A couple of days ago I picked this green pebble of the beach at Cley. It caught my eye because of its colour – I have never seen one like it here in Norfolk. I’ve had a look around on the internet and in a couple of pebble books that I own but can see no reference to a green beach stone. What can it be?
I’ve seen pebbles of a similar colour in Iceland at the edge of a glacier – but they had lots of little holes in.
The soft, but definite green, is similar to the roof tiles of some 1920’s houses – I wonder if it could be a sea worn tile fragment?
Serpentine rock from Cornwall is green, but I think this is too pale?
This pebble has similar qualities to other limestone on Cley beach – I wonder what type of rock it is and where it comes from. Any ideas?
