Lot Essay
Born in Helena, Montana in 1896, Margaret Thompson Biddle was the daughter of notable copper miner and financier, William Boyce Thompson.
Mr. Thompson was born and raised around mining in Montana, so it was no surprise that he went on to make a name for himself in the copper mining industry. He attended the prestigious Philips Exeter Academy in New Hampshire, and Columbia University. After retiring from the New York Stock Exchange around 1915, Thompson’s interests returned back to mining where he founded the Newmont Mining Corporation. Generously supporting many philanthropies and efforts around the world, he was awarded an honorary title of Colonel by the American Red Cross. In addition to the several companies he owned, Thompson founded the Boyce Thompson Institute in New York in the 1920s. The institute focuses on plant research with the goal of improving human welfare.
Margaret Thompson married Anthony Drexel Biddle Jr. in 1931. That year he was also appointed the Minister to Norway by President Roosevelt, and then Ambassador to Poland 1937. This role led Anthony, Margaret and their family all over the world. After fleeing Poland in 1939, they landed in England for one of Anthony’s commissions. In this position, he worked with the governments-in-exile of Belgium, Czechoslovakia, Luxembourg, the Netherlands, Norway, Poland and Yugoslavia. Biddle held numerous ambassador positions in the years that followed before re-enlisting in the army in 1944.
Margaret relocated to France after she and Anthony separated at the end of World War II. She had a home on the French Riviera, and a spectacular hotel particulier on the notable boulevard St. Germain in Paris. Not only was she a writer and author of The Women of England, Margaret was also known to be quite the hostess and socialite. One could find the Eisenhowers, the Duke and Duchess of Windsor, and many other notable French creatives at her soirees. In addition to having a wonderful jewelry collection, Margaret was an avid collector of fine porcelain, silver, home furnishings and art by the most distinguished artists and makers.
In December of 2022, Christie's was thrilled to offer Mrs. Biddle’s diamond ‘Palm Tree’ brooch mounted by Cartier in the Magnificent Jewels Auction. The brooch features a round diamond of 13.30 carats that was part of Mrs. Biddle’s jewelry collection. Seen in the elegant photo of Biddle captured by the imitable Horst P.

Charming in shape and captivating in size, the diamond is now accented by a later made platinum mounting. Christie's is delighted to offer this incredible diamond (Lot 91) that exudes the utmost elegance just as its previous owner once did.
