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 titanium gemstones including: TiN TiP TiC TiSi2 TiB2 TiO2 Ti2O3
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 MgO
- some transition metal monoxides (TiO, FeO, NiO, ..)
Con: low crystal structure symmetry
- leukosapphire - very hard
- quartz - and other low density polymorphs of SiO2
Con: Rather soft materials
- calcite and aragonite
