India was the first country to find diamonds. In India's Caucasus Mountains, there is a mineral called "Caucasian stone", which contains diamonds. As early as the 4th century BC, Indians began to dig and use diamonds. In Indian historical documents, there are also records about diamonds. For example, the Sutra of Anuttara Sancho Sanbodhi mentioned that "diamonds are a kind of jewels, whose light can illuminate the whole world".
In India, diamonds are regarded as sacred objects and are used to decorate religious ceremonies and the crown of the king. In India's aristocratic society, diamonds are also symbols of status and wealth. With the development of trade, diamonds have also been spread to other countries, such as Persia, Egypt, Rome, etc. It was not until the 18th century that diamonds were found in South Africa, becoming the largest diamond producing area in the world.
