what's the average size of a diamond?

I would say 1/4 to 1/2.

The average diamond is approximately 3 billion years old. Some newer some older. Thats about 2/3 the age of the planet.\nDiamonds are not created in the earths crust, but rather deep in the earths mantle at about 1800 degrees F. The diamonds are brought to the surface by volcanic activity.

A diamond is a crystal structure, and thus, exists only as a solid.  If you melt or boil a diamond (at incredibly high temperature) it is no longer a diamond, but carbon.

4.5 - 6 inches.....so anything above 7 inches seems HUGE if you've only been with average ones...

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

Of a *****, the average size is ******

I will not do your homework for tou.\n\nDo a Google search on "refractive index" for both water and diamond. There is your answer.\n\n Come back if you have any points you don't understand. Asking other people to do your homework is not just dishonest and lazy it is really stupid.

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.

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!

I'm pretty sure it is a Diamond. Here's my reasoning:\nDiamonds family name = carbon = black in appearance\n"Give a girl a buck" = Diamonds are a girls best friend\nMany nice colors = Refraction of light through a diamond displays many colors.....

41 - 24 carats in solid gold\n\nMy mom loves doing these, but i'm not so good...

The four C's are used to determine a diamond's rarity and value, according to the Jewelry Information Group, a non-profit trade association based in New York.\n\nCut refers to the shape of the diamond and the number of its facets - or flat, polished surfaces. Each diamond cut should be precise to best show the stone's brilliance. A well-cut diamond reflects the light and refracts it back to your eye.\n\nClarity is determined by a diamond's internal imperfections and external irregularities, which interfere with the passage of light through the stone. Called inclusions, they can be spots, lines or bubbles. The fewer inclusions, the greater the value of the stone.\n\nCarat is a diamond's weight, not size, as many people believe. One carat equals 200 milligrams - the heavier a diamond, the greater its rarity and, usually, value.\n\nColor is also a value-determining factor. Diamonds can come in a variety of colors, but colorless stones are most rare and expensive. Diamonds are graded on a color scale, from D (colorless) to Z, established by the Gemological Institute of America (GIA). The further down the alphabet, the more yellow and less valuable the stone is.

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.

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

1 inch is 25.4 mm.\n\nI is roughly the size of the second bone of your index finger.  A US quarter has a diameter of 24.26 mm, so it is just under 1 inch, so you could use a quarter to make an estimate of distance if you needed to.

Closest I could find it the largest carved gemstone.\nIt is a carved sapphire, and weighs over 27 pounds (61,500 carats). http://www.guinnessworldrecords.com/content_pages/record.asp?recordid=47717\n\nLargest diamond is 545.76 carats (http://www.guinnessworldrecords.com/content_pages/record.asp?recordid=47736)
