The 31.06 carat, rare grey-blue Wittelsbach-Graff Diamond is set to make its exciting first public appearance in half a century on January 28, 2010. The spectacular diamond was last displayed in 1958 at the Brussels precious gemstone exhibition. The National Museum of Natural History announced that it would add the blue diamond to its precious gemstone exhibition, which already includes the famed Hope Diamond. The two rare blue fancy colored diamonds will both be displayed in the same gallery so as to allow visitor’s the opportunity to compare and contrast between the two gemstones.
Last week, Christie's auction house held its annual "Magnificent Jewels from a Distinguished Private Collector", listing among other famous gems, the stunning "Evening Star" diamond.
Expert gemologists have recently discovered that the world’s two most famous fancy colored natural blue diamonds, thought to be part of the same mother stone, are not related after all.
