Does gypsum scratch flourite?
No. Gypsum has a hardness on the Mohs scale of 2. Topaz has a hardness on the Mohs scale of 8. This means that topaz ranks much harder than gypsum and that gypsum cannot scratch topaz. Please do not refer to these numbers as absolute hardness. This does not mean that topaz is 4 times as hard as gypsum since they are ranked 8 and 2. The Mohs scale only designates a hardness scale of 1 through 10 so that geologists and mineralogists in the field have a quick way of determining a mineral's identity or eliminating possible options of what the mineral may be.
