Man Made

Concretion with Geode Cavity

Ferruginous Sandstone Concretion with Quartz Center

Metal Alloy (Likely Pewter or Sterling Silver)

Not a natural geological specimen; composed of refined metals. If pewter, it's a tin-based alloy. If sterling silver, it's 92.5% silver and 7.5% other metals (usually copper).
