A stone worth a bob?

Speaking of Bob, Bobert (name Bert and suffix -bert on a name means "bright and shining", you know, kinda like a diamond), Bobert! It ain't the stuff so much that gives it worth. It's how it's arranged! A Barbecue biscuit (brickette) or a graphite pencil has a lot more carbon than your average diamond. It's just not put together the same way.
