The Bvlgari Blue is a rare two-stone, diamond ring. It was sold at auction on 20th October 2010 for $15,762,500. It features a colourless diamond and a vivid fancy blue diamond, the latter being “the largest fancy vivid blue diamond of this cut ever to be offered at auction.”
The Bvlgari Blue features two “extremely precious” stones. The first is a 9.87 carat, triangular-shaped, colourless diamond. This is paired with a 10.95 carat, triangular-shaped, fancy vivid blue diamond.
The ring is primarily notable due to the unique blue diamond. Blue diamonds are “among the rarest and most sought-after colored diamonds and only one stone in around 10 million has colour that rates this designation.” They “form very rarely, when a specific set of natural conditions and trace elements of the mineral boron are present in the earth” and as such command enormous sums at auction.
The ring has “a bold geometric setting” and has a “distinctive look, reminiscent of Egyptian art in particular”.
The ring was designed in the early 1970s by the Bvlgari House in Rome. It was purchased in 1972 by a European collector, for around $1,000,000, as “a gift … to his wife in celebration of the birth of their first baby boy.” The ring had been in the family’s possession continuously for almost 40 years until 2010.
On 20th October 2010, the Bvlgari Blue was sold at auction for $15,762,500 by Christie’s, New York. The top lot in "Jewels: The New York Sale", it was the subject of “a bidding battle between one client in the room and two clients on the phone.” It was sold to an unnamed Asian buyer.
The auction of the blue diamond set “a new world record price per carat for a blue diamond at auction”, selling for “a staggering $1.4 million per carat”. The 1972 sale price of $1,000,000 was equivalent to $5,000,000 in 2010. As such, the Bvlgari Blue has tripled in value over the last 40 years.
Rahul Kadakia, the Head of Jewelry for Christie's America, commented on this significant increase in value, asserting that it represented “the incredible resilience of diamonds in today's volatile economic environment and the true, lasting value of fine jewellery."
