The top side has a circular border area (5), whose breadth ranges between 10 millimeter and 30 millimeter. Side walls (4) are arranged at 90 degree angle to an upper side. The height of the side walls ranges in between 0.5 millimeter to 2.0 millimeter, where the height of the side walls is less than the height of the stone.
