De Beers group produced 31.2 million carats of rough diamonds, increasing production by 12% compared to the previous year, when 27.9 million carats were mined.
The largest shareholder of the diamond-mining company, Anglo-American, said that diamond production growth was recorded in all regions of De Beers activity and was particularly noticeable in Botswana and Canada.
De Beers sales for the year increased to $ 6.4 billion compared to $ 6.1 billion in 2012.
According to the report, the weakening of prices for diamonds, large volumes of commodity stocks in the centers of diamond cutting and liquidity problems leveled the price increase in the first half of the year.
However, this decline in prices, accompanied by an increase in sales of diamonds, led to the stabilization of the diamond market, the situation at which it began to improve by the end of the year.
The diamond price index of De Beers has grown by 2% since the beginning of the year, while the average prices for rough diamonds increased by 5% due to a change in the assortment of boxes.
"Despite the uncertain global economic environment, sales of diamond jewelry in terms of local currency showed growth in all major consumer markets, except in India, where the difficult economic situation and the devaluation of the rupee led to a drop in demand," said De Beers CEO Philippe Mélier (Philippe Mellier) during a teleconference.
According to him, the gradual increase in forecasts of world economic growth will provide a slight strengthening of the growth in demand for diamond jewelry in 2014.
