Corundum (Ruby & Sapphire)

Corundum is a crystalline form of aluminum oxide with a hardness of 9, forming in the hexagonal crystal system. Its two most valued varieties are *Ruby* (red) and *Sapphire* (blue and other colors), both valued as gemstones.

Ruby symbolizes vitality, passion, and protection, while Sapphire is associated with wisdom, truth, and mental clarity. Sapphires occur in many colors due to trace elements, with rare varieties such as the orange-pink *Padparadscha*.

Notable Corundum sources include Myanmar, Sri Lanka, Cambodia, Tanzania, India, Pakistan, and Australia, with historic but now scarce deposits from Kashmir, India.

Energetically, Corundum stones are linked to strength, focus, insight, and the activation of higher awareness and inner power.
