RAPAPORT… PRESS RELEASE, June 10, 2014, New York… Diamond markets were quiet with stable prices in May. The trade focused on the U.S. ahead of the JCK Las Vegas show that took place May 29 to June 2. Polished diamond trading at the show was in line with expectations with steady U.S. demand for affordable VS-SI commercial-quality diamonds. Demand for better-quality large stones was relatively weak. Far East demand was quiet despite robust jewelry sales during the May Day holiday.
The RapNet Diamond Index (RAPI™) for 1-carat diamonds fell 0.4 percent in May, while RAPI for 0.30-carat diamonds was flat, and RAPI for 0.50-carat diamonds rose 0.8 percent. RAPI for 3-carat diamonds increased 0.4 percent during the month.
