The Ocean Dream is a diamond measuring 5.51 carats (1.102 g), rated in color as Fancy Deep Blue-Green by the Gemological Institute of America. The Ocean Dream is the only natural diamond known to the GIA to possess a blue-green hue, making it one of the rarest diamonds in the world. (A blue-green colour is commonly seen in artificially enhanced diamonds, whose colour is imparted by various irradiation methods.) After careful study, the GIA concluded that its distinct hue is a result of millions of years of exposure to natural radiation. The Ocean Dream originated in Central Africa, and is currently owned by the Cora Diamond Corporation.

The Ocean Dream was displayed as part of the Smithsonian's "The Splendor of Diamonds" exhibit, alongside the De Beers Millennium Star, The Heart of Eternity and the Moussaieff Red.
