Hi, have just joined. What a great web site. I am trying to source some marbles we used to play with at school in England. We called they French Clays or Speckled Clays. Some were up to 2" they weren't very dense from what I remember (30 years ago) so not stone. All I have is a picture and not a very good one either I'm afraid. Please can you help identify them. There was a rumour that they were found on the beach locally, but I thought that was just a myth. They were quite numerous, so I'm guessing not antique or particularly rare, but I have searched the internet and can't seem to find. Please help identify. They were like a cream/yellow colour. More cream than yellow - the picture is not true colour. Thanks.
