The specimenI found was heavy and a very good example of kidney ore, in excellent condition, a fine piece indeed.
I doubt it very much if a collector lost it and never noticed it missing. I have been there again and have found no more pieces. I was talking to an old guy (from Tilberthwaite) who worked in the Horse Crag Mine and he could't even recognize the piece and said he had never seen anything like it around Tilberthwaite.
Just one of those strange things that happen now and then, strange indeed.
Thank you all for your comments on the subject, much appreciated.
