Best of the best
- diamond and its polymorphs including hexagonal diamond aka lonsdaleite
- moissanite - SiC - high heat resistance
- stishovite and seifertite - metastable ultrahard and dense SiO2 polymorphs
Simple rutile structure & hard
- rutile TiO2
- stishovite - metastable SiO2 polymorph - rutile structure & very hard and dense
- Neo-polymorphs of the above
Simple salt structures
- Periclase
- Some transition metal monoxides
Con: low crystal structure symmetry
- leukosapphire - very hard
- quartz
Con: Rather soft materials
- Calcite and aragonite
