What is diamond made out of?

Answer 1

Diamond is the hardest known natural material (third-hardest known material below 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 jewellery. (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.
The name “diamond” derives from the ancient Greek adamas (αδάμας; “invincible”). They have been treasured as gemstones since their use as religious icons in India at least 2,500 years ago— and usage in drill bits and engraving tools also dates to early human history. Popularity of diamonds has risen since the 19th century because of increased supply, improved cutting and polishing techniques, growth in the world economy, and innovative and successful advertising campaigns. They are commonly judged by the “four Cs”: carat, clarity, color, and cut. Although synthetic diamonds are produced each year at nearly four times the rate of natural diamonds, the vast majority of synthetic diamonds produced are small imperfect diamonds suitable only for industrial-grade use.

A diamond is a transparent crystal of tetrahedrally bonded carbon atoms. Diamonds have been adapted for many uses because of the material's exceptional physical characteristics. Most notable are its extreme hardness of diamond, its high dispersion index, and high thermal conductivity.

Answer 2

A diamond is one of the three known allotropes (different kinds) of Carbon. There are two ways a diamond can be made: naturally or synthetically. They can also come in many different colors. A diamond is an isometric-hexoctahedral crystal of Carbon atoms. Naturally, hey are created when trapped pockets of Carbon gas deep inside the Earth is compressed to extremely high pressures and subjected to very high temperature. Eventually, the intense pressure is enough to compress the gas into a solid crystal and the diamond is formed. Over the next few million years, volcanic pipes (not volcanoes) push the stones up to the surface of the Earth. If the diamond was created synthetically, it is essentially the same process. However, the creation of a synthetic diamond does not achieve as high of temperature or pressure and as a result the stone looks different when viewed under a ultraviolet light. The process is just injecting Carbon gas into a creation chamber at incredibly high pressures, then heating the gas. A colored diamond is created when a small amount of another gas makes the Carbon impure. For example, Nitrogen impurities will make a yellowish color.
