You’re an unusual woman, why not opt for an unusual ring? While diamond rings are common enough, beautiful blue diamond rings are definitely out of the ordinary. Learn more about this special gem and decide whether it’s for you.
While white and off-white diamonds are the best known, diamonds are found in nature in a rainbow of colors, including brown, lavender, green, yellow, red, pink, black and blue. These colored diamonds are called fancy diamonds. While some colored diamonds – some of the yellows, for instance – are worth less than white diamonds of comparable quality, others are worth more, due to their rarity. Blue diamonds are some of the rarest, and therefore good quality blue diamond rings can be quite valuable.
Why the Diamonds are Blue
The blue color of the diamonds are due to impurities, specifically boron. While the diamond is forming, boron gas is trapped in the crystal structure, creating a diamond with an arresting blue color.
Shades of Blue Diamond Rings
Most blue diamonds are a pale or light blue, but some have a deeper blue color, though not so deep as a sapphire. Generally, for two diamonds of similar size and quality, the deeper the color, the more valuable the diamond.
Synthetic vs Natural Blue Diamond Rings
The prevalence of synthetic diamonds had brought the price of blue diamond rings into reach for some who might not have been able to afford them before. While synthetic blue diamonds appear quite similar to natural blue diamonds to the naked eye, under ultraviolet examination a good jeweler can easily tell them apart.
White Diamonds with Blue Fluorescence
Some jewelers might try to use the fact that blue diamond rings are so costly to make a little extra money off a white diamond with blue fluorescence. In a white diamond, the blue fluorescence should make it less expensive, not more.
The Hope Diamond
Perhaps the most famous blue diamond is the Hope Diamond, a 45 carat stone that is currently displayed at the Smithsonian Museum in Washington D.C. Its deep blue color and large size make it one of the rarest diamonds ever found. Historians believe that the Hope Diamond was first unearthed in Indian during the 1600s. The Frenchman Jean-Baptiste Tavernier obtained the uncut stone and carried it back to France, where it was cut into a 115-carat diamond known as The Tavernier Diamond, which he sold to King Louis XIV. The stone was recut to a 67 carat diamond known the Blue Diamond of the French Crown, or the French Blue. After the King and Queen were killed during the French Revolution, the stone disappeared for decades, reemerging as the 45 carat Hope Diamond. While it was long suspected, researchers have recently verified that the Hope Diamond was in fact cut from the French Blue. The stone spent some time in England before traveling to the United States and finding its way into the collection of the Smithsonian when famed American jeweler Harry Winston donated it.
Russian Blue Diamond
I once read an account of a wealthy Russian Émigré who had been given a valuable jewel in a convent by one of the Grand Duchesses before escaping the Bolsheviks. For years she believed it to be a large sapphire, only to discover much later that it was actually a much rarer blue diamond.
