Carneol
Carneol is a quartz and has got the hardness 7. The chemical formula is SiO2. Carneol does not form crystals like
Rock crystal or Amethyst does. He is red, because of admixed ferric linkages. These ferric linkages are ferric oxides, rust, so it is
clear why Carneol is red. He has got different red tones. It is easy to process this stone and so many engravings, sculptures
and other things are made of Carneol. In Egypt, Greece and Rome Carneol was well known and they thought that he has got positive effects. We can find this stone in anterior Asia and India. Today this stone is not so spreaded, but collectors like him very much.
