From Switzerland to Hong Kong, Christie's Magnificent Jewels auctions have had a merry month of May, posting record sales of diamonds and iconic jewelry creations, with results from Hong Kong exceeding those of any Christie's jewelry sale for the past four years.
Since May is the fifth month of the year I thought it appropriate to visit five of history's most notable and valuable emerald jewels, beginning with the most expensive emerald piece ever sold at auction and finishing with, perhaps, the most historic of all time. Enjoy.
In February we announced results from the inaugural IGI JEWEL Jewelry Design Contest. We have shared the winners and finalists several at a time in prior posts. Now we are pleased to feature all 26 creations together, bringing our coverage of this uplifting event to a close.
