A rare 18th century 300-carat diamond with links to Marie Antoinette is going up for auction
The historic piece, which was owned by the highest ranking of aristocracy and worn during at least two royal coronations, is part of auction chain Sotheby's 'Royal and Noble' sale in Geneva this November.
Ai-Da, a humanoid robot artist, has made history by selling her painting of Alan Turing, titled A.I. God, for $1.32 million (€1.225 million) at Sotheby’s Digital Art Sale.
