Lapis Lazuli is not a crystalline gem like Amethyst is. Crystalline gems' structure is based on a particular shape, and even superficial damage to a crystal can send hidden cracks all throughout, even to the point of shattering. Wikipedia actually classifies Lapis Lazuli as a rock, having no particular structure. A crack on a rock doesn't make the structure any weaker than if the rock had formed in that approximate shape.
