Kate Middleton Engagement RingNovember 16, 2010
Prince William and Kate Middleton formally announced their engagement today. Kate's engagement ring is Princess Diana's 18 carat blue sapphire and diamond ring, given to Diana by Prince Charles when the two became engaged in 1981.
William and Kate have dated for eight years, with much speculation from the press about when, not if, they would become engaged. William is said to have proposed to Kate during a trip to Kenya. Watch for a Royal wedding in the spring or summer of 2011.

Since this was originally Diana's engagement ring, it's already been copied, but watch for even more look-alikes, either with faux "jewels" or the real deal.
