555 carat diamond
Checking the internet easily reveals that the story about this 555-55 diamond has been fabricated. Materialscientist (talk) 09:33, 22 October 2009 (UTC)

and what about this?

 * I know, but it is a fake or a joke created in 2004-2005 and picked up by a few cites around then. No reliable sources confirm that. I was going to write about it, but quickly found it is a hoax, which is not even masked (555-55 numbers, black, etc, details speak for themselves).

OK i will check this with my client that has the stone... Ran Gorenstein himself, if it's true what you say then indeed this is a joke!

I checked with my client the story about 'largest cutted diamond 555.55 carat'... and it's a true story! I have here in my hands the certificate from GIA (Gem Trade Laboratory)

So how to add the item 'Largest Cutted Diamond in the World' back into Wikipedia?
 * Difficult situation. Wikipedia facts are to be confirmed by reliable references, thus if the certificate is the only source, you can consider scanning it and posting on WP. This is the last resort though - WP does not wish to evaluate primary sources and prefers a specialist to evaluate those and write about that ("secondary source"). Regards.
