This Smithsonite (analyzed) comes from the prolific San Valentín deposit. It is richer in crystals than usual and has a greenish hue unlike other smithsonites from there, which usually have brown tones. The fact that it is an old piece, from the French engineer Maurice Boudon, could be the reason for these differences from the more modern smithsonites. All this, and the pedigree of having belonged to Boudon, helped me at that time to decide to keep it.
