A number of years ago I was on holiday in Scotland and picked up (what I thought) was an unusual stone. It has two sides of approx 11cm in length at 90 degress to each other, with a third side of approx 16 cm in length. Looking from the 'top' it could almost be described as a triangle (although the bottom side is a bit ragged/broken(?)). The stone tapers down from the peak to bottom side. On the face of the stome are two etched lines in the shape of a cross, i.e. one of the lines is approx 10 cm in length and is parallel to the bottom side, and the other line interects the other line at approx half way along and is approx 4 cm in length. I only thought that the stone was interesting because I thought I had seen a similar stone in a museum somewhere. So....before I add the stone the rockery....has anyone got any suggestions as to where I could try and ascertain on the web where I could try and see if this is of interest (or just another rock).
