As we know, diamond is a kind of pure carbon in its most concentrated form. Diamond is made from carbon, completely is a chemical element of all life forms of the most fundamental problem there are some impurities like nitrogen, boron. Diamond is different from other close chemical as graphite and lonsdaleite Cousins, these two diseases are composed of the element of carbon. But what makes diamond unlike these close cousin is carbon atoms specially arranged it crystal structure. A crystal, as we know, is an entity, if formed from the connection of atoms elements or compounds repetitive arrangement. As you know, a crystal is an entity, with smooth face, the external blocks confined in the relatively small number of atoms are arranged to a simple numerical combination of elements.

A neutral carbon atoms can be composed of six protons and electrons that are arranged in its six surrounding the nucleus of atoms. A carbon atom electronic four valence, can form bonds and two hydrogen atoms. When we talk of graphite, the carbon atoms only three of the four covalence bond with their neighboring carbon cause a connection single carbon atoms flat leave these layers weakly connected to one another, and easy to use, they are separate is graphite so slippery. But in diamond, each carbon will share all four available electronic and adjacent carbon atoms so formed electronic key is the strongest known chemical links to a diamond its hardness. So repetitive structure unit diamond consists of eight atomic fundamentally arranged in a cube. So that the diamond crystals can appear in various shapes. So diamond crystals cube, octagonal, dodecahedra even comprehensive all shapes. These two kinds of special form, platform macle forms, it is actually a composite crystal and printing crystals, one has rounded surface, even slender shape.

The real diamond crystals may not have a completely smooth face. There may be slight produced impression on etching, natural crystal, dissolution, or part of the natural growth of crystallization. But a diamond may famous hardness, is that really resistance measurement of substance was scratched. So only a diamond can scratch another diamond. Therefore, we said that diamond is the hardest substance known to the nature. So hardness for its durability diamond may cause. Although diamonds are not fragile and easy to be broken, but it can also fracture or rupture. The answer is hidden in the perfect crystal structure. Because the structure of the diamond has some weakness in the plane can be split. A diamond have a perfect cleavage in all four directions so it will along this line of thought and tidy and not in the winding or irregular fashionable, because diamond crystals along the chemical bonds less than though other aircraft facial direction. Its function is to advantage for diamond knife. So in true form diamonds are concentrated form of carbon crystals.

There is an old theory that the earth is embedded in the sapphire earlier. This is the importance and the value of this stone. Sapphire is a very stones, as expensive diamond. Like a diamond, this stone is very hard. Sapphire although contact together is blue gems use many different colors, like purple, green, pink, white yellow. Sapphire like ruby belong to corundum family. Actually there are only two kinds of corundum – ruby is red, the other is sapphire by all other than the color red. Sapphire is a kind of mineral composition of existence of alumina, chromium, iron and many such elements have different tonal, the stone.

Sapphire is found in India, Brazil, Africa, Burma, Thailand, Sri Lanka. But the most famous varieties are sapphire from Kashmir in India, sapphire from Ceylon in Sri Lanka and blue sapphire found in Burma.

When a person talks of sapphire and common reference is blue gems. Blue variant is considered more valuable. However as mentioned they can use other colors. Sapphire colors like the pink, purple, green, yellow, white called fancy sapphires. These sapphire pricing less than blue. They are easy to mainly in the market is very easy

A rare variety of sapphire called star sapphire only in the designated place. This is a precious stone is half dome shape, reflects the shapes of light like six legs with stars. It is also called the cat’s eyes. Any jewelry by star sapphire as expensive car.

Sapphire can be evaluated from their cuts, complete, defect and thinking. Like other gems small defect is better gems. Because the sapphire is difficult gem cutting it is an art. However tool should take care of erosion and minimum and maximum arrangement reflection properties of the rocks. Stone color is the most important factor to be considered in the purchase of this stone. Deeper color more embodies the stone. Sapphire, can be in all tones are blue. The scope of different colors gray blue, shamrock, ocean blue and purple blue and many other colors. There is a wide variety of choice for customers. I understand that is wisdom to dark blue varieties. Sapphire color is also dependent on its places provide source.

Sapphire jewellery is very expensive. Have the sapphire ring is every woman’s dream but only few get lucky. Have chokers, pendants, neck down, bracelet, stud in jewelry store. Sapphire, or is used alone or in combination with other gems. They usually embedded in gold, silver and platinum. They are the most cost-effective sapphire in platinum. Sapphire looks very charming white gold is. This gem silver more than other pocket friendly basis varieties.
