Has somebody try to make artificial diamonds?

Question

I've heard you get carbon on pure state and heat it... then let it cold slow

Can any type of carbon be used????

Answer 1

artificial diamonds have been around for a long time... they are used on diamond tipped saw blades and things like that. however, very recently i read something that said scientists have developed a technique to produce diamonds artificially that would be large enough for use in jewelry. the article also said that they would be able to control the color and clarity, essentially making a better diamond. also, artificial diamonds are structurally identical to naturally formed diamonds... it would be impossible to tell them apart, aside from the imperfections present in natural diamonds. and finally, diamonds are no more rare than any other gemstones, the increased cost is due to the fact that more than 90% of the diamonds mined each year are purchased by DeBeers and only a limited number are offered for sale.

Answer 2

Yes, it is being done. Synthetic diamonds are not worth as much as natural diamonds, though. And they can be spotted by a professional with a good eye and good equipment.


Can any type of carbon be used? Lol... are you planning on making a diamond lab in your basement? That's kinda funny. Carbon is usually carbon-- i didn't know there were many kinds. Even if you'd have the "right" kind, I'm sure you'd need all sorts of sophisticated equipment and conditions to actually make a diamond.

Answer 3

People would melt iron with large amount of carbon added to it (any "kind" of carbon would do) to make a saturated solution. On cooling, the carbon crystallized within iron to form diamonds, but of very small size. The diamond powder was separated by digesting iron with an acid.

Nowadays, there are sophisticated metal formulations to dissolve carbon (and other components that make diamonds colored). A small diamond is placed in such molten metalal as a growth seed, pressure apllied and after a couple days of here you go... a diamond of a carat size (usually yellow- brown from contained nitrogen)

Answer 4

Human-made diamonds have been around for some time. They are produced with carbon-12 by applying extreme pressure. Under such pressure, C2 double-bonds break and create a network of C single-bonds in the three-base pyramidal shape. Diamonds are so hard because of this shape. Rather than individual molecules, all the atoms in a diamond bond in the three-base pramidal form to create a rather large molecule that we call a diamond. the organized pyramdal arrangement of carbon-12 atoms allow light to pass through quiet easily, giving the diamond transparency and a high critical angle of reflection (makes the diamond sparkle).

Natural diamonds are impure. They have other substances in them, which sometimes gives the rock color (most particular: the pink diamond). The impurities decrease transparency and decrease the angel of reflection -- a less perfect diamond. Man-made diamonds are almost purely C-12. They are perfect in shape and structure. Man-made diamonds are of better quality, yet they are worth less. Why? Because it's easier to produce a perfect diamond in the lab than to dig a tunnel downward for a flawed natural diamond.

But would you really want to pay more for something less? Most people would, because they assume more expensive, natural diamonds are prettier.

Answer 5

YOU need to put carbon under a lot of heat an pressure to make synthetic diamonds. They are hard, but you can't make the big crystals like you can find with diamonds, so they are not nearly as valuable as the real stuff.

Answer 6

That's scientifically impossible. Diamonds are made of carbon, which is natural. No possible artificial material can compare to the hardness of diamond. Besides, it measures 10 in Moh's hardness scale. Nothing could be harder than that. Artificial diamond would mean fake diamond.

Answer 7

artificial diamonds have been mad for many years. pure carbon is heated & subjected to very high pressure.

that's a reason that people are trying to synthesize diamonds in the lab. two companies have been successful in this: gemesis and apollo diamond. google them online if you're interested, but apollo diamond is just starting up and is not putting out a large amount of products.

Answer 9

Yes. In fact there's a company that will now make a diamond out of your body when you die.

Answer 10

yes of course
molten graphite(an allotrophe of carbon) forms graphite under high temp and pressure
