Rapaport Research says the diamond markets quieted a little in July and there was some price resistence from buyers, but overall the RapNet Composite Index increased by 0.2 percent in July.

Data also showed remarkable growth for Zimbabwe...is there no wonder where $340 million worth of Marange rough diamonds ended up?
