Diamond is the hardest naturally occurring substance present on earth. It is also one of the most precious substances in the world. Their surfaces are transparent and resistant to heat, making them highly useful in jewellery making and for industrial purposes. For example, after mining the diamonds, we can classify them into gem-grade diamonds, crushing bort and industrial diamonds. The gem-grade diamonds are most suitable for jewellery making.
Like metals and all other minerals, we can extract diamonds from their mines. A mine is an archaeological site from which we extract minerals and solid metals. From ancient times, India has been one of the significant sources of world-renowned diamonds.
