Hope and Wittelsbach-Graff diamonds are not from same stone


According to a group of scientists led by Jeffrey Post, curator of the National Gem Collection at the Smithsonian Institution, The famed Hope Diamond and its chief rival, the Wittelsbach-Graff Diamond, were not cut from the same stone. The Hope is 45.52 carats and the Wittelsbach-Graff Diamond is 31.06 carats.

They were some speculation over the past decades that Hope diamond and the Wittelsbach-Graff Diamond are from the same origin. The speculations were that this two famous and valuable diamonds are cut from the same rough diamond.

The speculations were based on the fact that both diamonds, Hope diamond and the Wittelsbach-Graff Diamond have the same physical conditions, same color and clarity, but not the same pattern.

Scientists who were examining this two diamonds are leave the posibility that both of them are originating from the same diamond field but definitely not form the same stone.

With more than 50 years out of the display, Wittelsbach-Graff diamond is the most famous diamond people have never seen. The last time Wittelsbach-Graff diamond was on the public display in 1958.
