All 8 of these concretions were found in the country of Georgia.

These 4 are from China.

All of these are all from China.

I found this photo on e-bay. The rock was offered for sale as "0.8 lb Meteorite Specimen from Nandan, China!" The "Buy It Now" price was $295. It looks like a hematite concretion to me. Many hematite concretions start out as masses of cubic pyrite (iron sulfide) crystals that oxidize to hematite (iron oxide). That's what this one looks like to me.
