When William, Duke of Cambridge, proposed to his girlfriend Kate Middleton in 2010, he didn't offer just any ring to her: It was the worldwide known, famous sapphire ring that once belonged to his mother Lady Diana.

The impressive ring with an oval-cut, 12-carat sapphire, which is adorned with 14 diamonds, already become famous in the 1980s when Prince Charles and Diana sealed their engagement with it.

Back then, the ring caused a scandal because it stemmed from a jeweler's pre-made collection, meaning that it would have been purchasable for anyone.
