Therefore the results of each auction are not always directly comparable. Sean Gilbertson, CEO of Gemfields, commented: “Given the difficulties experienced by the Indian gemstone sector this year, the strong results from this auction underscore the enduring vigour of consumer demand for responsibly sourced Zambian emeralds and the accelerated recovery that this demand facilitates. While the Indian emerald trade is not out of the woods yet, we take significant comfort from these Lusaka auction results. We thank the very hardworking Gemfields and Kagem teams, our customers and our partners in Kagem, the Industrial Development Corporation of Zambia and look forward to furthering the Zambian emerald sector’s prominence internationally”.
