If there’s a gemstone that will eternally remain in vogue, it’s the diamond. Hollywood has long been obsessed with the sparkler: The seventh James Bond film in 1971 was named Diamonds Are Forever, while the 1953 flick Gentlemen Prefer Blondes featured screen siren Marilyn Monroe performing Diamonds Are A Girl’s Best Friend — an iconic tune with lyrics that name-dropped jewellers such as Cartier and Tiffany & Co. And just a few years ago, Barbadian singer Rihanna topped the charts with her 2012 hit titled — what else — Diamonds.

So universal is its appeal, that the diamond is well-loved by celebrities (usually when it comes in ostentatiously large sizes) and regular folk (like us) alike. It is traditionally white or colourless, but rare coloured variations in hues of pink, violet, red or blue are also available and highly sought-after. Blue diamonds, in particular, have been stealing the limelight as of late, with at least two major auction houses showcasing them as highlight pieces. These coveted rocks obtain their blue shade from boron atoms trapped inside their crystalline structures, and have been discovered in mines in South Africa, Australia and India.

Here are 5 blue diamonds that are indeed a feast for the eyes. Two will go under the hammer later this month, so you can consider making a bid to get your hands on these beauties.

1
The Sky Blue Diamond

Set on a ring by Cartier, this scintillating clear, celestial blue stone weighs a hefty 8.01 carats and comes in a beautiful square emerald cut. It is estimated to fetch between US$15 million to 25 million (S$20.8 million to 34.6 million) at Sotheby’s Magnificent Jewels and Noble Jewels auction in Geneva, which takes place on 16 November, 2016. The sparkler has been graded Fancy Vivid Blue by the Gemological Institute of America.

Cartier fancy blue diamond ring

One of the highlights of Christie’s Asia’s upcoming Magnificent Jewels auction in Hong Kong on 29 November, 2016, this dazzling Cartier gold ring is mounted with an eye-popping 5.19-carat fancy blue central diamond. The pear-shaped diamond, which is graded IF (internally flawless), is framed by delicate pink diamonds. This lovely piece is expected to achieve between HK$7 million to 9 million (S$1.2 million to 1.6 million).

Blue Heart Diamond

Discovered in South Africa in 1908, this mesmerising 30.62-carat heart-shaped, brilliant cut diamond has made its rounds among some of the biggest names in the jewellery industry. It was first cut by French jeweller Atanik Eknayan, before being acquired by Pierre Cartier and set in a necklace. Decades later, it became the property of Van Cleef & Arpels in 1953 and, in 1959, Harry Winston. The diamond’s last owner was American socialite Marjorie Merriweather Post, who donated it to the Smithsonian Institution’s National Gem Collection in 1964.

Blue Moon of Josephine

This massive 12.03-carat, cushion-shaped rock went under the hammer at a record-setting S$68.7 million at Sotheby’s Magnificent Jewels and Noble Jewels sale in Geneva last November. It was purchased by a Hong Kong billionaire, who named it after his young daughter.

Hope Diamond

This 45.52-carat diamond is believed to be sourced from the Kollur mine in Golconda, India, and was purchased by King Louis XIV of France in 1668. Originally 112 carats, it was recut over the years and set in different designs. Like the Blue Heart Diamond, it changed hands between several owners including Pierre Cartier, Harry Winston and American socialite Evalyn Walsh McLean — who later had it made into a pendant on a white diamond necklace. It was donated to the Smithsonian Institution in 1958.
