The hand of history is sometimes cruel. After enjoying status as an international diamond trading hub, Goa is now concerned about turning into a major coal importing hub in Indo-Pacific. Since there is a lot of attention to coal in local public discourse, people have forgotten the position of Goa in a related commodity- diamonds. Diamond and coal offer stark contrasts.
Diamond and coal are allotropes of carbon. Diamond is defined as a glimmering glass-like mineral that is an allotrope of carbon in which each atom is surrounded by four others in the form of a tetrahedron. Coal is defined as a black rock formed from prehistoric plant remains, composed largely of carbon and burned as a fuel.
