Earth's rarest blue-green diamond could fetch 9.4 MILLION at auction

"Dubbed the 'Ocean Dream', the diamond was discovered in its rough form in Central Africa in 2002. The original crystal weighed a whopping 11.17 carats, before it was cut down to preserve and maximise its stunning colour. The final gem now weighs 5.50 carats, making it the largest diamond of this colour ever recorded."

"The Ocean Dream is categorised as a 'fancy vivid blue-green diamond' by the Gemological Institute of America (GIA). This colour is a result of prolonged exposure to natural radiation deep within the Earth over millions of years, and is so uncommon that it borders on geological singularity. 'I could spot it from across the room!' said Tom Moses, Executive Vice President and Chief Research and Laboratory Officer of the GIA."

"'The Ocean Dream is, quite simply, in a category of one,' said Tobias Kormind, Managing Director of 77 Diamonds. 'This is the largest fancy vivid blue-green diamond ever certified by the GIA in its entire history. 'There is no other diamond of comparable colour and size anywhere on record. 'It is a perfect blend of two of the rarest diamond colours to exist.'"

"While the original rough form weighed 11.17 carats, the diamond was cut down into a triangular brilliant-cut, which shifts between blue and green depending on the light. In 2003 - one year after its discovery - the diamond was one of seven exhibited at the Smithsonian Museum in Washington DC. D. Jeffrey Post, curator of the National Gem Collection at the Smithsonian Natural History Museum, said: 'The Ocean Dream was one of seven rare"
