A rock will never turn into a diamond regardless of time and pressure unless that rock happens to be a pure carbon rock.\n\nThere are many people now who have sytnthetic presses that can make diamonds (of various quality, usually not too pretty) in a relatively short time.\n\nThere is lots of information on the net and wikipedia has a decent article:\n\nhttp://en.wikipedia.org/wiki/Synthetic_diamond

Diamonds are the hardest naturaly occuring material on earth! On Mohs Hardness scale, Diamonds get a rating of 1500.\nAs an example, Quarts only gets a rating of 100.\n\nThe toughest thing a diamond can cut through is another diamond. \n\n.

Don't know if there is a rule of thumb but I'd say it would have to depend on how deep the diamond is so it wouldn't be simple math (area of a circle).  If the diamond is shallow, the face of it will look wide but it won't be as brilliant - the cut is important.  What you may want to do for comparison's sake is go on an internet site selling diamonds (loose ones) pick a couple 0.5 ct sizes in the shape you want (round = solitaire) and look at the dimensions... then pick a couple 1.0 ct sizes and check out its dimensions - that will show you the relative sizes to each other.\n\nAlso, with earrings - is it total carat weight or each earring?  If you have 1.0 tcw, each earring will be 0.5 cts.\n\nTo the guy below me: carats are a measure of weight (as described by the guy above me) - since diamonds are all made of the same stuff (therefore have the same density) the higher the carats, the more weight, the more volume, and the more volume, the bigger the size.  Of course number of carats correspond with size!  Cut is also important and will effect how big something *looks* but a 1.0 carat diamond will always be heavy (and therefore bigger) than a 0.5 ct diamond.

YOU MIGHT BE ABLE TO FIND IT IN THE DARK BY USING A BLACK LIGHT ? A DIAMOND WON'T WORK IN A CRYSTAL RADIO. IT TAKES A CRYSTAL, IT CONDUCTS ELECTRICITY, A DIAMOND DON'T CONDUCT.

I did a quick search on www.bluenile.com-\nThere were no diamonds which met your exact specifications, however the closest was a .24 ct E color ("D" is colorless), Internally Flawless (a grade below flawless), Ideal cut.  It was selling for $786.\nA .26 ct Good cut, D color, Internally Flawless stone was $610.

Diamond is (under normal pressure) a chemically less stable form of elemental carbon. In order to synthesize diamond, you need to expose carbon to huge amounts of pressure and considerable heat, as can be found under geological conditions.\n\nSynthetical diamonds aren't fakes, btw.

There is not.  Unlike gold/silver, diamonds are very abundant.  Their price is manipulated and controlled by DeBears.  I would not invest in any type of instrument such as you are describing.\n\nDebears regularly adds/subtracts from the market for specific types of stones depending on what challengers are trying to do.  Ie if a country tries to sell diamonds outside of Debear's pricing mechanisms/controls.  You could easily get killed with such an instrument.

Well is there Kimberlite in the mine? Is it ultramafic rocks formed at phenominal heat and pressure? No? Then you aren't going to find a diamond in that mine if you would have in the first place. There's a reason they're rare.\n\nAnd beeswax? Nothing. That's not going to help you unless you want to use it to stop up your ears to drown out the machinery noise. Actually that's a good plan. You don't want to loose your hearing.

This is strait from the book, My book "Gemstones of the World " by Walter Schumann.\n  The cutting of the colored stones is called lapidary work; the cutter is known as a lapidary. This can be the cutting of all types of stones and gems, from semi presious stones ( ie: turquoise )to the most pressious stones ( ie:Dimonds ) some times lapidary is refered to as a " gem cutter " or "stone cutter" but these are lossly used turms. \nUse the library for further reserch. A person that sells or deals in gem stons is a " gemalogist "

100% but they are such a low quality diamond that they are used in industry... they're typically very very small, discolored, and fragmented, not the type of stone you'd want to wear.\n\ncheers,\nkc

first of all do you know anything about diamonds?Do you know how to grade a diamond??Can you tell a real one from a fake??Do you have people or a place to sell your diamonds???There is a lot to know before you put your money or even your trust into a venture you are thinking about.

I have the princess cut and its MUCH more sparkley than the round one, Looks MUCH bigger, BUT... Costs more usually. If I had to choose I would keep my princess cut over any other cut out there, I think its the prettiest. I've never broken it... honey, Its a diamond. If it breaks that easily, its not real!
