Sapphire is a gem. In jewelery, all shades of corundum stones are considered sapphires, except the red ones, which are rubies.

Sapphires are a reflection of endless sky, purity of mind, and the ability to see the essence. Sapphire helps to get rid of laziness; it is a gem of contemplation, wisdom, and perception.

And with no doubt it is a symbol of unselfishness and eternal friendship.
