Gem mining in Sri Lanka

Since the time of the early kings, gemstone mining has been a traditional profession in Sri Lanka. Pit-head mining and tunneling are the two most popular gemstone mining techniques in Sri Lanka. Dredging river beds and surface placer mining are two more popular techniques.

Gems are formed on the earth in association with large rocks. Gems are washed away due to rock erosion on mountains. The soil of the plains at the base of the mountains is home to gems that have been buried by rain-washed earth. The layer of material containing gems and other rock fragments is called ‘Illama’.

Mining techniques used in the gemstone industry are conventional, environmentally friendly, and ethical. Miners first dig a well-liked ‘mine’ in places where they think gems are. A ‘donna’ like the tunnel is dug parallel to the ground level from the base of the mine. They do this because the demand is parallel to the ground. Gems are separated by ‘dredging’ the mixture of materials taken from the donna from the mine.
