I love this on so many levels (and thanks for the mention.) My father-in-law was a blacksmith in the iron mines of Michigan's Upper Peninsula a century+ ago, leading us to acquire 3 gorgeous Whistler blacksmith lithographs. That's a wonderful photo! I go with placing the stones in your garden, or barring that, any garden or seashore spot. They'll eventually return to the planet, as will we all; I think your noticing, and remembering, is the appropriate honor.
