RAPAPORT... PRESS RELEASE, September 8, 2015, New York … Diamond prices softened in August and sentiment weakened as the slump in financial markets is expected to reduce discretionary spending. Dealer trading was quiet with Belgium closed for vacation and liquidity tight in India. Cash buyers in New York and Israel are looking for good deals, waiting for lower prices and filling specific orders. No one is buying for inventory.

The RapNet Diamond Index (RAPI™) for 1-carat laboratory-graded diamonds fell 0.9 percent during August. RAPI for 0.30-carat diamonds declined 1.7 percent, while RAPI for 0.50-carat diamonds dropped 1.9 percent. RAPI for 3-carat diamonds slipped 1.5 percent during the month.

RAPI for 1-carat diamonds fell 3.7 percent during the first eight months of the year and was down by 12.9 percent from one year ago on September 1.

According to the Rapaport Monthly Report – September 2015, diamond jewelry demand is lagging as China’s economic growth slows. The recent stock market plunge and yuan currency devaluation has reduced consumer wealth ahead of the October Golden Week holiday. U.S. consumer confidence has also softened amid financial market volatility. Expectations are low for the September Hong Kong show as Far East demand is specific and inventory levels remain high.

Diamond manufacturers are maintaining low polished production levels and rough demand remains weak. Manufacturers continue to refuse high-priced rough diamonds despite an estimated 10 percent cut in De Beers prices in August. While rough production is projected to rise in 2015, mining companies have reduced supply and prefer to raise their inventory levels rather than significantly lower prices.

“Rough prices are still too high and manufacturers are unprofitable. Rough prices should drop an additional 20 percent in order to enable reasonable profit for manufacturers and dealers,” said Martin Rapaport, Chairman of the Rapaport Group.
