Islam

  • Sapphire appears in Islam.

    The Qur’an (55:58) likens the companions of the Garden to rubies and coral — yaqūt speech that licenses this corundum/sapphire seat in Islamic gem speech. Islamic yaqūt attestation in that revelation, not glass as the Light-Verse already walked and not a jewelry dump alone.

    from M.A.S. Abdel Haleem (translation) · The Qur’an, 2004 (this translation); Arabic text 7th century CE
