TORONTO, Dec 9 (Reuters) - Harry Winston Diamond HW.TO reported flat quarterly results on Wednesday as the temporary shutdown of a diamond mine and decreased demand for expensive jewelry weighed on the Canadian miner's results.
Harry Winston, which owns a minority stake in the Diavik diamond mine in Canada's Arctic and operates a string of high-end jewelry shops, lost $214,000, or nil a share, in the third quarter, ended Oct 31, compared with $71.9 million, or $1.17 a share, for the same time last year.
Sales were halved to $74.8 million from $148.6 million, due to a steep decline in the volume of carats sold and a mild decrease in rough diamond prices.
Production was hindered by the planned temporary closure of its Diavik diamond mine in the Northwest Territories.
