The Highest Priced Investments

Investments come in all shapes and sizes and are made for all sorts of different reasons, but people need to be assured they are getting value for money.

These top 10 items were placed at the top of the list in a very unscientific survey.

1.Positrons
Positrons, at a massive cost of $US250 billion per kilo, are the most expensive item you could purchase.

Positron, or antielectron, or the antimatter counterpart of the electron, are created when a low-energy positron collides with a low-energy electron and annihilation occurs, resulting in the production of two or more gamma ray photons.

Before you dash away thinking this is going to be a scientific paper, the big surprise is that chocolate contains positrons. The major use for antimatter is in medical diagnostics, (PET scan).

Scientists have found that beams of antimatter are constantly produced on earth and fired into space above thunderstorms.
Although antimatter is extremely difficult to produce and capture, just one gram of positron, would drive your car for approximately 100,000 years.

2.The Yellow Stamp
Judging by weight and size 'The Treskilling Yellow', a Swedish stamp, is allegedly 'The Most Valuable Thing In The World'.

They Yellow Stamp was sold at auction in 1996 for $2.3 million and is listed in the Guinness Book of Records.

The Swedish National Testing and Research Institute in Boras, Sweden has estimated the stamp, weighing just 0.0009 ounces to be worth $US 85.98 billion per kilo.

3. Platinum
Platinum, one of earth's rarest elements, with an incredible resistance to corrosion, is considered a ‘noble’ but heavy metal, which leads to health issues upon exposure to its salts, even though it is not classed as toxic.

While only a few hundred tons are mined each year, it is used in some thermometers, laboratory equipment, electrical contacts, dentistry equipment and jewelry. In some cases it is used in chemotherapy against certain types of cancer.

A kilo of this rare metal would set you back $53,700 per kilo.

4. The Koh-i-Nor Diamond
The fine white Koh-I-Nor, diamond, a 105 carat (21.6g), was once considered the largest known diamond on the planet.

Diamond, the hardest known substance to man, is used in many industries, from cutting, to abraiding and is used in x-ray machines and microelectronics, because of its ability to transfer heat away from sensitive circuitry.

While no one is prepared to place a price on the Koh-i-Nor diamond, some authorities claim a clear white diamond's value is $250,000/g at the top of the range, or around $50 million per kilogram.

5. Gold
Gold on average costs $45,000 per kilo. The biggest nugget ever found weighed 4.85 kg.

This precious and rare metal has long been found to be a 'transportable' commodity and is the least reactive chemical element known.

6. Palladium
Palladium, a rare lustrous silvery-white metal, is part of the platinum group of metals, PGMs. A quarter of all manufactured goods either contain PGMs, or PGMs are part of the manufacturing process.
A kilo of palladium will cost you around $21,500.

7. No. 5 1948 Painting

If you had purchased The American painter, Jackson Pollock's painting, No. 5 1948 in 2006, it would set you back a cool $151.8 million. Painted on a 243.8 cm x 121.9 cm fibreboard it would probably cost around $10.1 million per kilo.

8. Antilla
Antilla it the most expensive house in the world. The 570 feet of mostly glass, of 'Antilla', towers over the slums of mid downtown Mumbai, India, at just 570 feet high, the 27 storey building cost around $2 billion, almost twice the cost of Buckingham Palace. With 400,000 sq ft it is said to have more floor space than the palace of Louis XIV at Versailles.

That works out at around $5000 per square foot.

9. Green Monkey
If Florida born colt, Green Monkey, weighed the same as an average thoroughbred, he would have weighed approximately 1000 pounds at the time of sale, when he was sold for $16 million in 2006, making the colt around $36,000 per kilogram.

He was the most expensive horse ever sold even though he had never won a race.

10.Bugatti
The 1931 Bugatti Royale Kellner Coupe was originally built as a Grand Prix racer. It became the most expensive car on earth, when it was sold at $8,7,000 in 1987. This one of a kind costs only $2,800 per kilogram.
