These precious stones are found in many different colors such as; pink, blue, red, yellow, green, brown, purple, orange, gray, black, violet and even fancy white. Fancy loose diamonds can appear either as one primary color or one with a secondary hue. When the colored stone appears as a single color, the price is much more expensive. An example of one with a secondary hue is a pink diamond with an orange hue or a fancy color of brown, green and yellow, or a grayish blue diamond.

After these diamonds have been classified, these natural rough rocks are certified in a gemological institute such as GIA, HRD, and IGI. Once a stone has been graded and certified the natural loose diamond will have it’s own ID number. Measurements of the loose diamonds, diamond weight, diamond shape, clarity, polish, symmetry, and it’s fluorescence are recorded with the diamond ID. Colored diamonds come in all cuts, including: princess, oval, marquise, heart, pear, radiant, asscher, emerald, cushion and round.

The diamond price is reflected by these categories: color, cut, clarity, and carat cut. Colored diamonds are polished in a way unlike your common white diamond. On these diamonds, the color needs to be emphasized as much as possible. The grading system for colored stones, unlike white diamonds, go by color intensity. Fancy diamonds are graded by: light, fancy light, fancy, fancy intense, fancy deep, fancy dark and fancy vivid. The stronger the color the higher the price, and this goes for all Fancy Colored Diamonds.

Pink Diamonds have been the most popular of the colored diamonds. Fancy vivid and Fancy dark are the most adored and therefore the most expensive. Red, purple and orange are the secondary hues found in pink diamonds and the color in these natural pink rocks are caused by a process called plastic deformation. Pink stones play the role of cupid among the colored diamonds.

Blue Diamonds can be bought in a varied selection of shapes and intensities. They are usually certified by GIA or IGI. Loose blue rocks are extremely rare and as a result, their prices are very high. Fancy blues are completely natural and are classified as either gray-blue or green-blue. The color in gray-blue, grayish-blue, blackish-blue, or black-blue rocks are caused by the presence of small amounts of boron in their molecular structure. Green-blue or greenish-blue (teal) colored diamonds usually contain nitrogen impurities in aggregate form.

Diamonds are the symbol that we use to show are undying love for someone. They are the traditional icon of romance and love. Most people may be surprised to learn that the majority of diamonds that are mined today are used for industrial purposes and not for jewelry.

Historians believe that diamonds may have first been used for industrial purposes not for their brilliant sparkle and allure. Peter Lu a Harvard physicist and his colleagues discovered that in the late Stone Age the Chinese used diamonds to polish ceremonial burial axes. Today about 80% of mined diamonds are used for cutting, drilling, grinding and polishing.

Most people might be surprised to know that diamonds are not the hardest substance on Earth. Diamonds are the hardest natural mineral substance, but they are not the hardest substance known to man. A substance called Aggregated Diamond Nonorods is about 11 % harder than a diamond.

The first diamonds were discovered by Indians over 3,000 years ago. Diamonds didn’t get associated with love and romance until the 1940′s when the De Beers Company began to advertise diamonds as the perfect item for a wedding or engagement rings. They did an all out media campaign and soon people were buying diamond engagement rings all over the world.

It is believed that most diamonds are over three billion years old and most are formed more than 100 miles below the surface of the earth. Before the sixth century, India was the only known source of diamonds and was the predominant source for over 2,000 years.

The Romans believed that diamonds had the power to ward off evil and wore them as talismans. It is believed that they inherited this belief from Indian mythology. In France in the thirteenth century it was decreed that only the king could wear diamonds.

The Gemological Institute of America was founded in the 1950′s. It was the first internationally accepted diamond grading system. This system applied uniform criteria to grading the quality of polished diamonds. The GIA Gem Trade Laboratory Diamond Grading Report is the benchmark for the international gem and jewelry industry.

The Cullinan diamond was the largest rough diamond ever found and was 3,106 carats. It was discover in the Premier mine of South Africa in 1905.It was cut into nine major stones. The largest of the stones is the Star of Africa and is 550.20 carats. It is housed in the Tower of London and mounted in the British Royal Scepter. The most recent diamond discoveries have been in the Northwest Territories of Canada and in Colorado. Explorers found diamond pipes in both locations in 1990.

It wasn’t until the late 13th century that diamonds were used in European jewelry. Diamonds were initially used for engraving other gems including sapphire cameos. They were also used for drilling holes in hard stone beads.

Diamonds have been around forever and are cherished by all. Diamonds have an exciting and lively history. These are just a few of the fascinating facts associated with diamonds.

About diamond testing nature or nonsense ?

I have a therory, regarding natural rough uncut diamonds .I believe they can be tested by using the sun . If you hold a diamond up and look inside the center of the sun at the hotest part ,of a cloudless summer day without being blinded it is a diamond.Remember (uncut). Due to the fact its refractive index is so high compared to all other gems while uncut it absorbs the direct rays of the sun sheltering your sight.

For heaven’s sake DO NOT DO THIS – it is the fastest track to BLINDING YOURSELF that you can follow, it is playing Russian Roulette with a gun that has six bullets in the chamber and none empty. A high refractive index has NOTHING to do with absorbing light WHATSOEVER, it merely indicates the degree to which light is bent while passing through the medium. In addition to this diamond is cubic and therefor singly refractive so it does not even absorb part of the radiation like many other stones.
It is true that with properly proportioned cut diamonds no light passes through the stone when viewed from the front through to the back due to its being totally reflected internally – this can also be achieved with other stones but the required cutting proportions are too deep to be practical. In the case of an uncut diamond you do not even have the minimal protection of it having having facets to internally reflect the sun’s light so it will go straight through and do permanent damage to your retina.
Once again please, please, for your own sake do not try this out. Excuse all the Caps. but this is a VERY IMPORTANT SAFETY MATTER.

They say they are ‘forever’ and, other than the sentiment supposedly attached from the bearer, ‘they’ are right in an elemental sense. Diamonds are the hardest substance known to man. On the Moh hardness scale (mineral quality scale used for identification and differentiation of minerals) it rates a perfect 10. The atoms of diamond are arranged tighter than in any other substance, giving the gem its hardness. A diamond can only be abraded by another diamond of higher hardness and diamonds are used to polish other diamonds.

The melting point of diamond is 3,820 degrees Kelvin, making it the highest melting point of any substance. Diamonds are tetrahedrally bonded pure Carbon atoms; they are terrific heat conductors and have a high dispersion of light making them ideal for industrial applications as well as jewelry. This ‘fire’ and hardness are considered the ideal reasons why diamonds are so typically interpreted as wedding or engagement rings due to their durability for everyday wear.

Diamonds are not particularly rare, although advertising campaigns and big diamond companies would have the public believing otherwise. There is a great deal of controversy surrounding the mining, sale and market value of natural diamonds. Approximately 50% of the world’s diamonds come from central and southern Africa with much of the sales of the gem being handled by paramilitary groups and are sometimes dubbed ‘conflict diamonds’ or ‘blood diamonds’ because of the tragic deaths which occur through the mining, sales and transport of these diamonds. Other areas in the world where diamond mines are prevalent are Canada, India, Russia, Australia and Brazil.

Diamonds have been brought to the surface of the earth from deep within the earth where extreme pressure systems and extremely high temperatures caused their original formation. Volcanic eruptions from 1,100 million -20 million years ago carried the diamonds through Kimberlite pipes to the surface of the earth. These pipelines were formed as magma flowed through intense ruptures in the earth. When these explosions occurred, the magma thrust the diamonds through the pipes, bringing them and other minerals rapidly through the mantle and crust without disturbing their structure by pressure or heat. There are some diamonds found on the earth today that are dated as old as one billion years.

Natural, uncut diamond crystals are formed in isometric cubes and octahedrons (8-sided prisms). Diamonds are rated as having high value by color, high refraction, fire (high dispersion), rarity and extremely low reactivity to chemicals. Diamonds can come in many colors including, yellow, brown, blue, green, black, pink, orange, red, purple and violet. The closer the diamond comes to perfect translucence and no additional hues, the higher in value it becomes.

A diamond of a pink or blue hue is also rated as quite valuable due to the rarity of these gemstones and the more intense the color, the higher the diamond is valued. The Hope Diamond, one of the largest diamonds in the world at 45.52 carats, is now housed in the Smithsonian Natural History Museum with an estimated value of $250 million dollars. Diamonds are judged by carat, clarity, color and cut- the ‘four C’s’ of Diamonds—and are valued and rated by these characteristics.

The Clean Diamond Trade Act, as the bill in question is called, concerns rough diamonds being sold in African nations such as Sierra Leone, Angola, and the Democratic Republic of the Congo. This traffic in gems has unforeseen consequences lying beneath the surface of the rough diamonds. According to the act:

“Funds derived from the sale of rough diamonds are being used by rebels and state actors to finance military activities, overthrow legitimate governments, subvert international efforts to promote peace and stability, and commit horrifying atrocities against unarmed civilians… against trade in conflict diamonds. (6) Without effective action to eliminate trade in conflict diamonds, the trade in legitimate diamonds faces the threat of a consumer backlash that could damage the economies of countries not involved in the trade in conflict diamonds and penalize members of the legitimate trade and the people they employ. To prevent that, South Africa and more than 30 other countries are involved in working, through the ”Kimberley Process”, toward devising a solution to this problem. As the consumer of a majority of the world’s supply of diamonds, the United States has an obligation to help sever the link between diamonds and conflict and press for implementation of an effective solution”

Sponsored by Representative Houghton from New York, This bill was passed in April or 2003. There are many regulations and oversight in the rough diamond trade to ensure that the sale and certification of gems coming from wholesalers and distributors are bona fide. What appears next is a parse of this bill and the conditions that pertain to it in systems theory:

Intrasocietal Environment: Sierra Leone, Angola, The Congo…rebels, politicians, refugees etal.

Extrasocietal Environment: Trade partners of various African nations, United Nations Security Council, Human rights and humanitarian advocates, the diamond trade as represented by the World Diamond Council, and the United States Government.

Disturbances: Rebel Militia actions against governments, refugee activity, slave laborers, United Nations reports, Advocate group intervention, moral fortitude of consumers, public knowledge, media coverage.

Inputs: House of Representative members Houghton, Rangel, Smith and Thomas, United Nations Security council reports, public awareness of the conflict diamond trade woes, World Diamond Council, advocacy groups, international preference against supporting rebels/militias/slave labor.

Demands: stop support of illegitimate forces in free nations, protecting refugees/general masses from inhumane treatment, protect the legal trade in rough diamonds, verify the source of diamonds.

Supports: UN Security Council, US House of Representatives, Senate, President Bush, U.S. Bureau of Customs and Border Protection, Kimberley Process, South Africa

Outputs: PUBLIC LAW 108-19-APR. 25, 2003, Clean Diamond Trade Act, international cooperation in an embargo of non-certified rough diamonds, UN pressure to stop the trade of conflict diamonds, “the United States implemented sanctions restricting the importation of rough diamonds from Sierra Leone to those diamonds accompanied by specified certificates of origin and fully prohibiting the importation of rough diamonds from Liberia.
