Sapphire comes in many colors: not only in the transparent blue, but also in yellow, pink, orange and purple.
Blue is the main color of this magnificent gemstone. Blue is also the favorite color of some 50 per cent of all people, men and women alike. The sapphire belongs to the corundum group, the members of which are characterized by their excellent hardness (9 on the Mohs scale).
Indeed their hardness is exceeded only by that of the diamond and the diamond is the hardest mineral on Earth! Thanks to that hardness, sapphires are easy to look after, requiring no more than the usual care on the part of the wearer.
