Trivia[edit]

  • This material exists IRL. It is often found along Ruby in its veins. It is softer than ruby, therefore only flawless gems of this material can be used for jewellery.
  • This material is called Spinel and can be of many colours, including all the colours Ruby has.
  • Despite having formula CrAl2O3 (same as Ruby), its actual chemical formula is MgAl2O4. However, this material cannot be processed at all, so this does not matter.
