Exquisite Bulgari blue diamond ring circa 1965 is expected to fetch over $2.3m at Bonhams auction

Andrea Divirgilio / February 13, 2013

Royalty and celebrities which favors the rare blue diamonds across the ages, now stands a chance to grab an exquisite blue diamond ring that epitomizes that ‘golden era’ of elegant simplicity at the Bonhams Fine Jewelry sale on 24th April 2013. This extremely rare and fancy deep-blue diamond is set in a ‘Trombino’ ring circa 1965 made by Bulgari, the world-acclaimed Italian jeweler favored by Hollywood film stars, and the epitome of design fashion and innovation during the 1960s. However, it’s interesting to note that blue diamonds are very rarely seen on the market and the sought-after fancy colored diamonds are now seeing a skyrocketing demand amongst collectors who have chosen to invest in natural colored diamonds. And it becomes apparent from the sale of rare blue diamond by Bonhams in year 2011 for $2.9 million, rare BVLGARI blue diamond was offered on sale for over $12 million at Christie’s, and another brilliant sky-blue diamond got sold for $6.4 million at Sotheby’s. Over the centuries, they have delighted the royals and ultra-elites, with the most famous being the ‘Hope Diamond’ bought by King Louis XIV of France, and is now one of the world’s most expensive diamonds.

Structurally very pure, the blue diamonds account for less than 1% of all diamonds mined. And, the stunning color blue is derived from small atoms of boron mixing with the carbon atoms in a diamond, affecting the absorption of light passing through the stone and lending it a blue appearance.

Weighing 5.3 carats, the fancy deep-blue diamond set into a 1965 Bulgari ring, will sell for an estimated price of $1.5-2.3m.

Also, we have recently seen the sale of of a 76-carat Golconda diamond, the huge, internally flawless Archduke Joseph diamond from India’s fabled Golconda mines for a record $21.48 million at auction in Geneva on November 13.
