Something I forgot to post. A couple of years ago a Jeweller friend asked me if I could shape a piece of stone from a church wall. He hinted that it may have a royal connection and that was it. The stone was from St Michaels church wall in Newhaven. I then found out it was for a Brooch for H.R.H Princess Anne.
