When rocks are the crowning achievement of your civilization, you take what you can get.

Take my word for it, these rocks as you call them are far more efficient than any fingernail clipper you can buy in stores.

The key word is 'alleged.' They may not actually be artifacts but rather were presented as such to fool gullible collectors. What is on display may be a confidence trick that could sell for millions if the seller can find a good victim.

also abos: "muh stones!"

Lol.
