Only a few caves with green aragonite exist in the whole world. The most beautiful cave is in France! The green color is caused by the presence of small quantities of nickel minerals.

This cave is extremely fragile and (of course) well protected. It can only be visited by two persons at a time, taking all possible precautions not the damage or muddy the formations.

A visit to this "green chamber" is an experience that you'll never forget!

Amazing contrast between vivid green and snowwhite aragonite
