The country where diamonds were discovered earlier was India. More than 2,800 years ago, the Krishna River, Penna River and its branches in the Kingdom of Andhra Gorconda (now India) were mined on a large scale for diamonds. Before the mid-18th century, Golconda was the largest diamond supplier in the world.

Diamond, the original name comes from the Greek "adams", that is, "invincible" meaning.

In the mid-17th century, Brazil discovered diamond placer deposits in Piaui, Minas Gerais and other places, and since then Brazil has replaced India as the main source of diamond land in the world.

In 1866, diamond was discovered in South Africa, which was a historic shift in the history of global diamond prospecting. The diamond was found by Daniel Jacobs' daughter while playing by the Orange river near Hopetown, west of Kimberley City in Cape Province. In 1869, the Star of South Africa was discovered in South Africa. Since then, the Union of South Africa has set off the climax of the search for diamond, and has found a number of large-scale, high-quality diamond placers in the Orange River and its tributary Waal River Road, after a few years, South Africa has found a number of primary diamond deposits. Subsequently, the Soviet Union, Australia, Zaire, China and other countries have also discovered diamond.

Due to the lack of natural diamonds, humans began to try synthetic diamond. H.Moissan, a French chemist, realized that graphite in nature was converted into diamond under high temperature and pressure, and designed an experiment that imitated the natural process of converting graphite into diamond. He dissolved layers of graphite into newly melted steel, and attempted to use the strong pressure created when the liquid steel was quickly cooled, and when the iron became solid, the graphite quickly turned into diamond. In 1880, British scientist J.B. Hannay reported that he made gold by sealing a mixture of hydrocarbons, bone oil, and lithium in a wrought iron tube and heating it until it was hot.
