10 of the most expensive diamonds in the world.Video,

LARGE MOST EXPENSIVE DIAMONDS OF THE WORLD

10. The Heart of Eternity ($16 million)
The stone that was made into the heart of Eternity Diamond was found at the world’s largest supplier of blue diamonds, the South African Premier Diamond Mine. Blue diamonds are incredibly rare with, on average, only one being found every year, and this one was an amazing find. The rough stone was 777 carats when it was dug up, and the owners waited until they had the perfect design idea before they started cutting it. The result was The Millenium Blue Diamonds- a series of heart, pear drop and oval shaped diamonds of which the Heart Of Eternity is the largest.
In recent years it has been on tour at various exhibitions, including at the Millennium exhibition in London in 2000, followed by the Smithsonian museum. It was reportedly bought in 2012 by Floyd Mayweather to give to his fiancée, but no details of the selling price were ever revealed. The $16 million price tag is an estimate based on its size and color, but the finished piece could be worth far more when you consider what a rare piece it is.
9. The Moussaieff Red Diamond ($20 million)
Diamonds come in many colors, but red ones are particularly rare. According to the Cape Town Diamond Museum there have only been up to 30 true red diamonds ever found, with most of them being less than half a carat. A farmer in Brazil found the rough stone that was to become the Moussaieff Red Diamond in the 90’s. At a weight of 13.90 carats it immediately became the center of attention.
The William Goldberg Diamond Corporation from New York then bought it, and decided to cut it into a triangular brilliant cut. This process would mean losing 8.79 carats, but the resulting cranberry colored 5.11 carat gem is simply stunning. It was originally named the Red Shield, but was renamed by the Moussaieff Jewelers when they purchased it for about $8 million at the turn of the century. This diamond has regularly been to exhibitions, being shown alongside other ones in the Smithsonian. Were it to be sold, it would be expected to cost at least $20 million.
8. The Perfect Pink ($23 million)
When it sold for $23 million in 2010, the Perfect Pink Diamond was the most expensive jewel that had ever been sold in Asia. It weighs 14.23 carats, is graded as fancy intense pink, and is set in a rose and white gold ring with rectangular shaped diamonds on either side. Pure Pink diamonds of more than 10 carats are very unusual, with only 18 examples having gone to auction in the past 244 years; none of which was classified as intense pink at the time of sale. This makes the Perfect Pink a truly unique piece, and explains why it sold for ten million dollars more than had been expected.
7. The Wittelsbach Diamond ($23.4 million)
The first records of the Wittelsbach Diamond come from back in the 17th century when it was sold to Louis XIV of France. It has a rare blue color, and weighs 35.56 carats. The stone has a royal history, having been passed down through families since the 1600’s. It went from France, to Spain, and over to Germany, where it accompanied the German King Louis III to his burial place in 1921.
At some point in the 30’s it was sold to raise money for the German government, and from here things get mysterious. No one seemed to know who had bought it, and it somehow got replaced with a piece of blue glas in the museum. Rumors of the actual diamond changing hands were rife in the following decades, until 1962 when it reappeared at a jewelery store in Belgium.
It was sold in 2008 for $23.4 million and, to the dismay of diamond historians, the new owner decided that it should be recut, since it had originally been done in the early 1600’s. The resulting stone, now 21.06 carats, meant that both the color and quality were improved, and the estimated price sky-rocketed.

Diamond Services reports a lowering threshold for synthetic diamonds, as man-made stones as small as 0.0025 cts. discovered in New York

Barely visible on the electronic scale, these tiny single-cut diamonds were discovered by Diamond Services to be laboratory grown.

HONG KONG: JULY 11, 2017 – Multiple single-cut diamonds, sized from a quarter point to half a point (0.0025-0.005 carats), which were contained in jewellery recently submitted for testing to a Diamond Services laboratory, have been found to be synthetic, greatly expanding the range of goods that can be considered at risk of improper and deceptive disclosure.

The jewellery in question was originally submitted to Diamond Services’ laboratory in New York, and after several stones were detected as being potentially laboratory grown. Due to their size, the owner agreed that 11 of them set in eight rings, ranging in size from 0.0025 carats to 0.005 carats, could be removed and sent for full analysis at Diamond Services’ facility in Hong Kong. There they were examined once again with Diamond Services’ award-winning DiamaTest system, which ratified that the diamonds were synthetic, and these findings were confirmed by examination with the DiamondView system of De Beers’ International Institute of Diamond Grading & Research (IIDGR) and Diamond Services Mini Raman Spectrometer.

Usually restricted to smaller-sized stones, single-cut diamonds typically have 17 or 18 facets, and some as few as 16, compared to the standard brilliant round cuts, which are made up of the 57 or 58 facets. Most round stones are first polished as single cuts, and then the additional facets are added. But when small stones are concerned, they are left as single cuts.

“To the best of my knowledge, this is the first time that a synthetic single-cut stone has been detected mounted in jewelry, and it is a credit to our Diamond Services procedures and set of equipment,” said Jospeh Kuzi, Diamond Services founder and managing director. “What this means is that almost no diamond can be taken at face value.”

The source of the single-cut synthetics is not immediately apparent, but Kuzi noted that the growing availability of CVD man-made diamond may prove to be a factor. “CVD is being widely in areas outside the diamond industry, and now includes diamond wafers being gown in laboratories for use in the electronics industry. It could be that waste from these labs and factories end up being processed as very small single-cut diamonds for jewellery,” he said.

Diamonds submitted for synthetic screening at Diamond Services facilities are tested using several systems, including the DiamaTest and Mini Raman Spectrometer, both of which was developed by the company. The latter is the only system currently available that can definitely test rough and polished diamonds, both mounted and un-mounted, without the need to refer them for further testing, accurately detecting whether they are HPHT or CVD lab-grown synthetics within seconds.

Diamond Services, which was established in 2012 in Hong Kong, specializes in development of synthetic diamond detection devices. In 2013 it first introduced the DiamaPen®, a hand-held laser device that is able to detect fancy colour synthetic diamonds. In 2014 it introduced DiamaTest®, an innovative system that screens both loose and colourless diamonds for synthetics, for which it won the prestigious JNA 2014 Award. The Mini Raman Spectrometer was introduced to the market in 2015.

Diamond Services synthetic screening services are currently available at the company’s headquarters in Hong Kong (19F Shing Lee Comm. Bldg., 8 Wing Kut St., Central, Hong Kong, tel: +1-852-2536-4555); and in the United States (15W, 47th St., Suite #1404, New York City, tel: +1-844-842-8122).

Yet Another huge diamond unearthed in Lesotho mine

Gem Diamonds discovered this high quality 126-carat, D colour Type IIa rock at Letšeng

Africa-focused Gem Diamonds (LON:GEMD) unveiled Thursday a 126-carat rock unearthed at its flagship Letšeng mine in Lesotho, the latest in a string of major discoveries at the operation this year.

The finding of the high quality D colour Type IIa diamond comes barely a month after the company discovered two massive diamonds at the same mine —  a 151.52-carat Type I yellow rock and a high quality 104.73-carat, D-colour Type IIa stone.

It also follows the recovery of a 114-carat diamond in April and an 80-carat, D-colour Type-II diamond found in May — one of the highest-quality diamonds to come out of the Letšeng mine.

Type IIa diamonds contain very little or no nitrogen atoms, which places them among the most expensive stones.

Since acquiring Letšeng in 2006, Gem Diamonds has found four of the 20 largest white gem quality diamonds ever recovered, which makes of the mine the world’s highest dollar per carat kimberlite diamond operation.

At an average elevation of 3,100 metres (10,000 feet) above sea level, Letšeng is also one of the world’s highest diamond mines.
