price changes, particularly in the smallest categories of under 0.45-0.49 carats and larger diamonds of 4.00-4.99 carats and 5.00-5.99 carats. Diamonds of 0.50-0.69 to 2.00-2.99 carats carats saw a clear downward trend.
