Premier Blue: The Largest Round Fancy Vivid Blue Diamond for Sale

To help celebrate its grand 40 th anniversary event in
Asia, renowned auction house Sotheby’s is planning to
put the world’s biggest and rarest round cut diamond
under the hammer as part of the company’s
“Magnificent Jewels and Jadeite” autumn sale.
Apparently the one of a kind “fancy vivid” blue diamond
is already creating ripples among the super-rich since it
is tipped to fetch more than $19 million at the
prestigious auction that will be conducted in Hong Kong
on October 2013.
The exceptionally rare 7.59 carat precious stone is
reportedly the size of a shirt button. It is expected to set
a one of its kind worldwide sales record. The rarest of
the rare brilliant cut, internally flawless stone has been
aptly named as “Premier Blue” since it is the largest
round fancy vivid blue diamond to be ever graded by
the renowned Gemological Institute of America. The
round brilliant is the most common cut used by global
jewelry designers since it helps to maximize a
diamond’s inherent brilliance. However the high levels
of wastage incurred during the cutting process implies
that it is very rare that a coloured diamond is used.
Reportedly all the blue coloured stunning rare
diamonds receive their natural luminescence owing to
the presence of the trace element boron. However at
present very few rare diamonds display a pure natural
blue hue. It is believed that the rare diamond is to be
sourced from the Cullinan mine situated near the South
Africa city of Pretoria, a place famous for being the
world’s main provider of rare blue diamonds. Prior to
the auction, viewing of the precious stone would be
held in several locations such as London, Geneva, New
York and Doha. It has also been speculated that the
rare sale is expected to spark a friendly bidding war
among the wealthy East Asian collectors. According to
some media reports, Hong Kong has been ranked
alongside Geneva and New York as a major center for
jewelry sales for the last seven years.
