Misleading Photo
The picture is very misleading. The actual rock is a thin sliver about the size of my thumbnail. It's not worth a nickel, let alone the asking price.

Just a shard...
Honestly...yeah...it was obsidian....yeah....it was a decent color. It was just tiny. It met the 3 cm requirement only in one of the three dimensions. The other two were like 1 cm or 2 cm, making this essentially a tiny shard that is 3 cm long. I was very sad when I got it.
