Diamond
Is a component of a crystalline structure of cubical and unite and take multiple forms that construction of cubical eight-faceted, and in particular the twelve-face and mutations occur at times seems to be configured ball formation, but external factors can help in that configuration is composed of the element carbon only under the pressure and temperature wares and mysterious circumstances in the nucleus hemisphere, despite the fact that carbon is the main component of graphite and coal, but the characteristics are different from each other largely due to the atomic structure is not, but because of the network Alchristaip Diamond transparent and dark network of graphite. and similarities in the chemical composition is invited international companies to test conversion of carbon to Diamond and within the physical and chemical processes are complex and expensive place under the temperature and the keys high for a long time to convert the carbon into the circumflex Alchristali There are more than ten types of industrial diamonds famous (Almazinit), the most severe of diamonds or asymptotic his hardness, but not as monolithic structure is ( a compound of carbon with silicon components of what is known as silicon carbide). The age of the oldest Masa found from the age of Earth The most recent urgent about 5 million years ago, and carbon is the most known substances and with the benefit of the more than 3000 a discoverer of the day. Has been known since antiquity as one of the stones, the commercial value of religion. The increased popularity of diamonds in the nineteenth century with the increase in global production and improve the trade routes with the world and the entry of scientific methods in the cutting and polishing of the global monopoly of that commodity by some members of the companies. Diamond has many physical properties, but most famous is the hardiness and toughness alone on the degree of 10 \ 10 degrees in peace (MOS) World stones (Osalbha 10 - and weakened by 0) and sapphire is second only to diamonds and emeralds number 9 and the special crystal dispersion Alduulkn in diamonds are high to the light. For this reason, the diamond stone with a significant value in the jewelry industry as well as other industrial uses such as use of diamond drilling on the top tube wells, deep water, oil and natural gas in addition to its uses in electronic and medical devices, industrial equipment and others.
Pearl
Pearl is a secretion formed inside the steel ball by accident some types of molluscs and shellfish and is used as a cornerstone cream.

Emerald
Emerald: A form of beryl mineral salts, acquires a green color to the presence of trace amounts of chromium or iron, the Emerald of the gemstones, and compared the weights is the highest value among gems, especially when peppered with the veins of the other mineral salts, and salts Beryl hardness between 8 and 10 on the Moh scale of hardness materials. Aquamarine net is composed of aluminum silicate. Back to the green color to the existence of AIDS groups minutes of chromium in the crystals. The value of the Emerald in color and clarity of and free from cracks and purity of impurities.
In the Pharaonic times was a desert Nuba famous emerald mines, which were exported to the lack of emerald rulers of Persia, India, Byzantium, and discovered quantities of it in the tombs and temples in Mexico, Peru and Colombia were completely looted by Europeans, and the Emperor Nero loves Rumi Watch Wrestling slaves through the development of large emerald.
Most of the emerald crystals containing cobalt-minute sometimes called Lester. It also includes multiple exotic particles. The full emeralds are very rare, and if found to be more expensive than diamonds. And Emerald Blue Emerald expensive than a yellow.

Sapphire
Sapphire Gemstone Ohmrallon. Sapphire is different from the color red to light red color is caused mainly by chromium. Its name comes from the Latin for red rubber. Natural ruby rare, but synthetic rubies (sometimes can be manufactured relatively cheap. Other types of gem-quality corundum are to rubies. It is considered one of the four precious stones, with rubies, emeralds and diamonds. Rubies are mined in Africa, Asia, Australia, Greenland, Madagascar and North Carolina. are often found in Myanmar (Burma), Sri Lanka, Kenya, Madagascar, and Cambodia, but also in the U.S. states of Montana, North Carolina and South Carolina. Mogok Valley in Upper Myanmar has produced the finest rubies but, in recent years, the very few good rubies have been found there. The unique color in Myanmar (Burma) rubies is described as "pigeon's blood". It is known in the trade "Mogok" rubies. In central Myanmar the area of Mong Hsu also produces rubies. depository in Myanmar is situated in the Non-Aligned Movement Q. rubies in 2002 there were in the river and Waseges Kenya. Sometimes spinels are found along with rubies in the same rocks and are mistaken for rubies. But one fine red spinels may approach the average ruby in value. rubies have a hardness of 9.0 on the Mohs scale of mineral hardness. sapphire crystal was used for the production of manufactured the first laser.
