how are diamonds made.?

Question

i'vw always wondered how diamond are formed under ground, what makes them grow and how

Answer 1

Diamonds are in fact carbon. So you could say that a lump of coal is a young diamond. Diamonds take millions of years to form naturally and they are made when carbon is under extreme pressure as one would find in the earth's crust. As a point of interest, there are now ways of putting carbon under extreme pressure and making diamonds. There is now something more sinister going on. The human body is made up of carbon and after cremation the ashes, carbon, can be made into a diamond. So when a loved one dies you could wear them as a ring or earring or necklace. Thought that might be an interesting little snippet for you.

Answer 2

A diamond is one of the three known allotropes (different kinds) of Carbon. There are two ways a diamond can be made: naturally or synthetically. They can also come in many different colors. A diamond is an isometric-hexoctahedral crystal of Carbon atoms. Naturally, hey are created when trapped pockets of Carbon gas deep inside the Earth is compressed to extremely high pressures and subjected to very high temperature. Eventually, the intense pressure is enough to compress the gas into a solid crystal and the diamond is formed. Over the next few million years, volcanic pipes (not volcanoes) push the stones up to the surface of the Earth. If the diamond was created synthetically, it is essentially the same process. However, the creation of a synthetic diamond does not achieve as high of temperature or pressure and as a result the stone looks different when viewed under a ultraviolet light. The process is just injecting Carbon gas into a creation chamber at incredibly high pressures, then heating the gas. A colored diamond is created when a small amount of another gas makes the Carbon impure. For example, Nitrogen impurities will make a yellowish color.

Answer 3

How are diamonds made? Well, under natural circumstances, it takes putting carbon under pressure millions of years to create a diamond. This is why diamonds are so expensive to purchase. Fortunately, man is no longer confided to waiting for nature to create diamonds. Diamonds made by man can be created much faster and the quality is higher than ever before. In fact, a layman may now find it hard to tell the difference between a fake diamond from a real one.

Fake Diamonds – Spot a Counterfeit Diamond

Here are some easy tips you can use to determine fake diamond - or real?

Ask. Ask the salesman straight out if the diamond you are looking at is a fake or real. A reputable salesman will give you an honest answer.

Wear and Tear. Real diamonds are almost indestructible. If you seek chips or scratches on the gem, chances are your diamond is made by man and not nature.

Documentation. Ask for a certificate from the Gemological Institution of America. The GIA is the largest diamond grading authority in the world.

Appraisal. Take the diamond to a certified diamond appraiser. While the naked eye may not be able to distinguish between a real diamond and fake one, appraisers have the tools needed to tell the difference.

Setting. Look at the quality of the setting. If the diamond is fake, there is a higher chance the setting will be of poor quality than if the diamond is real.

Fake or real, a beautifully cut diamond in a dazzling setting can be a real eye catcher. The trick is not to pay more for your diamond, fake or real, than it is really worth. By taking the proper precautions to know what you are buying, you can enjoy your diamond purchase without regrets.

Answer 4

Jewellery-standard diamonds have been made, artificially, in just one day. Up to 5 mm (0.2 in) thick, these are the largest gems ever produced using a process called chemical vapour deposition—i.e. the diamonds were made ‘almost from thin air’.

New Scientist, 6 March 2004, p. 17.

Reports of rapid production of diamonds are now almost commonplace (Creation 25(3):7, 2003; 25(1):9, 2002), showing that natural diamonds did not need millions of years to form, in direct contrast to evolutionary ideas about diamond formation.

Answer 5

Diamonds are made of dead plants and animals. The lifeless forms degrade into the ground and the carbon within them is used to create fossil fuels. However, deeper underground where the pressure and heat is greater and the carbon remains undisturbed for longer, it undergoes another molecular change and becomes a diamond.

Coal and diamonds are very similar in their makeup but try giving your girlfriend a ring with a piece of coal stuck to it.

Answer 6

A laboratory diamond is not a "fake." Any gem that is composed of the correct chemical elements is genuine. The distinction between diamonds grown in a volcano and diamonds grown in a laboratory is that of NATURAL and ARTIFICIAL. Not "real" and "fake." Both the lab diamond and the natural diamond are real.

The fake "diamonds" are gems that are made of quartz, cubic zirconium, or corundum and sold as diamonds. These aren't diamonds at all. They're fakes because the seller is trying to trick you into paying more money than his rock is really worth, by making you believe you're buying gems made of tetrahedral crystal carbon, when really they're made of silicon oxide or some other cheap stuff.

There's a lot of fakery in the gem business, much dishonesty. It's easy to get tricked. So don't buy gems.

Answer 7

Diamonds were formed below the earth's mantle where pressures and temperatures were sufficient to compress carbon into diamonds.
They make artificial ones by heating and then cooling carbon in an iron core that contracts,producing enough pressure to form small artificial diamonds.

Answer 8

I don't know what happens underground, but I do know what happens above. The ore is put on a conveyer belt and smashed only strong enough to get rid of rock around the diamond. Then they're dipped in acid to remove rock left on the diamond. Later, they're polished and proffessionals decide how to cut it to not waste too much. They're cut and rounded. Finally, they're brought to more pros who examine it and if it's good, it's used on jewelry.

Answer 9

simply, its carbon, under tons of heat and pressure over "X" amount of time, X can be man made or natural time. the thing i dont understand is why doesn't someone make a diamond the size of a football or basketball, if man can make them. now that is the real question.

Answer 10

A number of people have given you the answer (carbon subjected to extreme heat and pressure deep in the earth) but all have failed to mention that Superman can make real beauts just by squeezing a lump of coal in the palm of his hand! AND they come out cut and polished already!
