The 39.34 carat cushion-cut diamond is an extremely rare and fascinating stone. Graded with D color, internally flawless clarity and designated Type IIa, the stone meets steep criteria. Type IIa diamonds are rare gems of the diamond family which have no traces of the colorant nitrogen. The absence of this element, seen in 98 of diamonds, gives the stone a purity of color and degree of transparency that is observed only in the finest stones originating from the fabled mines of Golconda, Brazil and South Africa.
In addition to its color, clarity and brilliance, the cut of this stone is paramount. The finish or surface of diamonds is divided into three categories: polish, symmetry and facet survey. Polish considers any surface characteristics that arise from the finishing process. Symmetry refers to the consistency of the shape, the positioning of the facets and the overall balance of the stone. Facet survey is an overall assessment of the number of facets and general appearance of the stone. The diamond achieved an excellent/excellent rating for polish and symmetry showcasing the diamond cutters focused skill.
There is an obvious comparison between this stone and the famous Polar Star diamond. The Polar Star diamond, named for its eight-pointed star faceting arrangement, was discovered in an alluvial deposit of the Krishna River in India at the end of the 19th century. Renowned for its unsurpassed brilliance and precision cut, it is one of the most famous diamonds in history. The Polar Star passed through the hands of many illustrious owners including Joseph Bonaparte and Princess Tatiana Youssoupoff of the Russian elite. The Youssoupoff family is most remembered for their incredible jewelry collection, affiliation with the Romanovs and involvement in the murder of Rasputin. Prince Felix Youssoupoff fled from Russia during the Revolution, taking the treasured gem with him. It was eventually sold to the House of Cartier and later offered at auction at Christies Geneva in 1980.
The exquisite cut and soft shape of the 39.34 carat cushion-cut diamond is reminiscent of the Polar Star. Both stones have a limpid transparency to them, extreme brilliance and a sophistication reserved for the finest diamonds. In addition, its precise cut allows it to stand on its perfectly balanced culet just as with the Polar Star. The Polar Star was acquired by a private collector at Christie's Geneva in November 1980 amongst a spirited bidding contest and this beautiful diamond will once again give connoisseurs the opportunity to own a world class gem.
