Ocen Dream Diamond

Found in the Central Africa, the Ocean Dream diamond is a magnificent stone weighing around 5.51 carats. The color of this gem is so unusual that many gemologists thought that it was synthetically colored in the laboratory. Till date, no diamond has been found of this color and shape. The facts given by the Gemological Institute of America, the unique color of this famous Ocean Dream diamond was formed due to the flaws in the atomic structure of the stone. The gem’s blue- green exotic color combination was the result of the earth’s radiation making defects in the stone’s atomic structure and giving rise to this color. This amazing diamond was exposed to radiation for many years and this ultimately resulted in the unusual fancy hue. Scientific investigations have revealed that that this type of color and size is rarest among the rare diamonds. In the year 2003, the rare Ocean Dream diamond had been displayed in the collections of the “The Splendor of Diamonds" held in the Smithsonian Museum, Washington.This precious stone was placed with the other magnificent unique diamonds of the world like De Beers Millennium Star, Moussaieff Red, and The Heart of Eternity.
