Those beautiful, bottle-green, evenly colored, well-cut emeralds from Zambia are soon to be in short supply. Gemfields chief executive Ian Harebottle, is determined to make Zambian rough a premium brand over next couple of years, stating that “The demand for emerald has been increasing by 20 percent. Our mines are making up for about 20 percent of the global supply of emeralds. Twenty times rarer than diamonds, emeralds will be slated as both sexier and funkier, just like Apple products. Gemfields owns Kagem mine in Zambia which is spread across 45 square kilometers and presently contributes 15 percent of the world’s total production of emeralds. The other emerald producing countries are Colombia, Brazil, Afghanistan and Pakistan.
