What Affects Diamond Prices?

The average increase in value of rough diamonds is about 3% per year. Most important driving forces are the overall economic performance as well as internal changes in the diamond industry. Empirically rough diamond prices recover fast after crises. After the last financial crisis the big players in the market like De Beers acted quickly and cut production. As a result gobal production fell from 175 million carats in 2006 carats to only 120 million carats in 2009.

Similar to crises the market reacts quickly to the discovery and exploitation of new diamond mines. In the mid 1980s Russian and Australian mines started production which caused prices to drop. Also, the large-scale sale of De Beers huge diamond stock beginning in 2002 pressured prices. But there are other solutions to cutting production: Shortly after the crisis of 2007 the Russian diamond producer ALROSA did not reduce its production but instead sold the oversupply to the state-run mineral resources fund "Gokhran". By doing so Gokhran build up the largest diamond stock worldwide. More important for price developments than large stock are macroeconomic changes because they affect the demand side on a much larger scale.

After losing its monopoly De Beers a number of smaller companies own a smaller proportion in relation to the entire market and influence the market price less. The structure of the diamond market is important: Smaller market actors need to keep stock piles smaller due to additional costs that comes with them. At the end of the day every supplier will be willing to sell diamonds on a discount when he needs liquidity. This is especially true for the market of polished diamonds as profit margins tend to be very small here.
