If you are on the cusp of getting engaged, you are more than likely out searching for the perfect ring or necklace to give to the most important woman in your world! As you search you may become increasingly frustrated by prices and imperfections of diamonds you look at. It is often helpful if you know how this diamond got the jeweler in order to give it the acknowledgment for what it's worth. Here is a little bit about how the diamond came to where it is today, on her finger.

Millions of years ago, a single molecule, carbon, was pressurized deep within the earth's core. At least 200km under the surface carbon is under temperatures of 1300 degrees Celsius or more! These molecules then form a single cubic molecule that eventually, over time, creates a crystal. The diamonds eventually are pushed further up to the earths' surface by rare eruptions similar to earthquakes, where they can be mined.

First, consider this: the diamonds that are available today began forming millions of years ago, about 200km beneath the surface of the earth. Here, carbon molecules are under such intense heat and pressure that molecular cubics begin to form. The molecules then begin to crystallize and rise slightly to an area where they will stay until a volcanic eruption occurs. This eruption will send these materials to the surface of the earth.

Once the diamonds reach the surface, they are ready to be found and mined. Mining comes in many different forms, but the most widely used is called "hard rock mining.." Near where the volcanic eruption occurs, many tunnels and rooms are dug. Here miners are put under uncomfortable conditions in order to seek out diamonds. Once the diamonds are found they then go through a process of cutting and polishing. They are then transported to the gemological institute of America to be processed and certified. If the diamond is going to be used for jewelry, it will be cut again, facetted and polished and shipped to the jeweler.

So, now you know how diamonds got to where they are today! It took millions of years, manpower and technology to get that perfect diamond to that velvet box, appreciate your stone for what it is. And, more than that, you can quit griping about their prices now that you know what goes into getting them onto a band or necklace!

Diamonds are valuable to us because of the meaning behind them, regardless of whether a present or a symbol of a day. They have stories and moments that will make them irreplaceable.

However, there's a genuine, monetary value for your gem also. There are lots of stone graders which will certify and evaluate your diamonds to give you an idea of what your investment is worth. The acknowledged grading system for diamonds, established by the Gemological Institute of America, consists of the 4 C's. This process is utilized to decide the value of the diamond and separate it from others. Listed below is a closer look at the 4 C's.

* Cut - The cut of a diamond represents how well it is cut, which is graded from poor all of the way to ideal. The cut creates the brilliance that is so extremely coveted in a gemstone. A well cut diamond allows light to penetrate through the diamond and then bounce from one side to the other, reflecting out and creating a shiny, remarkable effect. At the same time, a poorly cut diamond does not permit light to penetrate and leaks light more than reflecting it.

* Carat Weight- A carat is a unit of measurement applied to the weight of a gemstone. For example, 1 carat is equal to.2 grams. Big diamonds are uncovered less often than small ones; therefore, the expense rises with the size.

* Color- Color is an assessment of the presence or lack of color in a diamond, which will not change as the diamond ages. Really few diamonds are truly colorless therefore the whiter a diamond appears the more valuable it is. Color is graded on a scale beginning with D, the maximum grade, and continuing to Z.

* Clarity- Clarity refers to the specific characteristics of a diamond. Imperfections and inclusions are the terms often used for the characteristics which are found in many diamonds. Blemishes happen outside the diamond, like scratches and chips, while inclusions are inside the diamond, like air bubbles and cracks. Grades for clarity range from F for flawless to Include 3, diamonds with heavy blemishes and inclusions. Diamonds with small or no flaws are the rarest along with the most valuable.

Your diamond has traits no other one has mainly because every diamond is special in its formation. Learning about these qualities will help you turn into well-informed when discussing your diamond's worth in case you take it to be certified or estimated.
