The toughness of a gem is how well a stone resists breaking and chipping. This is different from the hardness of a gem, which shows how well the gem stands up to the risk of scratches or abrasions. Diamonds are harder than they are tough. There are places in certain diamond cuts that are more vulnerable to chipping, such as the pointed corners of a princess cut stone. The pointed culet of the modern cuts of diamond are also more vulnerable than older diamonds (such as the Old European cut) where the culet was larger and finished with a flat facet. Today most diamond culets are finished in a point and must be well protected by their settings in a piece of jewellery to avoid becoming chipped.
