The "Beau Sancy", one of the oldest and most famous diamonds in the world that is in private hands, will be auctioned by Sotheby's and could reach a price of $ 4 million.
Whoever does not have the money to buy the glittering pear-shaped gem of almost 400 years old and 34.98 carats, you can see it on exhibit in Paris and then London and Zurich before it is auctioned in Geneva on May 14.
Diamond "has a fascinating story and it really is a sale that happens only once in life," said David Bennett, head of jewelry at Sotheby's.
"When it was created in the sixteenth century, it was new, bold, and so became the most sought jewel of its time. Before Beau Sancy, all diamonds were rudimentary."
Such was the fame of the diamond in 1604 that the French king Henri IV bought as its first owner. It was then called Baron de Sancy and Henri presented this as a gift for his elegant wife Marie de Medici, one of the richest women in Europe.
After the assassination of the king, she fell into poverty and had to sell the jewelry, which cut the famous gem mines of the Indian city of Golconda.
Over time, the diamond passed through four European royal families, including the House of Orange in England. Its most recent owners are the descendants of the last emperor of Germany.
