    Long before Ben Franklin, Indians knew about the hardness of diamond.Sanskrit texts from India dating to 500 BC refer to diamond, indicating a clear knowledge of this material. In fact the famous Diamond Sutra of Gautama Buddha uses this term in an allegorical sense to indicate that these chants can cut through illusions, just as diamond cuts through other substances. The Diamond Sutra (although a more accurate translation of the Sanskrit title ” Vajracchedikā-prajñāpāramitā-sūtra ” will be the Vajra Cutter Sutra) is a short Mahayana sutra of the Perfection of Wisdom genre, which teaches the practice of the avoidance of abiding in extremes of mental attachment. A copy of the Diamond Sutra, found among the Dunhuang manuscripts in the early 20th century, is, in the words of the British Library, “the earliest complete survival of a dated printed book.”
