London, Oct 13 (ANI): Jennifer Aniston's giant diamond engagement ring has been put to shame by the four-hundred-year-old Archduke Joseph diamond, which is expected to sell for 15 million dollars at an auction on November 13 in Geneva.
The colourless stone is almost ten times heavier than the 43-year-old actress' new rock, which is believed to weigh eight carats.
Describing the star lot, Christie's head of jewellery, Rahul Kadakia, said, "It can be hard to visualize exactly how big a 76.02 carat diamond is."
"It's about the size of a quail's egg, and completely pure and clear in color," the Daily Mail quoted him as telling Today magazine.
Although it has an estimate of 15 million dollars, experts believe that the diamond will fetch a lot more, attracting buyers from the Middle East, Asia and Russia.
"15 million dollars is a very fair estimate and we do hope that we will achieve a new record price," he said.
"If it does go on to make more than 15 million dollars, that is quite a return on investment. In what other type of asset could you expect that kind of return over 19 years?" he added. (ANI)
