The IDEX Online Polished Price Report – April 2018

(IDEX Online News) – There were relatively few price changes in round diamonds in April, particularly in smaller diamonds under 0.50 carats. Diamonds of 1-2 carats saw some downward movement, while larger diamonds saw significant upward movement. This was particularly evident in 3.00-3.99 carat stones and, to a lesser extent, in the 4.00-4.99 and 5.00-5.99 carat categories.

Fancy diamonds also saw relatively few price changes in diamonds of less than 0.5 carat. The 0.70-0.79 category saw declines of 2-3%, and the 0.80-0.89 carat category saw rises in E-K, SI1-12, while 0.90-0.99 carats in D-J, IF-I2 showed notable increases, as did the 1.25-1.49 carat category in D-E, IF-VS1, and in 5.00-5.99 carats L-N, SI1-SI2.
