London, Nov 3 : A rare blue-grey diamond, which traces its history to India, and had been given to the girl in one of the most famous paintings in Western art, will soon go under the hammer at Christie’s, London.
The Wittelsbach diamond, which apparently originated from the Indian diamond mines, is almost once inch in width.
A Christie’s spokesperson claimed that offering a blue diamond of this type was ''truly extraordinary''.
It was given to Infanta Margarita Teresa by her father King Philip IV of Spain on her engagement to her uncle Leopold I of Austria—one of the most historic events in European history.
