How much diamonds are there in the world? And how much are they worth?

Diamonds are not rare. South Africa has a bunch in storage that they hide until the current ones are sold.\n\nAs for worth, that depends on the size of the diamond, cut, clarity, and flaws---and the current market price.

Diamonds are also found in Russia, Australia, and Brazil. They are all between a billion and three billion years old, having formed at least 90 miles below the earth's surface and been carried to the surface in magma pipes. \n\nThe park mentioned by others is Crater of Diamonds State Park near Murfreesboro, Arkansas. I dug for diamonds there when I was twelve years old. My advice to everybody else: find out what diamonds look like in the rough before you start digging!  A visitor from Wisconsin found a "flawless 5.47-carat, canary yellow diamond" there last month. Lucky she was digging at the only diamond mine in the world that lets the general public dig for diamonds and keep what they find!

MAKE a diamond?  What are you, Superman?\n\nThe reason diamonds are so expensive is because they cannot be made easily.  The amount of energy required to make a tiny little diamond far exceeds the potential value of the diamond.  That's why you don't see anyone making them.\n\nAt this point in our technological advancement, we have the ability to make nearly everything.  But it's usually not a question of "Can we do it?" but "What's the chepeast way to get it?"  Right now it's cheaper to find diamonds in the earth than it is to make them.

Well, if you have an idea of how much 163\nis, then consider what a million times\nthat would be.  Then take that number, and\nmultiply it by another million again.\n\nSo it's 163 million million.\n\nIt's a big number.  Consider that the Gross World Product\n(ie. the value of everything produced by every person\nand company on earth) is around 40 to 50 trillion\ndollars worth.  So 163 trillion is 3 or 4 times that.

If you're looking for a real diamond, but man-made, the newest thing is called "cultured diamonds".  They are grown in a lab and apparently are actually diamonds, just man-made.  Three companies make these, which you can look up on Google.  They are Apollo Diamonds, Gemesis and Chatham.

Diamonds are plentiful. The reason why the price is so high is because there are very few "families" that actual run the diamond mines. The DeBeers (not sure of spelling) family is one that basically owns 99% of the diamond mines in South Africa. They have gone to great lengths to make sure they are one of the few diamond brokers in the world. Great lengths is an understatement, for much of what they have supposedly done would be illegal if these mines where in the US. It's basically a "turf war". That said, diamonds aren't rare nor precious. \nAs for price, you can find cheap diamonds but the cheaper...the less "perfect" in the three C's. Clarity, Cut and Carat (don't quote me because the last C always gets me). \n\nDon't waste a dime unless you plan on dropping big coin on a perfect stone.

The value of stones depends on their rarity and esthetical value, not so much on their age. \nSecondly not all stones are as old as the earth. The earth's continental crust is continuasly renewed. New crust forms at mid ocean rifs and wells up in vulcanoes. And crust disappears when one continent al slab slips under another.

Diamond is one of the two best known forms (or allotropes) of carbon, whose hardness and high dispersion of light makes it useful for industrial applications and jewelry (the other equally well known allotrope is graphite). Diamonds are specifically renowned as a mineral with superlative physical qualities - they make excellent abrasives because they can only be scratched by other diamonds, which also means they hold a polish extremely well and retain luster. About 130 million carats (26,000 kg) are mined annually, with a total value of nearly USD $9 billion.\n\nThe name "diamond" derives from the ancient Greek adamas (αδάμας; "impossible to tame"). They have been treasured as gems since their use as religious icons in India at least 2,500 years ago—and usage in drill bits and engraving tools also dates to early human history. Popularity of diamonds has risen since the 19th century because of improved cutting and polishing techniques, and they are commonly judged by the "four Cs": carat, clarity, color, and cut. Although nearly four times the mass of natural diamonds are produced as synthetic diamond each year, the vast majority of synthetic diamond production remains small, imperfect diamonds suitable only for industrial-grade use, with gem-quality synthetic diamonds only recently becoming available.

DIAMONDS AND CHOCOLATES.

Retail value will be around $25k. However, this is rough since there is not nearly enough information to give an accurate assessment of your diamond.

I know the answer. One word. DIAMONDS. lol

diamonds are made of carbon.\nA diamond is a transparent crystal of tetrahedrally bonded carbon atoms. Diamonds have been adapted for many uses because of the material's exceptional physical characteristics. Most notable are its extreme hardness of diamond, its high dispersion index, and high thermal conductivity.\n\nThere form under extreme heat and pressure.\nDiamonds are formed by prolonged exposure of carbon bearing materials to high pressure and temperature. On Earth, the formation of diamonds is possible because there are regions deep within the Earth that are at a high enough pressure and temperature that the formation of diamonds is thermodynamically favorable. Under continental crust, diamonds form starting at depths of about 150 kilometers (90 miles), where pressure is roughly 5 gigapascals and the temperature is around 1200 degrees Celsius (2200 degrees Fahrenheit).\n\nWhere are they found?\nHistorically diamonds were known to be found only in alluvial deposits in southern India; India led the world in diamond production from the time of their discovery in approximately the 9th century BCE to the mid-18th century CE, but the commercial potential of these sources has been exhausted. The first non-Indian diamond source was found in Brazil in 1725. While no commercial diamond production exists in the US, Arkansas is the only state to have a verifiable source of diamonds. Today, most commercially viable diamond deposits are in Africa, notably in South Africa, Namibia, Botswana, the Democratic Republic of Congo, Angola, Tanzania and Sierra Leone [5]. There are also commercial deposits being actively mined in the Northwest Territories of Canada, Siberia (mostly in Yakutia territory, for example Mir pipe and Udachnaya pipe), Brazil, and in Northern and Western Australia. Diamond prospectors continue to search the globe for diamond-bearing kimberlite and lamproite pipes.\n\nWhat are they used for?\nThe dominant industrial use of diamond is in cutting, drilling, grinding, and polishing. Most uses of diamonds in these technologies do not require large diamonds; in fact, most diamonds that are gem-quality except for their small size, can find an industrial use. Diamonds are embedded in drill tips or saw blades, or ground into a powder for use in grinding and polishing applications. Specialized applications include use in laboratories as containment for high pressure experiments (see diamond anvil), high-performance bearings, and limited use in specialized windows.

yes. worked down there and found a two karat  and got it for 500 dollars. the catch is it is considered blood diamonds. due to the way they get the diamonds. and cant get it insured.

No, No, remember....Diamonds are a girls best friend :)

That's about to change! The cost to manufacture synthetic diamonds is continually going down to the point now where the diamond mining companies are getting worried, especially since the "imitation" diamonds are more perfect than the real thing!\n\nBut we can't say the same thing about gold. Nobody knows how to make gold yet and it's currently over $600 an ounce and going higher.

According to Ian Flemmings (the creator of James Bond):  Diamonds are Forever.\n\nI know it sounds like a cop-out, but I don't think diamonds degrade, so in theory, they SHOULD last forever.
