I picked this pebble up in the grounds of Westgate Chapel when they had some road-chips delivered to fill-in the muddy bits, and the holes and dips in the drive. This caught my eye, so I brought it home with me and cleaned it up.
I've a long history of collecting these pebbles cut with quartz. Someone told me many years ago that they were 'wish stones'. You make a wish, and throw them, usually into water...moving water; a river, the sea. It's sitting on my kitchen window ledge, awaiting the right wish! Then I'll pass it on, for somebody else to catch the wish.
