| I looked at the grooves with a 10X jewelers loupe. The grooves across the face on the left look as if it was one or two passes in one direction only. The groove close to the right side had several passes back and forth. With slight smoothing. The groove is smoothed at the far edge which tells me the stone was smoothed at the far edge by sliding cordage off after that groove was cut in the stone face.There is some slight damage to the right side could the owner have been trying to slavage the tool by attempting to cut through it? |
