Shameful actions indeed!
As shown in this thread, Mother Nature makes some stones. Sometimes she weathers them a bit round, Sometimes, Man interfers and cuts the stone, roughly or with precision to make edifices. And, sometimes Mother Nature herself cuts the sharp edge on a stone. Here is a gemstone I just got the other day of some Smoky Quartz with small white crystals of Pyrophyllite growing on it which exhibits that last idea of stone edge making. The mineral name for Smoky Quartz is Cairngorm which kind of makes it appropriate to accompany the towers, cairns, monuments and tombs already posted here, don't you think?
