Au Bon Filon - Guillaume Mazankiewicz
Hello everyone, my name is Guillaume Mazankiewicz!
Passionate about mineralogy for 30 years and a geologist by training, I am originally from the Auvergne region in France; it is quite naturally there thatI started my prospecting and finds.
I specialized from the beginning in French mineralogy with a strong taste for fluorite! I criss-crossed the hexagon to discover the main French deposits and other more confidential ones; prospecting, photography of deposits and mineralization in place, discovery of crystals, this is my Ingres' violin...
In 2018 I created the aubonfilon website to make discover this aspect of mineralogy and to offer collectors a selection of French minerals from finds or purchases of collections.
I will regularly show you on this new site the latest acquisitions.
