The sky is just a gigantic blue Sapphire stone into which the earth is embedded – this belief was cherished in ancient times. And, in fact, does there exist a better image to describe the beauty of an immaculate Sapphire of purest blue? This gemstone exists in all the shades of blue skies, from the deep blue of evening skies to the bright and deep blue of a clear and beautiful summer sky which charms all people. The splendid gemstone, however, also comes in many other colours, not only in the transparent greyish misty blue of far horizons, but also displaying the bright fireworks of sunset colours – yellow, pink, orange and purple. So Sapphires are really and truly heavenly stones, although they are being found in the hard soil of our so-called "blue planet”.
