What is a Blue Diamond
On the rarity scale of natural colored diamonds, the blue diamond is next only to red (or pink) and orange diamonds and probably share this second place with green diamonds.
Collectors of colored diamonds consider Natural fancy blue diamonds as a must have item in their collection.
The color in gray-blue, grayish blue, blackish blue or black-blue colored diamonds is caused by the presence of minor amounts of boron in their crystalline structure.
Green-blue or greenish blue – teal – colored diamonds usually contain nitrogen impurities in aggregate form.
Blue diamonds come in different intensities: Light Blue, Fancy Light Blue, Fancy Blue, Fancy Dark Blue, Fancy Deep Blue and Fancy Vivid Blue. They range in color from the blue of the sky to a more “steely” colour than sapphire.
Natural blue diamonds are so rare that even professional jewelers don’t get to see one in their lifetime. An estimated ten thousand white diamonds are produced by mother earth for a single colored diamond of any color.
Natural blue diamonds are mined in Australia and South Africa, and along with the ‘red’ diamonds are the most rare and valuable of the colored diamonds. A natural blue diamond can cost as much as $100,000 to $250,000 per carat, depending on clarity, color, and size.
Most of the beautiful blue diamonds on sale today, are naturally yellow diamonds whose color has been enhanced with artificial irradiation. The treatment can only work with a small minority of diamonds, & involves irradiating them causing the color to change, usually followed by heat treatment to stabilize the induced color.
Other factors (such as cut, clarity and carat weight) remaining the same, fancy blue diamonds are more expensive than ordinary near-colorless ones. Their processing further adds to the costs, so only diamonds of high clarity are chosen for treatment. The diamonds that are selected, start off with less desirable colors like brown or yellow. The final color that any particular stone will take on after treatment cannot be predicted.
The blue diamond can be cut into almost any shape and come in the Round Brilliant, Heart Shape, Pear Shape, Princess Cut, Marquise or Navette Cut.
The color of the Blue Diamond symbolizes stability, trust, loyalty and wisdom. Blue is the color of the sea and sky.
The Hope Diamond is the world’s largest and most famous deep blue diamond, with a cut weight of 45.52 carats. Formed deep within the core of the Earth more than a billion years ago, it was carried to the surface by a diamond bearing volcanic duct in Golconda, India.
Golconda was once renowned for the diamonds found on the south-east at Kollur Mine near Kollur (modern day Guntur district), Paritala (modern day Krishna district) and cut in the city during the Kakatiya reign.
Many famed diamonds are believed to have been excavated from the mines of Golkonda, such as:
• Darya-e Nur
• Nur-Ul-Ain Diamond
• The Koh-i-noor
• The Hope Diamond
• The Regent Diamond
• Wittelsbach Diamond
Since its discovery in the early 1600s, the hope diamond has gone across oceans and continents, and passed through the hands of kings and commoners. It has an infamous past, having been sold, stolen, recovered and re-cut from the French Blue diamond once in possession of the French Royal Treasury.
The diamond acquires its name from Henry Philip Hope, who added the blue diamond to his collection sometime between the death of King George IV in 1830, and 1839. In 1958, Harry Winston, Inc. donated the Diamond to the Smithsonian Institution, where it remains a compelling showpiece of the National Museum of Natural History.
It has been described as the “most famous diamond in the world” and, after the Mona Lisa, it is the second most-visited artwork in the world.
