Trustworthy sand collectors with which I already traded :
Philippe Florimond (France - Vaucluse)
Sylvain Painchou (France - Vendée)

"A travel in space and time to discover the origin, the formation and the composition of sands of the world, and to share the fascination which they exert on the collectors."
