Very rare $25.6 million blue diamond will be put on display in California

Blue Diamond Worth $25.6 Million shown in this video

What makes this diamond quite unique is its colour saturation and shade, combined by an amazing clarity, which granted it the grading of “fancy vivid” with an “internally flawless” clarity by the Gemological Institute of America.

When exposed to ultra-violet light, blue diamonds usually let off a blue-green glow for short lengths of time. The Blue Moon, instead, emitted an orangey-red phosphorescent glow for about 20 seconds after being bathed in ultra-violet light, Forbes reports.

The precious gem’s extra-special qualities don’t stop there. The Blue Moon is expected to be able to provide clues about the forces at play deep within the Earth when the diamond was created at least a billion years ago, the curator of the National Gem and Mineral Collection at the Smithsonian Institution in Washington, told Bloomberg earlier this month.

Colour boom

Coloured diamonds are the world’s most expensive stones. A 14.82-carat orange diamond sold for $36 million at Christie’s International in Geneva in November, setting a record $2.4 million a carat. The same month, Sotheby’s sold the Pink Dream, a 59.6-carat pink stone, for $83 million.

The Cullinan mine, located at the foothills of the Magaliesberg mountain range, is renowned for producing large blue diamonds and is the site of the discovery of the world’s largest gem 109 years ago.

The world’s biggest certified diamond is the 3,106-carat Cullinan, found at the mine near Pretoria in 1905. It was cut to form the Great Star of Africa and the Lesser Star of Africa, set in the Crown Jewels of Britain.

Treasure hunt madness after $20,000 diamond falls from the sky

A $20,000 cushion-cut diamond that dropped 100,000 feet from space after being placed inside a helium balloon, which popped over a field in the East Midlands region of England, has yet to be found.

The 1.14 carat gem, which went missing earlier this month, is the central element of a PR stunt by London jeweller 77 Diamonds, called #DiamondsIntheSky. And while the marketing strategy seems to have gone terribly wrong, the truth is the best part of it is still to come, because whoever stumbles across the stone gets to keep it, co-founder Tobias Kormind told The Telegraph.

And someone will, as inside the box containing the diamond there are two GPS trackers fitted with SIM cards. The jeweller can call the numbers anytime to get an SMS ‘pinged’ back containing the latitude and longitude of the package. Dropping those coordinates into Google Maps reveals a 500 metre-area where the diamond may be found.

Golconda diamond fails to find buyer at Christie’s auction in Hong Kong

A pear and cushion-shaped diamond and emerald necklace, having two Golconda diamonds, failed to sell at Christie’s Magnificent Jewels auction held this week in Hong Kong, as Chinese buyers demonstrated more selectivity than at previous auctions.

The rock, the centrepiece of a diamond and emerald necklace, is known as “The Eye of Golconda,” and it was expected to fetch up to $10 million. Instead, it remained unsold.

A 9.38 carat pear-shaped fancy intense pink diamond fared better, selling for almost $6 million (or $636,117 per carats), still at the low end of its estimate.

The Indian medieval region of Golconda is universally famous for the mines that have produced the world’s most famous and coveted gems, including the Hope DiamondIdol’s Eye, the Koh-i-Noor and the Darya-i-Noor.

Overall Christie’s sold about $390 million worth of art during the five-day spring sale, with jewellery showing disappointing results, as only 81% of the 300 lots on offer sold with a 73% sell-through value.

An 8.41 carat, pear-shaped, flawless pink diamond will go under Sotheby’s hammer in Hong Kong on Oct. 7, with the rare gem expected to fetch up to US$15.4 million.

If the rock reaches its low-bid estimate of $1.5m per carat, it would gain a place among the top three pink stones ever sold at auction on a per-carat basis.

Quek Chin Yeow, chairman of Sotheby’s international jewellery business in Asia, highlited the concentrated shades of pink in this particular rock. “Combined with the exceptional clarity, it is not surprising that it would command the highest per-carat pre-sale estimate for any pink diamond to date,” he said in a press release.

According to auction house, growing wealth in Asian has produced new buyers big diamonds, with coloured ones becoming increasingly popular in the past decade.

These gems rarity has helped push diamond prices up, to the point that coloured rocks are now the world’s most expensive stones. A 14.82-carat orange diamond sold for $36 million at Christie’s International in Geneva in November, setting a record $2.4 million a carat. The same month, Sotheby’s sold the Pink Dream, a 59.6-carat pink stone, for $83 million.

Viewings will be held in Singapore, Taipei, New York, London, Geneva and Hong Kong before the auction.

A suitably named hero diamond, the “Argyle Cardinal,” is the main piece of Rio Tinto’s annual tender of ­Argyle’s rare coloured diamonds being held in Sydney, Australia, between Tuesday and Friday.

The 1.21-carat radiant cut rock, expected to fetch over US$2 million, is one of the only 13 Fancy red diamonds included in the annual display in the last 30 years.  It was named after a small red northern American bird.

What makes the “Argyle Cardinal” even more special is the fact that there are only 30 known red diamonds in the world.

What makes the “Argyle Cardinal” even more special is the fact that there are only 30 known red diamonds in the world.

“These are all one-of-a-kind gems that will take their place in the history of great collectible diamonds,” Argyle Pink Diamonds manager Josephine Johnson said in a statement.

Last year a precious rock like this one set a record at auction at Christies’ in New York of $1.6 million per carat.

Increasingly rare

Diamonds are becoming an increasingly rare item as fewer mines remain in operation and new discoveries dwindle.

Polished diamond prices increased 4.5% in the first half of 2014, according to a study published Tuesday by EY, and further upside is expected for the second half of the year, driven mainly by rising demand, recent transactions and availability of financing.

Since the 1870’s, when the first kimberlite was found, another 6,800 kimberlites have been discovered worldwide. Of those, only about 1,000 contained diamonds, and of those only 60 actually contained diamonds on an economic level.

Rio Tinto controls the market for pink diamonds from the Argyle mine in Australia. Around 65% of the world’s diamond supplies come from the Cullinan mine in South Africa.

Tender viewings will be held in Sydney, New York, Hong Kong and Perth with bids closing on October 8, 2014.
