Karneol<\/a>\u00a0ist eine rote bis orangefarbene Variet\u00e4t des Chalcedons und erh\u00e4lt seine Farbe durch Eisenoxide. Das Mineral wird seit dem Altertum f\u00fcr Schmuck, Siegelsteine und Amulette verwendet. Die Farbe reicht von hellem Orange bis zu tiefem Rot, abh\u00e4ngig von der Eisenkonzentration und der Art der Erhitzung w\u00e4hrend oder nach der Entstehung.<\/p>\n Gro\u00dfe Vorkommen gibt es in Indien, Brasilien, Uruguay und Madagaskar. Karneol bildet sich in vulkanischem Gestein und Sedimentablagerungen. Seine chemische Formel lautet SiO\u2082 und er hat eine H\u00e4rte von 6,5 bis 7 auf der Mohs-Skala.<\/p>\n Beliebte Variet\u00e4ten sind der geb\u00e4nderte Karneol und erhitzte Formen, die besonders intensiv gef\u00e4rbt sind, aber von der Struktur her demselben Mineraltyp angeh\u00f6ren.<\/p>\n Quellen:<\/strong> Carneool Carneool\u00a0is een rood tot oranje vari\u00ebteit van chalcedoon en ontleent zijn kleur aan ijzeroxiden.
