(IDEX Online News) - As in November, there were relatively few price changes in round diamonds in December but most of the changes were upwards, particularly for stones of around 0.70 carats to 2.00 carats. There were rises in a range of 0.40-0.44 carat and 1.00-1.24 carat diamonds. There were declines of 4 percent, in 0.18-0.22 carat stones in the SI1-SI2 category, as well as in 0.23-0.29 carat diamonds in mid-level colors and clarities, and in 2.00-2.99 carat goods in D color in I1-I3 clarities.
Fancy diamonds also saw relatively few price changes, and as with rounds, most of the changes were upwards. There were increases in a range of colors and clarities in 0.30-0.39 carat diamonds, and in top color-clarities of 0.70-0.79 carat stones, and in E-J colors, SI2-I2 diamonds in the 5.00-5.99 category. Meanwhile, there were declines in the 0.30-0.39-carat category in D-E, VS1 to VS2 goods, and in several categories of 1.50-1.99 carat stones.
