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.

History Of Diamonds on video

white-rbc-diamond-black-background-image-www-worldwidediamonds-info

Diamonds are by far the most popular gemstones used in modern jewelry, but do you know where they came from?

Diamonds have been considered to be beautiful and very valuable for a long time. In the 1st century AD, a roman naturalist said that the “diamond is the most valuable, not only of the precious stones, but of all things in the world.”

The international love of diamonds started in India. They were trading diamonds as early as the 4th century BC. Eventually, they started trading to the Europeans, and became very popular among them by the 1400s.

In the 1700s, Brazil became a diamond-mining powerhouse.

The int 1800s, after the French Revolution, western Europe and the US became more wealthy and the demand for diamonds exploded.

By the 1900s, South Africa mined 90% of the world’s diamonds.

Recently, diamonds have been found in Australia and Canada.

Diamonds have truly withstood the test of time and will always be in fashion.

Who stole this $5 million diamond-encrusted gold eagle statue? Video,Pics & Story

Canadian Police are looking into the robbery of an 18-pound, solid-gold, diamond-encrusted eagle statue in British Columbia, worth about $5 million according to the statue’s owner.

The golden statue was supposed to be the centrepiece of a campaign launched in conjunction with a series of books and events to raise money for cancer research.The statue, called The Maltese Eagle, was supposed to be the centrepiece for “The World’s Greatest Treasure Hunt: Quest for the Golden Eagle,” a campaign launched in conjunction with a series of books and events to raise money for cancer research, owner Ron Shore, who operates a telecommunications company, told CNN.

The eagle had been on display for four days at the Art! Vancouver exhibit and was in transit to a secret vault when the theft occurred on Sunday night.

Shore said he mortgaged his house and used inheritance money and credit cards to finance the making of the eagle.

“Unfortunately what will probably happen is that all of the jewels will be pulled out of the head because it had basically a cape of diamonds,” sculptor Kevin Peters, who spent nearly four years creating the statue, told NewsTalk 770. “And it has three types of gold and will be probably melted down.”

But taking the jewells off would be difficult, and a novice would likely end up breaking some of the gems, David Ritter, president of the Canadian Jewellers Association, told News 1130.

One of the largest gems present in the statue was the Atocha Star, a 12-carat emerald that was recovered in 1985 from the Nuestra Señora de Atocha, a Spanish treasure galleon that sank in 1622. The Atocha Star is itself estimated to be worth at least $3 million.

This is not the first time the eagle has been targeted. In a 2010 interview, Shore told The Vancouver Sun that RCMP accompanied him and the eagle to an event because of concerns organized crime elements might be looking to steal it.

Sotheby’s Acquires “Pink Star” Diamond after Buyer Defaults

Published on Feb 28, 2014

Sotheby’s acquires the “Pink Star” diamond, which fetched a world-record price in November, after its buyer couldn’t pay and defaulted.

Sotheby’s said it acquired the “Pink Star” diamond, which had fetched a world-record price in November, after its buyer couldn’t pay and defaulted.

New York-based diamond cutter Isaac Wolf outbid three rivals last November to pay 76.3 million Swiss francs ($83.02 million) for the flawless pink diamond in an auction guaranteed by Sotheby’s.

In a post-earnings conference call, the auction house said it reversed the related commission revenue as a result of the buyer default and recorded the pink diamond in inventory at a value of about $72 million.

“We are currently in discussions with the buyer, while also considering other alternatives,” Patrick McClymont, Sotheby’s CFO said on the call with analysts. “In the meantime, we are quite comfortable with our valuation, and see real value in owning the diamond at this price.”

The world-record price for the diamond, which had been renamed “The Pink Dream” after Wolf acquired it, had included a “buyer’s premium,” or commission fees. The diamond’s pre-sale estimate was $61 million.

The 59.60-carat Pink Star was the main attraction at Sotheby’s November jewels sale in Geneva, which was the highest jewelry sale total for a single auction in history – $199.5 million.

On Thursday (February 27), Sotheby’s reported weaker-than-expected quarterly profit, hurt by higher operating expenses and increased competition. The auctioneer reported earnings of $1.30 per share that missed analysts’ estimates of $1.40 per share, according to Thomson Reuters I/B/E/S.

Billionaire hedge fund manager Daniel Loeb mounted a proxy fight with the goal of winning three board seats after the auction house’s promise to return $450 million to shareholders failed to appease activist investors.

Hong Kong Tycoon Grabs $48.5Mn Blue Moon Diamond for Daughter at Sotheby’s Auction

Published on Nov 12, 2015

An exceptionally large blue diamond sold Wednesday for 48.6 million Swiss francs ($48.5 million) – a record price for any jewel at auction, Sotheby’s said, culminating two Geneva auctions in which a convicted Hong Kong tycoon, Joseph Lau, bought rare coloured diamonds for his daughter.

Hong-Kong-billionaire-tycoon

The 12.03-carat ‘Blue Moon’ diamond, set in a ring, was said to be among the largest known fancy vivid blue diamonds and was the showpiece gem at the Sotheby’s jewelry auction.

A packed room broke into applause after the hammer came down at a price of 43.2 million Swiss francs, excluding fees – within the pre-auction estimate range of about 34 to 54 million francs.

The Blue Moon – so-called in reference to its rarity, playing off the expression “once in a blue moon” – topped the previous record of $46.2 million set five years ago by the Graff Pink, Sotheby’s said.

The diamond also set a new record of more than $4 million per carat, capping the daylong high-end jewelry sale that reaped roughly $140 million.

Blue diamonds are formed when boron is mixed with carbon when the gem is created.

This blue diamond may become the most expensive gem ever sold at auction

this-blue-diamond-may-become-the-most-expensive-gem-ever-sold-in-auction image www.wordwidediamonds.info

A rare 12-carat, flawless blue-coloured diamond, known as Blue Moon, may soon become the most expensive gem ever sold at an auction as it is expected to fetch up to $55 million when it goes under Sotheby’s hammer on Nov. 11, in Geneva.

To set the world record price for any diamond put to auction, Blue Moon must sell for more than $46.2 million, which is what The Graff Pink went for in 2010.

If it does fetch over that price, the South Africa-mined rock would also be the most expensive blue rock ever sold, beating the Zoe Diamond, which fetched $32.6 million in 2014, international auction house Sotheby’s said.

Blue Moon was polished out of a 29.62-carat rough diamond found by Petra Diamonds (LON:PDL) at the Cullinan mine in South Africa. Cora International, a New York- based gem-cutter, purchased the rock and took more than six months to prepare the stone.

Its name is a reference to the idiom “once in a blue moon,” a hat tip to the rarity of finding a diamond of that shade and clarity, Sotheby’s said.

5 Quick easy tests in spotting a Fake Diamond

Tell if a Diamond is Real Step 1.jpg

One of the most common questions that gemologists are asked is how to tell the difference between a real diamond and a fake stone.

We spoke with Reyne Hirsch, a 20th century decorative arts expert and consultant for the global online marketplace Lofty, about how to tell when a diamond is real, and when and why to take it to an expert.

Test At Home
“We see a lot of estate jewelry that comes up in our line of business,” Hirsch explained to Business Insider. “People who are selling their parents’ estate assume the money is in the house itself — but sometimes the things inside the home have a lot more value than they think.”

For jewelry you inherit or find at garage sales, it’s best to do a few simple DIY tests before bringing the pieces in for a gemologist to look at.

1. Look at the diamond and setting through a loupe.

Diamonds through a loupe

A loupe is a magnifying glass that you can buy at any jewelry store and will let you take a closer look at your gem and setting.

“When you’re looking at a diamond, there are a few things you’ll notice,” Hirsch told us. “First, the majority of diamonds are made in nature so that means you’re going to see some imperfections in the carbon. A fake stone would be perfect — absolutely perfect.”

Hirsch cautions that certain lab-grown stones will also look perfect through the loupe, and so you should be cautious before discarding perfect gems. It can be a clue, however, to take a closer look or bring the stone to an expert.

Second, observe the diamond’s edges. “When you’re taking a look at a diamond through a loupe, a real stone is going to have sharp edges, and a fake stone will have rounded edges,” Hirsch explained.

Lastly, look at the mounting and etchings, especially any marks that signify what metal was used. “If the metal is gold plated or silver, chances are it’s not a diamond because why would you put a nice stone mounted in such a cheap metal?” Hirsch said. “Most diamonds are mounted in gold or set in platinum.”

“Also take a look at the mounting itself and how that diamond is set,” she added. “If the setting looks like it’s of poor quality, that probably means it’s not going to be a real diamond either.”

2. Rub sandpaper against the stone.

Uncut diamond

This is an easy test since diamonds are one of the world’s hardest materials and won’t be scratched by the rough surface. “If it’s a diamond, it will remain perfect, if it’s a cubic zirconium, it will scratch it up,” Hirsch said.

3. Do the fog test.

The right one is a 0.41 carat synthetic lab grown diamond and the left one is a slightly larger natural diamond, both visually indistinguishable from each other.

Breathe hot air on your diamond the same way you would if you were fogging up a bathroom mirror.

“A fake diamond will fog up for a short period of time whereas a real diamond will not because it won’t retain the heat,” Hirsch explained.

4. Hold it in the light to see how it sparkles.

Diamond reflecting in the light sparkly

The way that diamonds reflect light is unique: Inside the stone, the diamond will sparkle grey and white (known as “brilliance”) while outside of the gem, it will reflect rainbow colours onto other surfaces (this dispersed light is known as “fire”).

A fake diamond will have rainbow colours that you can see inside the diamond.

“People have a misconception that diamonds sparkle like a rainbow, but they don’t,” Hirsch said. “They do sparkle, but it’s more of a grey colour. If you see something with rainbow colours [inside the stone], it could be a sign that it’s not a diamond.”

Still confused? This is a good explainer of brilliance versus fire.

5. Look at the stone’s refractivity.

RTR3O4F6

Diamonds are so sparkly because of the way they refract and bend light. Glass, quartz, and cubic zirconium may mimic a diamond’s brilliance, but they have much lower refractive indexes.

This means that if your stone isn’t in a setting, you can place it over a newspaper and the light will scatter inside the real diamond and prevent a black reflection. A fake diamond will let the black shine through, and you may even be able to read a word depending on the size of the fake stone.

If your diamond is mounted, make sure you can’t see through it to the mount itself — that’s a very bad sign.

Test With A Gemologist
Once you’ve done all your home tests, it’s time to take your jewels that could be diamonds to a gemologist.

“You don’t want to take a box full of jewelry because it will cost you money for them to look,” Hirsch explained. “I would be flat out frank and say you’re not interested in selling, but just ask if they’re worth you paying attention to or if it’s fine to let the kid’s play with them.”

Diamond through a loupe

But don’t just take your diamonds to any old jeweler. It’s important to do your research and find a qualified gemologist.

“At mall stores, they tend to have sales people — not gemologists,” Hirsch said. “They just know what sells in their stores and what appeals to the masses. Look beyond the average jewelry store and go to a local antique stores or ask your local antique jewelry store who is a reputable gemologist in town who knows about diamonds.”

Even if you know the jewelry you have contains diamonds, it can pay off to take them to a gemologist to know how much they’re actually worth.

“Say you have five, 1-carat diamonds on the table — the cut, colour, and clarity will be a huge factor in why one is worth $US800 and one is worth $US10,000,” she said.

What it could be instead of a diamond:
White topaz — Topaz is a mineral that is usually tinted yellow, red, brown, or pale grey, but can sometimes be white or appear colorless. Diamonds are much harder than topaz, however, which can wear down and scratch over time making it dull or cloudy.

White sapphire — We usually think of sapphires as being blue, but this gem can also be white. Just like topaz, sapphires are prone to more damage than diamonds and do not have the same fire and brilliance of a true diamond.

Cubic zirconium — Mass-produced since 1976, cubic zirconium scratches easily and does not have the same fire and shine as diamonds.

Moissanite — Moissanite is harder than cubic zirconium and these stones are visually dazzling. The main difference is that moissanites have a different brilliance than a diamond where you can see rainbow colours within the stone, giving it a disco ball effect.

Lab grown — Lab-grown diamonds are technically “real” diamonds both chemically and physical, but they will not fetch for the same price as a mined diamond. Hirsch says they usually sell for about 20% to 30% less than a traditional diamond.

So the next time you run across something you think is just cheap costume jewelry, it’s important to test it — just in case.

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

Blue Diamond Worth $25.6 Million shown in this video

this-extremely-rare-25-6-million-blue-diamond-may-hint-at-earths-origins image www.worldwidediamonds.info

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.
