The Ocean Dream diamond
The Ocean Dream diamond is a natural diamond with an unusual and fancy deep blue green color just as the color of the ocean. This is a trust worthy information given by Gemological Institute of America that its distinct hue is a result of millions of years of exposure to natural radiation or due to the flaws in the atomic structure of the stone.
It is a one of the rarest diamond which weighs 5.51 carats enriched with rich blue – green hue.
The Ocean Dream diamond originated in Central Africa, and is currently owned by the Cora Diamond Corporation.
For the very first time, 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 along with other various rich and rare diamonds.
Its color is so distinct that that many gemologists thought that it was synthetically colored in the laboratory and the most distinguished factor about Ocean American diamond is that no diamond has been found of this color and shape, till date.
The Cullinan Diamond
The Cullinan Diamond
The Cullinan diamond is the largest rough gem-quality pear shaped diamond ever found with a weight of 3,106.75 carats. It color is white crystal like glass.
The credit of the discovery of Cullinan Diamond goes to Frederick Wells, surface manager of the Premier Diamond Mining Company in Cullinan, which was excavated on January 26, 1905.
Frederick Wells was walking through the mine when he discovered the Cullinan diamond which looked like a big piece of glass, as being embedded in one side of the mine wall.
An amount of $10,000 was rewarded to him for his discovery. This stone was named after Sir Thomas Cullinan, the owner of the diamond mine.
After its discovery, this precious diamond was purchased for $800,000 as a souvenir for King Edward VII for the occasion of his 66th birthday.
Cullinan is now mounted in the head of the Scepter with the Cross.
The special touch about this diamond is that it is renowned as the largest cut diamond was cut into three large parts by Asscher Brothers of Amsterdam, and eventually into 9 large gem-quality stones and a number of smaller fragments.
The Hope Diamond
The Hope Diamond is a large superfine deep-blue diamond which weighs 45.52 carats, housed in the Smithsonian Natural History Museum in Washington, D.C.
It is believed to have been excavated from the Kollur mine in Golconda, India. Gemological Institute of America describes its color as “fancy dark greyish-blue.” It refuses to highlight its name, as the diamond is believed to bestow a curse to its owners.
A distinct feature about this stone is that it exhibits an unusually intense and strongly-colored type of luminescence which after exposure to short-wave ultraviolet light, the diamond produces a brilliant red glow-in-the-dark effect that persists for some time after the light source has been switched off.
The Hope Diamond is blue to the naked eye because of trace amounts of boron within its crystal structure. Its estimated value is $300–$350 million USD £150-£175 million GBP. It got its name in 1830 after the king Henry Philip Hope of London.
The Earth Star Diamond
The Earth Star Diamond was found on May 16, 1967 at South African mine of De Beers, the Jagersfontein Mine.
The name of the diamond seems to have been inspired by two of the unique characters of the stone, viz. the strong brown color, and its extraordinary brilliance, which led the owner of the diamond, Mr. Joseph Baumgold, of New York, to name it the “Earth Star”.
The emergence of Earth Star diamond came from the 2,500-foot level of the volcanic diamond-bearing pipe.
The rough gem weighed 248.9 carats and was cut into a 111.59 carats pear-shaped gem with a strong brown color and extraordinary brilliance.
The diamond was bought in 1983 for $900,000.
The diamond was found to have a greater degree of brilliance than is usually seen in a gem of such a strong color.
The combination of color and brilliance forced Joseph Baum gold to name it as the Earth Star.
