Why are diamonds so expensive?

Actually, diamonds are not that rare.  How come you can always find them in stores?  The reason they are so expensive is the price is set by DeBeers, a private firm that has a near monopoly in the diamond market.  DeBeers hordes thousands of diamonds and only releases a certain amount each year to keep the market adjusted to their liking. Read up on them.\n\n(Looks like tripforyou beat me to the punch)

The reason they are called "diamonds" is due to their shape. The name Herkimer originates from Herkimer County in New York State from which they are mined.\n\nHerkimer diamonds are quartz crystals. The crystals are fully formed on both ends & are said to be doubly terminated. Sometimes they have smaller crystals sticking out the sides.\n\nQuartz is one of the most common minerals in the earth's crust & is made up of silicon & oxygen. The chemical formula is SiO2. Diamonds are made completely from carbon. The only carbon in a Herkimer diamond is the tiny bits of black organic matter found in them. These are referred to as inclusions.\n\nI have one in my classroom. Kids hear 'diamond' & go nuts. I hear, "How much is it worth??" When I tell them not worth much they usually lose interest. LOL

bcoz DIAMOND has the highest value of refractive index\n2.41\nany little amount of light present has to pass thru diamond \nso diamond glitters all the time

You can surely go to bluenile.com and check out the price of that specific ring if you want to have it made but you may also check into other jewelry stores.  The thing is that there are many variables when buying a diamond and you are talking about 5 diamonds mounted together, therefore you need to consider lots of variation in price and quality.  The best thing is to shop around, know what you can get with the price you want to pay, of course, it will be easier if you know someone in the field!  Hope that you will find what you want!

Getting an accurate history of diamond prices is difficult since different types have appreciated differently. I don't have estimates for 2005. If you  look at the 1st link (page 4) you will see that rough diamond prices have gone from ~1000 to ~1800 from 1980 to 2004, an increase of 80%. From the second link you can see the consumer price index went from 246.8 to 565.7, an increase of 129%.  Rough diamond prices have gone up less than inflation.  (I can't find comparable figures for cut diamonds, but they tend to follow rough prices.)  The next problem is that you buy retail and sell wholesale, and the wholesale price is often 1/2 of retail. (See third and fourth links) I don't think of diamonds as a good investment. (Except my wife likes the one I got her, so it was a good investment from that standpoint)

The jewels used in watches are usually rubies, sapphires (which are chemically the same as rubies), garnets and diamonds. After around 1900, most of the rubies used were synthetic. Before 1900, the jewels were either from stones that were too small or had too many flaws to be used in jewelry. In either case, they really weren't that costly. There is often a correlation between the price of the watch and number of jewels, but the jewels themselves are not the cause of this higher price. \n\nReducing friction is an extremely important goal in watchmaking. Jewels have two important properties that help reduce friction. First, they can be made to be very smooth, and therefore they let the metal parts slide easily. Secondly, they are very hard and therefore don't wear down very quickly. The gears in a watch are carefully designed so that the teeth roll on each other, rather than sliding. If the axle of a gear wears away the hole that it sit in, the gear will shift. That means the teeth will no longer roll on each other and therefore friction will be increased. \n\nThere are several different types of jewels used in a watch, the most common are: \n\nHole Jewels:   These are donut shaped jewels that fit over the gear axles (in watch lingo, the wheel arbors). \nCap Jewels:   These are flat jewels that are placed on the ends of the axles (arbors). \nPallet Jewels:   These are brick shaped jewels on the pallet fork that alternately engage and release the escape wheel. The escape wheel is the gear with funny "boot" shaped teeth. \nRoller Jewel:   This jewel is on the large balance wheel that swings back and forth. It engages with the pallet fork on the end opposite of the pallet jewels. \nThe jewels are carefully shaped so that the capillary action of the oil causes the oil to be drawn toward the gear arbors instead of spreading out where it doesn't do any good.

i do not know if there is specific reason.. i think cause of design and heavy of 18 carat gold... 4970 gr is not a reason, it is a result..

The most expensive gift I've ever recieved from a guy I was seeing was a diamond ring.  It was only .25 carots, white gold.  He was a drunken a**hole and after I had ditched him I gave the ring to a little girl I passed by at a fair because I felt it was bad luck to keep it.  ...I wonder if she still has it... No definately not still with him, really wouldn't mind never seeing him again.  :-)

why would you want to?  do you have any idea how many people have suffered over those diamonds????  buying them only perpetuates the conflict and makes the "bad guys" richer.  i was in sierra leone this summer and saw so many people with hacked off limbs and children whose parents were killed over those diamonds!  why don't you spend your money on something that does not support the slaughtering of innocent people!  i am not some crazy hippie either...  check out these websites\nhttp://www.hrw.org/reports/1999/sierra/SIERLE99-03.htm#P182_39824\nhttp://www.onesky.ca/diamonds/index.html

diamonds are just carbon atoms that are compressed so much that they become clear and shiny... theyre expensive because they are rare and very difficult to mine... they are often formed in places where there is a lot of heat and pressure such as deep down in earth... nobody knows where diamonds were first found cause they are so old that they date back to before there were and major written records

Lab diamonds (brand name diamonique) are chemically like diamonds from nature except that they are perfect, unlike natural diamonds which have subtle imperfections.  They are cheaper because, unlike their natural counterparts that take thousands of years and the perfect set of conditions to form,  man-made diamonds can be grown in hours/days (1 karat in 24 hours)....and it requires a lot less people, which means less paychecks.

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.

Life would be unrecognizable. Diamonds are the corner-stone (sorry for the pun) of modern high tec industry. They are used in everything from making cars to producing contact lenses, from heavy industry to neuro-surgery. In some applications they can be replaced by other hard materials but the equipment has to run slower and it wears out in a fraction of the time. All in all  much of what we  regard as "normal" today would not be here without diamond technology.

Just ask as opposed to ask with a HUGE diamond ring as an incentive?  Chances are much better with the rock in a box.
