P.S have you tried a rubbing?  holding a sheet of paper over the stone and rubbing over it with a thick black crayon or better still "cobbler`s heelball " black wax  for waxing  the strong thread  for hand stitched soles to you and me.You can get it in shops attached to Cathedrals for people who do rubbings  of the brass plaques marking graves in the Cathedral, of knights etc.
