Christie's faces backlash over sale of Nazi-linked jewelry collection.

Christie's is facing criticism for auctioning off jewelry from the collection of the late Heidi Horten, whose husband, Helmut Horten, built his fortune by purchasing businesses from German Jews who were forced to sell during World War II. The collection, which includes a sapphire and diamond necklace with an estimated sale price of $1.5 million, is expected to gross $150 million. While none of the jewels were looted during the war, the origins of the Horten fortune have raised ethical concerns. All proceeds from the sale will be directed to a foundation that supports philanthropic causes.
