Where a diamond has a cleavage direction or a parting direction in twinned crystals the diamond will come apart more easily.
If a diamond in a ring falls say onto a floor would the parting suffer much small feathering which runs across the whole stone or would it cause the diamond to fall into different bits or would it suffer a chip at the edge of the parting?
How does the parting start to come apart?
