4.Wittelsbach-Graff Diamond – Price:$24.3 million
This diamond has survived over three centuries!
The Wittelsbach-Graff Diamond is one of the oldest colored diamonds in the world and was discovered all the way back in the mid-17th century in India.
When it was first found the diamond weighed 35 karats, but after hundreds of years passing by and after being part of the Austrian and Bavarian crown jewels, the diamond weighs now about 30-31 karats.
And of course, the time left some marks on it, so the gem was chipped around the edges, but the English jeweler Lawrence Graff took care of refashioning it.
This Fancy Deep Blue beauty is worth $24.3 million!
