I spotted this in Joanne’s garden and thought it was just begging to be a PaD.
It is just 1 inch across and about 3 inches long, at first I thought it was
fossilised wood, but when I asked Joanne about it, it turns out that it’s a
piece of stalagmite or stalactite that was loose on the floor of a cave,
in Gibraltar. I’m going to polish the other end for her and will
probably post a shot when I’ve finished.
