Kate Middleton's engagement ring


The world's most famous family heirloom

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 1980ies 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.

Despite it is not a bespoke piece of jewelry, the ring Kate Middleton is wearing on her finger today is one of the most copied rings worldwide.
