The diamond is regarded by many as the “ultimate gemstone”. Buying diamonds is always a good investment. One does not have to worry about depreciating values resulting from scratches and cracks due to exposure to heat and other causes of damages.
Diamonds are the hardest substances produced by nature. Among all the minerals, diamonds are the only substances which have the perfect 10 rating in the mineral hardness scale. This gemstone is four times harder than the sapphire which scores 9 in the scale.
In addition to being extremely hard, Diamonds are fancied by many because of their broad color range, high refraction, low reactivity to chemicals, and rarity. With a melting point of 3,820 Kelvin, diamonds are also very resistant to heat.The only flaw of a diamond is its perfect cleavage. Having four cleavage planes, a piece of this mineral would split or cleave when receiving a sharp blow in the direction of the grain on a cleavage plane.
