NEW YORK – Following on the heels of Christie's blockbuster $118 million jewelry auction in Hong Kong earlier this week and establishing a new record for the most valuable jewelry auction ever held in Asia, Christie's is pleased to announce highlights of its upcoming sale of Important Jewels on June 16 in New York. This annual pre-summer event caps the spring season of Christie’s worldwide jewelry auctions and features over 200 lots, including a diverse array of colored and colorless diamonds, rare gemstones, and signed designer jewels. Estimates range from $8,000 up to $5 million, and the total sale is expected to achieve $18 million.

From modest beginnings in 1946 in Detroit, Michigan, Mrs. Margaret Adderley Kelly(pictured left), her husband, the late William R. Kelly and their son, Mr. Terence E. Adderley, shaped Kelly Services, Inc. into a Fortune 500 company that now employs over 550,000 people globally. The iconic “Kelly Girl” became a household name by 1957, synonymous with high-quality temporary employees. Philanthropy was a cornerstone of her life and many organizations benefitted from her immense generosity. In addition, jewels and fine gemstones were one of Mrs. Kelly’s greatest passions that she collected with the discerning eye of a great connoisseur. The breadth of the collection was a testament to her love for the exceptional, rare, and beautiful. On June 16, Christie’s is proud to offer The Magnificent Jewels of Margaret Adderley Kelly, highlights of which include an Art Deco diamond pendant necklace suspending a D-color, Internally Flawless diamond of 16.24 carats and The Kelly Sapphire: a Kashmir sapphire of 21.71 carats, by Cartier
