Blue diamonds are considered a major trophy in any connoisseur’s collection.
There are also naturally occurring blue diamonds, however, they’re extremely rare. Blue diamond jewelry created purely by nature, can cost several hundred thousand dollars or more. Treated blue diamonds, however, will cost significantly less and is a popular and unique option to a regular white diamond — and they can cost less than white diamonds also, at around half the cost, for a quality colored diamond piece. Can cost less because you don’t need to begin with an absolutely white diamond as you’re going to be treating it to alter the color to blue. A fancy colored diamond manufacturer, will begin with a yellowish or low color class diamond and treat it blue, so costing less than a high-end white diamond.
Natural blue diamonds are so rare that most jewellers have never even seen one.
They include such stones as the Queen of Holland, the Blue Empress, and the Regent Diamond. The most celebrated blue diamond is the “Hope” diamond in Washington ‘s Smithsonian Institute. Its last owner was New York jeweller Harry Winston. He bought it to donate to the Smithsonian and only possessed it for twenty-four hours. Whilst his insurance firm and armed couriers were talking over the price and technique of delivering the priceless gemstone to Washington, Harry sauntered down to the post office and mailed the diamond in a cigarette packet as ordinary post.
They are exceptionally rare and exceptionally beautiful, and their value indicates no signs of subsiding in the predictable future. Less than two hundred flawless, colorless diamonds over five carats are recovered each year. Far less colored diamonds are discovered per year, making them a highly treasured commodity.
It is extremely unlikely that sizeable new caches of natural diamonds will be retrieved outside of recognised diamond mines, so there won’t be market flooding in the future. The value of high-grade diamonds has been recognised to gain by as much as fifty percent in one year.
Blue diamonds are mined in South Africa, India and Australia. Boron atoms, even in smaller concentrations, cause blue color. Some rare gray – blues are caused by hydrogen. The secondary hues and modifiers are: gray, green and violet. The elements of boron may also be substituted within a diamond during its formation. Boron absorbs red light, hence in the absence of nitrogen, diamonds containing boron are blue in color. Diamonds containing boron also exhibit unusual electrical properties and are semi-conductive in nature. Hydrogen is another impurity that, in high quantities, can cause grey or blue coloring in diamonds.
In fact, blue is the second rarest natural diamond color, down just below the rareness of natural red diamonds. They range in shade from the crystal blue of a winter sky to the intense gray-blue of an angry ocean, and lend themselves nicely to both yellow gold and silver or platinum settings.
When buying a blue diamond, dull looking or cloudy stones should be avoided the darker the colour blue, the better quality.And remember that most blue diamonds obtainable in the market now are man made.
Blue diamonds are used in the creating necklaces, rings, ear rings and bracelets.
