I just found this and it looks very cool. It has kind of a wavy look when there is a lot of light and it has some depth to it visually. Also it feels dense and weighs a lot given it's size. It's about an 1 1/2 inches long. I would compare its weight to the piece of lead of the same size if not heavier.
Take a look..
Maybe the pics don't do it justice but that's the best I could do.
