Nacreous pigments comprising crystalline TiO2 platelets, either supported on corresponding plate-like calcium sulfate anhydrite particles or self-supporting. The pigments are prepared by depositing amorphous TiO2 coatings on plate-like gypsum substrate particles, calcining the resulting product to convert the gypsum to the anhydrite and crystallize the TiO2 and, when an unsupported pigment is to be produced, dissolving out the anhydrite substrate. The crystalline TiO2 is produced in the form of either rutile or anatase.
