black stone absorbs all light, no absorption is colorless (or white) and all absorption is black. The less light the gem absorbs the rarer and of higher value it is. Most of the called "colorless" diamonds have some inclusions and are not perfect transparent, but this inclusions often are only visible with a microscope.

A color diamond

means some kind of impurity, these impurities give a distortion to the light and the electrons jump to another energy level means certain light with a particular wavelength is absorbed and we see this as a color diamond.

An impurity absorbing wavelength of 560 nm brings this is in the green blue and purple spectrum brings a yellow color. Has the diamond an impurity in the 500 nm range green, yellow and orange are absorbed which finally means red color, the result is a blue diamond with a rather cyan shade. Just as fine contaminants can trigger the effect of color; it can also cause defects in the diamond structure, usually we see a combination of all together in this beautiful stones. Colored diamonds sometimes look much better than colorless stones, the question is how get the gem the colors? This can have several reasons. One of

the most common reasons for colored diamond are impurities trapped in the colored gem during formation, a other reason is the crystal structure of the color diamond, and sometimes the influence to radiation can all lead to different colors. If the come into contact with radioactivity some gems develop a green coloring. It might take about a million years or longer to form fancy diamonds. Spots or larger surface coloring can be removed during the cutting process.

Heath treatment of a diamond

with around 600 degrees Celsius might also cause a diamond to turn green. Higher temperature could turn the diamond stone into yellow or brown. Black diamonds are sometimes found in Brazil and the Central African Republic, they needs a very special environment with trace elements of nitrogen and hydrogen.

There are indications that black diamonds could have been formed in the space by carbon-rich cosmic dust and came to earth enclosed in meteorites, in those stones is no colored gem.

Pink diamonds comes in shades ranging from rose to purple. A pink diamond in particular from the Argyle Mine in Australia have been sold for even about $ one million per carat. Unlike usual diamonds which get their color from impurities embedded in the pink diamonds get the color by a process called plastic deformation.

A Pink diamond have only minimal nitrogen

impurities inside; they receive their colors by structural deformation by the intense pressure during the crystal growth. This changes the lattice

structure of diamonds and led a whole spectrum of red to pink. At blue colored diamonds, on the molecular level some nitrogen has been replaced by boron, boron reflects the blue light of the spectrum. More boron means more blue.

Yellow color means, some carbon molecules have been replaced by nitrogen, this will not alter the structure of the diamond but the clarity and color will be changed.

The amount of yellow color in the diamond depends on the amount of nitrogen.

Clarity of a diamond

is one of the main factors producing the fire and reflections of a diamond. The basic inside structure of a diamonds are prisms capturing the light and reflect it back and forth several times, before the light come off the diamond stone.

Clarity means how "clean" the diamond is. Clean diamonds have very few minor inclusions of gas, liquid, and minerals.

Inclusions cause an interruption

in the flow of light through a diamond and naturally the better the flow of light through the diamond is �minor inclusions- the better the clarity of that diamond.

Of course there are also other parameter such as cut and polishing doing the reflection and fire but the clarity is where an excellent diamond starts.

Inclusions interrupting the light flow

through the diamond can be very small, you probably can�t see them without a magnifying glass or microscope but they are there. If there are no inclusions in a diamond it is a lab created diamond called cubic zirconia. This created diamonds are grown in the lab and have a perfect clarity without inclusions, actually physically those artificial diamonds are real diamonds but they come from a different place. Inclusions make the gem look somehow cloudy.

Since most of the people cant look through this fancy diamond evaluation in a qualified way it is advisable to take an expert with you when buying a diamond, diamond ring, diamond earring etc. but don�t let the �expert� to move you into a particular shop, since he might have a friend there. You should go around and have a look to find what you like, after you get an diamond consultant, go back to this shop and ask him to have a look for the gem you like. This way you have a

good chance to get a good diamond buy.

Since more and more people see the beauty of color diamonds in jewelry such as engagement rings, bands, earrings and other precious items, growing demand in colored gems is the result. Especially color always plays an important role when buying all kind of body decoration, they also talk in terms of fancy diamonds this is an extended choice to the more normal white diamonds. Its different to the common precious stones the people usually buy. Those fancy stones won�t come less expensive, actually most are more expensive than other clear stones. Notable pink diamond, blue and green gems fetch higher prices.
We already indicated above why there is a color in the gem, because of inclusions of trace elements included in carbon during the creation of the stone. On the other hand it opens the way for manipulation since certain stones such as with brown color can be treated with heat to get a better and more clear shining. If it is told to the customer at the end that is are treated gems its ok since also the price is lower, but mostly the seller won�t tell, that�s a cheat then because after wearing the precious piece for a couple of years the gem will deteriorate somehow and this will be visible, after it has no value anymore.

A excellent option to buy some colored stones

with a small budget would be to purchase jewelry with synthetic colored diamonds also called CZ, this stands for
cubic zirconium which actually is physically a true diamond but made in the lab where carbon is pressed together under immense pressure to form the wanted stone, adding certain impurities during the process creates different shades.
Whatever gem you buy the basic evaluation parameter are color, clarity, cut and weight in carat. For fancy diamonds color is determined by the hue and the intensity, usually more intensity more expensive some diamonds have an additional basic shade which can intensify the overall color, shapes and cuts are more or less the same as with colorless stones.

Since the price of a particular diamond

jewelry gives a indication how good it is supposed to be, be very careful if someone offer you cheap jewelry, because cheap jewelry can�t be good.
