Testing the hardness of rocks for Dremel carving

If you want to carve or engrave various random stones with a Dremel type grinder you will know that one problem is assessing the quality of the stone. This is the method I use, it is easy to put into practice and with a bit of experience you will be able to judge not only the hardness but also how gritty the stone is.
