Moussaieff

This diamond is indeed red in color, but it also comes with a price tag that is quoted as being anywhere between $7 million and $20 million. It may only be 5.11 carats, but it is classed as being the biggest diamond of this color ever to have been classified by the GIA and this alone is enough to push the price up resulting in it costing those millions. You have to admit that it does look rather cool.
