How is the creation of jewels
Diamond is the hardest element exists on the ground and easier in the composition of precious stones and the circumstances that led to the creation of jewelery is not available on the planet millions of years ago, and since the first date of the globe and at the beginning of a turning material into the solid state has suffered material making up the core of the planet to degrees fictional pressure and temperature, and conditions in these deep layers are caused by the accumulation of carbon and the beginning of its transformation into crystals small crystals and turned into a diamond.
Diamond consists of pure carbon, and where there are no differences between the chemical characteristics of carbon powder and diamond but very large phenotypic differences do not compare.
When I started the earth’s crust in the cold exposed layers of variables, divisions and flows rocks liquid (Almajma) came under pressure and split in the form of lava and carried some of the material crystals diamond, which began in the formation depth of land and cold surface hardened diamond in the rocks and that there are diamonds in the rocks now.
The whereabouts of the diamond
We have most of the diamonds is currently in Australia Zaire Bonsuana Russia, South Africa and some parts of South America.
In general, it is prospecting for diamonds in the mines 20 Qatar distributed over four continents and most of the diamonds present in the places where the wing on the ground for the first time the focus has been to dig mines in these areas.
In mine, it is necessary to the normal digging and throwing dirt in a large area and an average of 250 tons of earth to produce one carat of polished diamond.
But most of the diamond does not exist in areas where the first terms caused the conditions of nature in the transfer of the diamond to areas far from their places of origin and must be removed hundreds of tons of sand to reach the rock layer and start drilling inside, and which may contain gems raw material which drifted to the sea because of the ancient river .
How to cut gems
When you find the raw stone is the way to cut off the top and the vital heart of the diamond must be cut
Every single stone and polished to make it a gem, a form typically have.
To get the highest return of the crystals are first separated from the process part chainsaw and a natural diamond particles, so when it is exposed to the diamond blade and roads in the right place Tnfelq it into two parts and most of the stones you need to publish some of them needs to be cut laser. But the deployment of the pieces is not only because every stone needs to be refined using the powder and polishing other jewels results in several aspects of surfaces and angles equal access to the best gloss Overall, the cutting and polishing is highlighting the brilliance of diamonds.
How do you deal jewels in the light
The way in which the diamonds shine in light is called brightness, glow, and these values ​​are not descriptive, but her scientific considerations.
Assuming that an equal amount of light falling on the mass of powder carbon as falling on a piece of diamond and two articles two components of the same raw carbon and its chemical properties, but they are clearly dealing with a beam of light in various ways, or is absorbed most of the light falling on the mass of powder carbon and therefore appear black .
But when the fall of light on the mass of the diamond is a reflection of part of the radiation on the surface and this so-called shine Aladaúa (a) and part of the optical packet enters the jewel and it is broken because of the optical density of the diamond is the so-called be broken.
And light reflected from the inner surface of the diamond is the so-called reversal of procedure (b), and then shows the beam from the top jewel and then broken again and spread to other colors, which gives the gem sparkle and glow.

How is the evaluation of Gems
The quality and value of diamonds on the four basic factors, namely:
1 pieces. 2 color.
3 purity. 4 carat weight.
Urgent and which meet the best of these elements are more valuable.
Details of the factors
1 pieces: You may have already been clarified pieces often, customers may confuse the quality of the diamond and the accuracy of the pieces in different shapes and forms the Marquis oval cone.
There are many shapes and weights of diamonds and affect the way the pieces on the quality and the quality and brilliance of diamonds glow and factors that affect the valuation.
The main forms of cut
1 round brilliant: This is the most popular form of all forms of polished diamonds.
2 oval: a form of adapter for the form of round and seem larger than the round shape of the same weight and carat.
3 Marquis: is the name given to a form of diamond jewelery is long Odhu edge at the ends of the two parties.
4 form the heart: it is the preferred form of romance and fantasy.

Emerald 5: It is the form of a cube with surfaces on each side and across the sides.
6 pear-shaped: the English name derived from the name the French series.
Color
Most diamonds appear colorless, but there are a lot of shadows and their differences seemed more urgent and without color of the greater value.

Because of different colors because of back what has been caused from the effects of high temperatures in addition to the pressure created when the diamond, where it mixes with the carbon atoms of the elements and the mixing effects are responsible for the color and so very rare to find the diamond without complications.
As a rare diamond colors and clear, the existence of this rare type of diamond and diamond-called French and brown and blue are the colors most appreciated.
Most of the gems appear colorless, but generally characterized by the impact of color and a predominantly yellow color due to the effects of nitrogen and the scientific method only to determine the color of diamonds is placing adjacent to a diamonds that have been determining the degree of color Sabquaokd the specification of a global evaluation of diamonds according to the difference in color and most of these standards from the Institute American Gems and Jewelry World Council of World Federation of jewelry and silver, pearls and precious stones.
Purity
Diamonds may appear within the impurities and that all crystals are especially at the beginning of the diamond may appear simple black raised or raised white light and fingerprints of these effects is called cross-cutting nature.
Number, size and location of any raised or fingerprints determine the degree of purity of the diamond and the less impurities and increased the value and effects of this are rare and there are international standards to determine the degree of purity of the specific diamond diamond boards already mentioned.
Gemstones.
Carat is the unit of weight of diamonds and weight is an important element in determining the value and carat is derived from the seeds of carob pulp or carob tree Gadihtoy the seeds of similar weight were used in this ancient grain from traders to weigh gems.
The diamond of equal carat weight of seed Khrnop In today’s world, the carat is equal to (0.2 grams) and each carat is divided into 100 points. Thus, a quarter carat equals 25 points in any (0.25) and a half carat is equal to two fifths of any point (0.50), it is easy and the weight of a diamond is diamond weight using the equations and the balance of certain private.
