Those rocks are fossilized brachiopods. They were related to clams and other bivalves.
Sea-worn deck prisms? A couple of hundred years on the bottom being scoured by sea floor sand might make them look like that.
These things were more than likely made by somebody in their garage for $0.35. LOL
C'mon, get serious...they're the headlights off a U.F.O., duh!
Yes. I almost said brachiopods but I needed to double-check; it's been years since my geology studies. Brachiopods
Was it this?
Wally Lane's Coso geode
First, geodes are by definition hollow, so the item they found wasn't a geode. It appears to be an oxide nodule of very low hardness (Mohs 3) that encased a 1920s-era Champion sparkplug, probably discarded from an old mining operation. I've ruined my share of diamond saw blades, mostly because the item being sawed slipped loose in the rock vise resulting in a "dished" blade. None of the accounts I've seen says the blade was ruined because the nodule or its contents were too hard.
Vandalizaed cave formations? When caving I have seen translucent formations.
If they're pure silica, have no provenance, and were purchased (a mere three years ago), I'd say they're a modern artifact of some kind.
those rocks have exactly the same shape and consistency as my wife's fossilized poundcake muffins...
