A stunner in every way, the gem meets the criterion for a near-perfect stone. The sophistication of the stone is reserved for the finest diamonds, evocative of important stones found in the fabled mines of India's Golcondo region and several other mines in Brazil and South Africa.

The gem has perfect symmetry with a cut so precise it can stand totally balanced on its pointed end or cutlet. In addition, the diamond has no traces of colorant nitrogen, the feature that gives the stone such transparency and sparkle. Only 2% of all diamonds need this chemical.

"The old-world charm of this beautiful gem, along with a softness to its cut and its superb brilliance, ranks it among some of the most wonderful diamonds to have appeared for sale at Christie's, such as the historical Polar Star, to [which] it bears a striking resemblance," said Rahul Kadakia, head of Jewelry Americas at Christie's.

The Polar Star diamond is one of the famous diamonds in the world, having been owned by Russian royalty until its sale to the House of Cartier in the 1920s, and later on selling at Christie's Geneva in 1980 for $5.1 million, a huge sum at the time.

Scientists at the University of Ulm in Germany have found that diamonds may have been an important factor in the early period of life on Earth. In research they found that when treated with hydrogen, natural diamonds formed crystalline layers of water on the surface. These crystalline layers are an important requirement for life.

Diamonds, which are crystallized carbon, predate the oldest known living on this planet. Scientists posit that in prehistoric times, when molecules landed on the surface of hydrogenated diamonds several billion years ago, the result may have led to more complex organic molecules that ultimately gave rise to life.

The researchers said that hydrogenated diamonds transform into the best possible platform for the source of life. They also found that the diamonds had electrical conductivity that could have started the chemical reactions required to generate life.
