Demantoid garnet in real life.

  • Demantoid, also called demantoid garnet and demantoid andradite, is a member of the garnet group.
    • It has a chemical composition of Ca3Fe23+(SiO4)3, a hardness of 6½ - 7, and a isometric crystal structure.
  • Demantoid is the green variety of andradites, a calcium iron garnet.
  • They typically form when argillaceous limestone is altered into marble by contact metamorphism.
  • Demantoid gets its color from chromium and ferric iron.
  • It's said to be one of the rarest and most valuable of all garnets.
  • Demantoid was discovered in  the Ural Mountains of Russia, somewhere during the 1850s.
  • Russian demantoids are known for their "horsetail" inclusions of byssolite or chrysotile asbestos.
  • Like all garnets, demantoid is the birthstone for January.
    • Being a type of garnet also means it's a state gemstone for New York.
  • Demantoid's name comes from archaic German word "Demant" which means "diamond-like".
  • Metaphysically, demantoid is a pledge stone that removes obstacles in the way of love. It's said to help with insecurities that strain a relationship.
    • Demantoid is also said to help loneliness and isolation.
    • Garnets in general represent self-confidence, beauty, love, determination, good health, bravery, and strength.
