Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

Diamonds are made of a single element—they're nearly carbon. Under the immense heat and pressure far below the earth's surface, the carbon atoms bond in a unique way that results in diamonds' beautiful and rare crystalline structure. 5. The word diamond derives from the Greek word "adamas," which means invincible or indestructible.

One of the important differences between diamond and graphite is the way their molecular arrangement is made. In diamonds, each carbon atom is strongly bonded to four adjacent carbon atoms. Probably this is the reason behind its hardness.

Diamond is a solid form of pure carbon with its atoms arranged in a crystal. Solid carbon comes in different forms known as allotropes depending on the type of chemical bond. The two most common allotropes of pure carbon are diamond and graphite.In graphite the bonds are sp 2 orbital hybrids and the atoms form in planes with each bound to three nearest neighbors 120 degrees apart.

Asia - Asia - Mineral resources: Asia has enormous reserves of coal, amounting to nearly three-fifths of the world's total, but they are unevenly distributed. The largest reserves are found in Siberia, the Central Asian republics, India, and especially China; Indonesia, Japan, and North Korea have smaller but nevertheless economically important reserves.

Diamond is a well known allotrope of carbon. The hardness and high dispersion of light of diamond make it useful for both industrial applications and jewelry. Diamond is the hardest known natural mineral.This makes it an excellent abrasive and makes it hold polish and luster extremely well. No known naturally occurring substance can cut (or even scratch) a diamond, except another diamond.
