The ancient Indians revered diamonds as a gift and tool of the gods. Carrying a diamond was seen as a good luck charm and a protection from threats like poisonous snakes, fire, thieves, or evil spirits.
In the Indian ancient scriptures, diamonds were divided into the same four caste groups, according to the colour: “the diamond has four colours, according to its caste. The diamond that has the velvety lustre of the mother-of-pearl, the rock crystal, the moonstone is a Brahmin. The one that is slightly red, monkey brown, beautiful and pure is called Kshatriya. The Vaishya is a lustrous, pale yellow. The Shudra shines like a polished sword: the experts have classified it into the fourth caste on account of its shine.”
