The price of certified polished diamonds continued to rise in May, according to Rapaport Corp.
Improving retail sales in emerging markets and the U.S. shortages of excellent cut stones supported the price increase.
The RapNet Diamond Index for 1 ct. diamonds increased by 7.5 percent in May. Half-carat diamonds increased by 8.3 percent and 3 ct. stones increased by 7.7 percent. The Composite RapNet Index increased by 7.7 percent to 166.63.
Diamond prices continued to increase in May despite a slight pullback in demand, according to the Rapaport Research Report “Where the Buck Stops?,” which is available here.
