Airoldi Giovanni started to collect minerals in 1967, after finding -to coincidentally- a splendid block of quartz dragon-shaped in Cervinia (Aosta).
The passion for mineralogy has been transmitted to his son Vittorio that has expanded in the study, cutting and collection of precious stones.
Currently Airoldi John and Victor have:
a collection of minerals that matters 1500 parts of which 70% the result of research and 30% arising out of the bag and exchange;
a small collection "Micromount" Vesuvius with 2500 pieces and about 130 variety;
a collection of precious stones (cut by themselves) from around the world, composed by 80 pieces.
