All that glitters

I've had a lovely weekend with my mum, dad (Cradlehall), F, my brothers and C in Bracklesham Bay. I fully intended to show you blips of the area, but leaving my camera battery at home was a big set-back. Oh well! Here's a piece of treasure I found on the beach this morning. I've no idea what kind of mineral it is, but it glitters nicely.
