While walking my dogs this morning I spotted a piece of pinky coloured quartz sticking out of the ground. After a couple of nudges with the foot it come free, it was about the size of a cricket ball. When I got home I run it past the detector and the bloody thing went crazy. Whoopee I thought, so I broke it up and put the detector over it for no sound at all. The first time I run it past the detector it had sounded off on my wedding ring. Pmsl, what a dickhead.
