  • Pro: Titanium is common in earths crust (and in space)
  • Pro: Hardness is high
  • Pro: Crystal structure is simple
  • Con? unit cell is a bit big

Overall a good large scale structural base material for gemstone metamaterial technology.

  • Formula: TiO2
  • Hardness Mohs 8.5
  • Crystal system: Trigonal (the same as sapphire but different unit cell)
  • Density ~4.53g/ccm
  • Refractive index: ?? – likely quite high

Misc trivia:
Titanium is in a unusual trivalent form here
(as in grossmanite a titanium chain silicate).
