Rough diamond?

It seemed unlikely to find a precious stone in the gutter of a street in Leith. And sure enough, when I looked a bit closer, I discovered it was a chunk of glass from one of those "real fire effect" gas fires.

Ah, the fascinating things you find on bin day.

Oddly enough, the guy in the distance gave me a wide berth when he passed me. But he almost walked into a bin, trying to see what I was doing in the gutter while pretending not to be interested.
