When Jean-Baptiste Tavernier, the explorer and merchant, sold the French Blue to King Louis XIV in 1668, thus began the world's fascination with blue diamonds.  The Hope Diamond, the most famous diamond in the world, is long believed to have been cut from the Sun King's blue gem and its legendary history has drawn millions of people to the Smithsonian Institution every year since 1958.  In 2000, to celebrate the arrival of the new millennium, a spectacular collection of De Beers Millennium blue diamonds was exhibited at London's Millennium Dome, shining international attention on one of the earth's rarest natural creations.

Historically blue diamonds were recovered in India and Brazil, but today blue diamonds are primarily mined in South Africa.  Their production is limited compared to pink and yellow stones, as the conditions required to form a blue diamond hardly ever occur in nature.  Blue diamonds are free from nitrogen, the most abundant element in the atmosphere, and they owe their color to contact with the element boron during formation.  The resulting color may range from a pale blue to a dark blue, many with secondary tones of grey.  The rarest of the blue diamond grades is fancy vivid blue, a deeper intense blue which balances the tone and saturation of color.  The scarce availability of fancy vivid blue diamonds has propelled them to the forefront of the world's most coveted colored diamonds and their occasional appearance at auction is an exceptional opportunity for collectors mesmerized by the beauty and brilliance of this miracle of nature.
