Gold is one of the world’s most precious metals

All of the gold in the world could be compressed into an 18 yard cube, which is about 1/10 the mass of the Washington Monument

It is recorded that only 88,000 tons of gold have been taken from the earth since recorded history, leaving far more yet to be discovered.

A one ounce gold nugget is more rare to find than a five carat diamond. The amount of gold nuggets being found in the world is less than one percent. Even though gold is rare, it is far easier to find than winning a major state lottery. Because of its rarity, a gold nugget can be worth three to four times its value of gold. An authentic gold nugget has long been considered a gem stone because of its rarity and beauty.

Gold is so heavy that one cubic foot of it weighs half a ton. Gold is six to seven times heavier than other materials that equal its size. The largest gold nugget found in the U.S. weighed 195 pounds; it came from California.

Gold can be hammered into sheets so thin that a pile of them an inch high would contain more than 200,000 separate sheets. Gold can be hammered so thin that sunlight can shine through it

A single ounce of gold can be drawn into a wire 60 miles long.

In every cubic mile of seawater there is 25 tons of gold! That’s a total of about 10 billion tons of gold in the oceans; however, there’s no known way to economically recover it.

Gold is considered one of the most important metals in jewelry making. Gold is so soft it is seldom used in its pure form. Jewelry that is marked 10K is made of 10 parts gold and 14 parts of another metal. The hardness of pure gold (on moh’s scale) is 2 1/2 – 3; the melting point is 2,063° F; specific gravity is 19.32, and tensile strength is 19,000 psi.

Gold can be transmitted from platinum by nuclear reaction. But because of the rarity of platinum, it is far too costly.

The United States government banned private ownership of gold which lasted 41 years, then lifted it on December 31, 1974.

Gold is chemically liquefied and injected into the muscles of thousands of rheumatoid arthritis victims in the U.S., and it is said that the treatment is successful in seven out of 10 cases.

Gold is used in window glass and astronaut helmets to reflect off infrared rays while allowing sunlight to pass through, and at the same time keeping it cool.

Gold is inactive chemically and is not affected by air, heat, moisture and ordinary solvents.
