Granite Worktops are not indestructable, though sometimes worktop salesmen can overstate the properties of certain granite materials. Different types of granite do vary as to how easily they scratch or chip and how well they can be repaired. Absolute black granite is the hardest colour of granite to repair and any mottled granites are easier to repair. The edges of granite worktops are particularly susceptable to chipping if they are subject to an impact.
So in conclusion granite worktops will scratch if they are subject to abrasive materials, these can be repaired however is they are cared for properly they will last a lifetime. Quartz worktops are less prone to scratching than granite and are generally harder to chip again these worktops are not indestuctable either.
