The nature is very changeable and mysterious. Every moment in the subsoil of the Earth go on different physical and chemical processes, most of which people can never comprehend. One of them - formation of the fanciful-shaped molecules that make a base for semi-precious stones and gems. My hobby is studying of stones.
 From the time immemorial people believed that stones might serve as talismans.They were considered to be  connection between gods and humanity, they contained  a vivifying energy that could treat any disease. Every stone bears very powerful energetic fund: it can injure to people or help them: bring luck, attract money or even contact with next world.
 I have many favourite stones and I`ll tell you about them from time to time.
The first one is Lapis lazuli:

This opaque, deep blue gemstone has a grand past. It was among the first gemstones to be worn as jewellery and worked on. At excavations in the ancient centres of culture around the Mediterranean, archaeologists have again and again found among the grave furnishings decorative chains and figures made of lapis lazuli – clear indications that the deep blue stone was already popular thousands of years ago among the people of Mesopotamia, Egypt, Persia, Greece and Rome. Particularly in the Middle East, it was thought to have magical powers. Countless signet rings, scarabs and figures were wrought from the blue stone which Alexander the Great brought to Europe. There, the colour was referred to as 'ultramarine', which means something like 'from beyond the sea'.
 Lapis lazuli is regarded by many people around the world as the stone of friendship and truth. The blue stone is said to encourage harmony in relationships and help its wearer to be authentic and give his or her opinion openly.
Lapis lazuli is an opaque rock that mainly consists of diopside and lazurite. It came into being millions of years ago during the metamorphosis of lime to marble.
 Uncut, lapis lazuli is matt and of a deep, dark blue colour, often with golden inclusions and whitish marble veins. The small inclusions with their golden shimmer, which give the stone the magic of a starry sky, are not of gold as people used to think, but of pyrites. Their cause is iron. The blue colour comes from the sulphur content of the lazurite and may range from pure ultramarine to a lighter blue.
