With global diamond demand forecast to grow at approx 3.5% annually over next five years, a supply gap down the line seems inevitable if forecasts hold.
Independent diamond industry analyst and consultant Paul Zimnisky has published a report on global rough diamond prices in the 10 years since the global financial crisis.
From February 15th to March 13th, a market-cap weighted aggregation of diamond miners in U.S. dollars including ALROSA Joint-Stock Company, Petra Diamonds Ltd, Dominion Diamond Corp, Gem Diamonds Ltd, Lucara Diamond Corp, Stornoway Diamond Corp, Firestone Diamonds Plc, and Mountain Province Diamonds Inc, was down 14.3%.
