Blue Mosque

Marble is commonly used as a decorative stone in buildings and few buildings are even entirely made out of marble. The mihrab, columns in the Sultan Ahmed mosque in Istanbul are made of finely carved white marble. Most marble is white, but impurities can change its colour from anything from dark grey and greens to bright pink, red and yellows. In ancient times you could easily tell a marbles origin by looking at its colour.
