Cyclist at the Giro d’Italia are climbing the Alps for the last few stages before the arrival in Verona. As in other cycling tours, colored jerseys represent the leader in different categories… minerals are colored, too!

Some can even occur in different colors, due to the presence of impurities or microscopic inclusions of other minerals – that’s the case of quartz (SiO2)!
