A diamond is crystallized carbon. It is the hardest known natural substance. Diamonds grow in the earth more than 150 kilometers deep in the mantle and their growth rate may be highly variable depending on the local abundance of carbon, the temperature, the presence or absence of melt, and other factors. Many of the diamonds found at the surface of the earth or in mines are very old, perhaps 3 billion years. Diamonds are mined in their rough form and then cut and polished to reveal their brilliance.

Diamonds, a form of pure crystalline carbon, are prized because they are the hardest of all known substances (rated 10 on the Mohs scale) and have high refractivity and brilliance. Today, diamonds are valued based on the 4 Cs: color, cut, clarity, and carat size. Many diamond imitations have appeared over the years, with the most common today being the cubic zirconia.
Crystallized Carbon. Probably the most recognized Gemstone in the world.
A precious gemstone composed of pure carbon. Hardest of all known substances, with a Mohs scale rating of 10.
Diamonds, a form of crystalline carbon, are prized because they are exceptionally hard and durable, have high reflectivity and brilliance, and because really fine diamonds are rare. Today diamonds are valued based on the "4 C's" of color, cut, clarity, and carat size. Many diamond imitations have appeared over the years, with the most common today being the ubiquitous cubic zirconia which appears similar to a diamond to the uninitiated, but can be readily distinguished by a diamond tester which measures thermal inertia. Trained individuals, despite claims of cubic zirconia manufacturers, also have little trouble distinguishing a genuine diamond when it is examined under at least ten (10) power magnifications.
A transparent stone. The true beauty of a diamond lies in its ability to separate light rays into all colors fo the spectrum and reflect these colors in a sparkling display. The value of a diamond is determined by its cut, color (or lack of color), clarity (or degree to which it is free of flaws) and carat weight. A diamond is the hardest substance known to man, measuring a full 10 on the Mohs hardness scale. Diamond is recognized as the birthstone for April.

Diamond is an isomer of carbon. The word diamond is often used incorrectly to describe a lozenge shape. The diamond in baseball refers to the infield or the whole pitch, so named because of its lozenge shape.
A precious gemstone made of highly compressed carbon deposits. Diamond is the hardest known substance.
A mineral that is composed of carbon with a hardness of 10 and that is single refractive. In its transparent form it is the most highly valued of gemstones. The stones can come in all colors of the rainbow and are called "fancies".
A crystal made up of 99.95% pure carbon atoms arranged in an isometric, or cubic, crystal arrangement. It is this unique arrangement of the carbon atoms that makes diamond look and behave differently from other pure carbon minerals such as graphite (the soft black material used to make pencils).
The hardest and most precious of gemstones, naturally white or colorless but occasionally found in yellow, amber, and other hues. Diamond is a crystallized carbon with unique reflective properties. See also cut, color, clarity, and carat.
Worn on the left hand, a diamond repels wild beasts and evil men. It's also a generally lucky gem, and insures fidelity in a lover.
A clear transparent precious gemstone composed of pure crystallized carbon which has been highly compressed over millions of years. Diamonds are the hardest substance known to mankind, rating a 10 on the Mohs scale. They are valued because it is difficult to produce a faceted diamond and when properly cut they have high refractivity and brilliance. The quality and value of a diamond is rated using the "4 C's" of color, cut, clarity and carat weight. (See individual listings). The diamond is the birthstone for April.
A diamond is the hardest known natural substance. It is crystallized carbon. Diamonds are mined in their rough form and then, cut and polished to reveal their brilliance.
A transparent gem made essentially of carbon which has crystallized under immense heat and pressure in the earth's crust. It is the hardest of all known natural substances. Hardness enables the diamond to be cut with precise accuracy.
The hardest substance known on Earth, made from a complex lattice of carbon molecules. Its rarity and legend make it one of the most sought after gemstones. Its name comes from the Greek ‘Adama', meaning ‘unconquerable' which symbolises love and eternity. See diamond pieces here
A natural and sythetic mineral composed of carbon atoms in a specific crystalline structure. Industrial diamonds include natural stones for tools to dress grinding wheels. Synthetic diamond is manufactured in a special high temperature, high pressure process and subsequently treated to make a variety of abrasive grains for use in grinding of nonferrous materials and ceramics. In its polycrystalline form, diamond also has a variety of uses including cutting tool inserts.
Diamonds are precious, lustrous gemstones made of highly-compressed carbon. Diamonds are one of the hardest materials known. Colors of diamonds range from colorless, yellow, orange, brown, to almost black. Rarer colors are red, blue, green, and purple; these colors (called fancies) are quite valuable. Canary diamonds have a deep yellow color. The largest-known gem-quality diamonds include the Cullinan (aka the Star of Africa, 530.20 carats), the Excelsior, the Great Mogul (an ancient Indian diamond which is said to have originally weighed 787.5 carats, but its location is not known and nothing about it has been authenticated), the Darya-i-Nur, the Koh-i-Nur, and the Hope diamond (named for a purchaser, Henry Thomas Hope).
(14th century, from the Greek word adamas, meaning "invincible ") A native crystalline carbon that is usually nearly colourless, although white, black and various pale shades of pink, yellow, red, orange, green, blue and brown are found. All good gem diamonds are transparent and free of flaws, and colourless stones, known as white diamonds, are extremely valuable. Considered the hardest substance on the earth, diamonds are also widely used industrially.
A mineral composed of carbon crystallized into a cubic crystal system by intense heat and pressure. It is the hardest of all natural substances (10 on Moh's scale). It ranges in color from colorless to yellow, brown, orange, green, blue, and violet. Reddish stones are extremely valuable.

Diamond is the hardest known natural substance and is composed of pure, crystallised carbon. Diamonds are mined in the rough form and are then cut and polished in order to reveal their fire and brilliance.
One of the three natural forms of carbon. The others are graphite and buckminsterfullerine.
Click Here to Search for Jewelry Using this Term Diamonds are the most precious stone. Millions of years old, diamonds are the hardest substance known to mankind, and are made from highly compressed carbon. A diamond's quality is generally rated in accordance with the Four C's:Cut, Color, Clarity and Carat Weight.
The hardest known mineral, composed of pure carbon; low-quality diamonds are used to make bits for diamond drilling in rock while high-quality are precious gems.
an isometric crystallized form of pure carbon, used as a precious stone and as an abrasive. The varieties used as gems are colorless. Diamond is the hardest natural substance known, ranking 10 on the Mohs scale. [AHDOS
A mineral composed essentially of carbon that crystallizes in the "cubic," or "isometric," crystal system and is therefore singly refractive. IT is by far the hardest of all known natural substances (10 on Mohs' scale); only manmade Borazon and synthetic diamond are as hard. In its transparent form, it is the most cherished and among the most highly valued gemstones. It occurs in colours ranging from colourless to yellow, brown, orange, green, blue, and violet. Reddish stones are known, but those of an intense red colour approaching that of ruby are excessively rare. Its hardness and high refractive index (2.417) permits it to be fashioned as the most brilliant of all gems, and its dispersion (.044) produces a high degree of fire. The specific gravity is 3.52. Sources include various sections of south, west, southwest and middle Africa; Russia; central, east and northeast South America; India; Borneo; and Australia. It is also found in the United State, but not in commercial quantity.
Mineral consisting of almost pure carbon in crystalline, which was formed under pressure and is the hardest natural substance known.
A precious gemstone composed of pure carbon. Hardest of all known substances. Rated 10 on the Mohs scale.
Diamond is the hardest known natural material (third-hardest known material after aggregated diamond nanorods and ultrahard fullerite), and is the more costly of the two best known forms (or allotropes) of carbon, whose hardness and high dispersion of light make it useful for industrial applications and jewelery. (The other equally well known allotrope is graphite). Diamonds are specifically renowned as a material with superlative physical qualities — they make excellent abrasives because they can be scratched only by other diamonds, Borazon, ultrahard fullerite, or aggregated diamond nanorods, which also means they hold a polish extremely well and retain luster.
