how long will it take for a diamond to became a diamond?

Answer 1

This turns out to be a difficult question to answer. The main reason is
that diamonds do not themselves contain anything useful for radioactive
dating. They are almost pure carbon, and are much too old for radiocarbon
dating. An internet search I did revealed some new work, published in
1998, (http://earth.leeds.ac.uk/ygs/programme/year1998/mar98.htm#Pearson)
that suggests that at least one diamond from Siberia may have grown over a
period of more than 300 million years. This work was done by dating
inclusions of sulfide minerals (little crystals trapped inside a bigger
crystal) within the diamond using Renium and Osmium.

Diamonds grow more than 150 kilometers deep in the mantle and their growth
rate may be highly variable depending on the local abundance of carbon
(which is very scarce in the mantle in general), the temperature, the
presence or absence of melt, and other factors.

The time it takes to make a diamond should not be confused with the
diamond's age. A diamond could form and then just sit around for a long
time. Many of the diamonds we find at the surface of the earth or in mines
are very old, perhaps 3 billion years (the Siberian diamond inclusions
mentioned above are apparently 3.4 to 3.1 billion years old).

Answer 2

A diamond is already a diamond! If you mean "How long does it take coal to become a diamond?" Short answer: coal to diamond is a myth. Coal and Diamonds are related in the same way Humans are to Apes, they come from the same thing, but evolve differently, and can't be turned into each other. Millions of years ago, pockets of carbon dioxide formed deep beneath the Earth's crust, Extreme heat and pressure caused the carbon atoms to crystallize forming diamonds.

Answer 3

Diamonds are said to be millions of years old, but I don't think they take that long to form. Apollo Diamond of Boston has a process where they break down methane with microwaves into hydrogen gas and carbon vapor. the carbon plates out onto seed diamonds, like frost on your windows in the winter, and they grow. I don't know that this is like the natural process, but they can grow diamonds large in weeks that way. I suppose that methane could have bubbled up from the depths of the earth long ago, been trapped in pockets and subjected to heat or radioactivity or something, which caused the methane to break down, forming diamonds Hope this answers what you wanted to know!

Answer 4

Diamond to Diamond=0 now if your asking coal to diamond it's like the first answer

Answer 5

If it's a diamond then it's already a diamond

Answer 6

it takes a couple thousand years for the coal to be compressed enough to create a diamond and be mined

Answer 7

a diamond is a diamond NO TIME AT ALL

Answer 8

it can take 100 years +.. and a lot of pressure for a nautral diamond.

Answer 9

i think it takes like hundreds of years maybe ill make a diamond factory in my backyard for all my great-great-great-great-great-grandkids lol ;o)

Answer 10

few millions of years I think... you'll be too old my then LOL
