A MAGNIFICENT UNMOUNTED RECTANGULAR-CUT FANCY BLUE DIAMOND
Weighing 19.20 carats
With certificate 8405959 dated 22/12/1993 from the Gemological
Institute of America stating that the diamond is fancy blue, natural
colour, VS1
Since the sale of a 6.19-carat blue diamond at Christie's Geneva in 1990 earned the world record price per carat of $500,000, coloured diamonds have gained increasing international recognition and become highly desirous among serious collectors. This superb rectangular-cut fancy blue diamond, the third largest of this shape ever to be offered at auction, should be no exception. Its fine cut and beautiful colour place it unquestionably in the category of great blue diamonds.
Throughout auction history, blue diamonds have been coveted by conoisseurs whether one thinks of the high degree of interest generated by Christie's offering of the mysterious Wittelsbach diamond in the Bavarian Crown Jewels sale of November 1931 or the later appearance in May 1983, at Christie's Geneva of the Marie-Antoinette blue diamond, a gift to the famous queen on the occasion of her marriage to the future King Louis XVI. Initially discovered in the Golconda region of India, blue diamonds were consequently imported to the courts of Europe by renowned travellers such as Jean-Baptiste Tavernier. Their colour derives from small quantities of the element boron which entered into the crystal structure at the moment of formation hundreds of millions of years ago. Belonging to the rare Type IIb category, they are also capable of conducting electricity.
