The Graff Blue
Not to be confused with the Graff Imperial Blue, which I am still looking for
a photo of. I was not able to find many details about this stone, other than its
weight, which is 6.19 carats. If Graff ever goes into more detail about their
unusual stones, I'll post more about this one. Judging from this photo, and the
fact the company is Graff, the stone is probably not irradiated, and is at least
a VS1 in clarity.
This
photo is from the auction catalogue for Christie's May 1st, 2000 auction in
Hong
Kong. I doubt the stone actually sold, since the Graff website still
features the piece.
Natural blue diamonds command some of the highest prices in the
world of gemstones. The more intense the blue color, the higher the price.
Natural blue diamonds like the Wittelsbach,the
Transvaal
Blue, the Sultan of
Morocco and of course the Hope are extremely
rare gems.
