When visiting keep this in mind as you gaze at those shining diamonds – although the diamond is so hard, it is however easily broken; and indeed by a certain knack, it can even be cut with a common penknife.
This is due to what is called its cleavage, a direct result of the crystalline structure. It’s interesting that many well known substances such as slate, for example – split or cleave with peculiar facility in certain definite directions, while they offer considerable resistance to fracture in all others.
The diamond has this property, cleaving easily in no less than four directions, and parallel to the surfaces of the octohedric crystal; and therefore, when moderate force is put upon it in either of these ways, the diamond simply splits into pieces.
The cleaving property of the diamond does have its purpose though, firstly by splitting the stones when they contain certain flaws, and secondly, in the preparation of diamond powder.
Those shining diamonds that you see as you visit jewellers did not start out that way. When a rough diamond is seen to contain a defect that would depreciate its value as a single gem, it is spilt in two, precisely at the flaw, so as to make two good sound stones.
