Ratnapura – The gem city

This gem mining centre of Sri Lanka is a major crossroad between the southern plains and the hill country to the east. Ratnapura, home to many prominent gem dealers in Sri Lanka, is a bustling market city servicing most surrounding towns. It is known as the City of Gems and has been known as such throughout the history, even referred to in ancient texts.

Gem mining is widespread throughout this region. A unique feature of gemstone distribution in Sri Lanka is that a variety of different stones are invariably found together at one site. The region is infamous for the following gemstones: various spinels, aquamarines, tourmalines, topaz, garnets, amethyst, cat’s eyes, zircons and moonstones.
