The world’s largest diamond producer reported its latest rough diamond sales at a provisional $575m. This is a 6% increase from the $541m in 2017. Healthy demand from China’s retail jewellery market is the driver, the world’s second-largest diamond market.
Analysts estimated lab-grown diamonds could soon account for as much as 8% of the polished diamond market by weight, but less by value. De Beers has announced it would set up synthetic diamond production.
