An unusually hard lead mineral is plattnerite (PbO2). Its crystal structure is the rutile structure. Just like it is the case with the corresponding minerals of leads group members (carbon excluded):
- Plattnerite PbO2 (Mohs 5.5; ~9.63g/ccm)
- Cassierite SnO2 (Mohs 6-7; ~7.1g/ccm)
- Argutite GeO2 (Mohs 6-7; ~6.28g/ccm)
- Stishovite SiO2 (Mohs 9-9.5; 4.287g/ccm)
