The name ‘Ratnapura’ is a Sanskrit word meaning “city of gems”, from the Sanskrit words pura (town) and ratna (gemstone). Over 2000 years ago, when the first Buddhist monks arrived here from the north eastern provinces of India namely Bodh-Gaya, Varanasi and Pataliputra, they not only brought with them the Buddhist religion, but since their teachings were mainly in Sanskrit and Pali they also influenced the local language. It is the centre of a long-established industry of precious stone mining including rubies, sapphires, and other gems. Apart from gem mining, the city is known for the production of rice and fruit. Large plantations of tea and rubber surround the city. Tea grown in this region is called low-country tea.
