Know diamond from over eyes

todays price value of the some precious thing in among most of people's life are
Gold -1,536,35
Silver -41,34

As showing above we can conclud that the so much expensive and where the price go at all.The
amount of the incressing value is due to the current market sinario and lots of earn of gold and silver.
Thought gold and silver are the best option of investment but it is not quit possible to afffortable it for the
middle class people.So solution f the probleam of price probleam is useing diamond with the small amount
of gold and silver.Now a dayes people had so many crase to prchas diamond jewllery and why not diamond
have ability to full fill your requirement such as its shine,colour.etc

But diamond is not only just ornaments but it is also part of the the life of diomand makers.They make
diamond pristis and diamond make earning for them.

The mane moto of making this blog is not such that to introduce people with new brand of jewelries
and making mony by shaling and purchasing of diamond all that but introduse people to know how diamond
is part of the life in such indian people.

After visit this blog may know diamond is not beautifull but it is make beautiful by sprading life of
diomand makers.

Diamond

This article is about the mineral. For the gemstone, see Diamond (gemstone). For other uses, including the shape ◊, see Diamond

In mineralogy, diamond (from the ancient Greek αδάμας – adámas "unbreakable") is an allotrope of carbon, where the carbon atoms are arranged in a variation of the face-centered cubic crystal structure called a diamond lattice. Diamond is less stable than graphite, but the conversion rate from diamond to graphite is negligible at ambient conditions. Diamond is renowned as a material with superlative physical qualities, most of which originate from the strong covalent bonding between its atoms. In particular, diamond has the highest hardness and thermal conductivity of any bulk material. Those properties determine the major industrial application of diamond in cutting and polishing tools.

Diamond has remarkable optical characteristics. Because of its extremely rigid lattice, it can be contaminated by very few types of impurities, such as boron and nitrogen. Combined with wide transparency, this results in the clear, colorless appearance of most natural diamonds. Small amounts of defects or impurities (about one per million of lattice atoms) color diamond blue (boron), yellow (nitrogen), brown (lattice defects), green, purple, pink, orange or red. Diamond also has relatively high optical dispersion (ability to disperse light of different colors), which results in its characteristic luster. Excellent optical and mechanical properties, combined with efficient marketing, make diamond the most popular gemstone.

Most natural diamonds are formed at high-pressure high-temperature conditions existing at depths of 140 to 190 kilometers (87 to 120 mi) in the Earth mantle. Carbon-containing minerals provide the carbon source, and the growth occurs over periods from 1 billion to 3.3 billion years (25% to 75% of the age of the Earth). Diamonds are brought close to the Earth surface through deep volcanic eruptions by a magma, which cools into igneous rocks known as kimberlites and lamproites. Diamonds can also be produced synthetically in a high-pressure high-temperature process which approximately simulates the conditions in the Earth mantle. An alternative, and completely different growth technique is chemical vapor deposition (CVD). Several non-diamond materials, which include cubic zirconia and silicon carbide and are often called diamond simulants, resemble diamond in appearance and many properties. Special gemological techniques have been specially developed to distinguish natural and synthetic diamonds and diamond simulants.
