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 (radiation exposure), 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 developed to distinguish natural and synthetic diamonds and diamond simulants. From Wikipedia under the

From Google Video Search: "clearest diamonds" What do you think about an engagement ring with a colored stone? Q. Would you prefer a clear diamond or CZ, or a colored stone, pearl, etc? What color would you like? Asked by falling.from.grace - Fri Jun 17 16:48:30 2011 - Weddings - 17 Answers - Comments A. I preferred a colored stone and that's what I got. It's a green sapphire, one of the most rare kinds. It has two clusters of diamonds on each side in a diamond shaped setting. Kind of art deco style. What I love about colored stones is that you often can afford a bigger colored stone for the same price as a smaller diamond. Also our jeweler told us that colored stones are more common than diamonds in Europe. Also, my jeweler, and many others I have met usually say the same thing: I like diamonds as accent stones, they are kind of boring as center stones. That's how I feel about them. I just felt like getting a diamond was kind of allowing myself to be duped. Sort of like how I wanted a pair of designer sunglasses for SO LONG. I finally… [cont.] Answered by BloopieBlooper - Sat Jun 18 02:27:59 2011 i found a rock with clear stones growing on the rock how can i tell if it is something real like diamonds?
Q. Found a rock is it diamond crystal glass Asked by Connie - Tue Jun 1 13:05:34 2010 - Poetry - 1 Answers - Comments A. They are probably just geodes. Did you find it above ground? Diamonds have to be mined, and are a result of years of high pressure and heat. Answered by Slayer126 - Tue Jun 1 13:29:13 2010 From Yahoo Answer Search: "clearest diamonds" |
