Gemstones Mining in Sri Lanka
Sri Lanka is famous for its great variety and abundance of extremely high quality
gemstones. Significant gem fields had been known since historic times. These fields are
largely confined to alluvial soils deposited by the larger rivers draining the central,
southern and western parts of the country.
The methods used have dominated for nearly 2,500 years and are simple, small-scale and
worked on a system of cooperative sharing of the profits from the activity. In pitting, shafts
are made to reach where deeper levels of gem-bearing gravel exist. Tunnels, which rarely
exceed 10-12 feet, are made to collect the gravel. Walls are supported with timber species
that resist rot and fern is used for panelling to protect against water seepage into the tunnel.
Pits are generally confined to marshy terrain and paddy lands. Gems are also mined from
riverbed material by a method of dredging. Generally 4-10 people work each pit. Flooding
is the main hazard in pit mining and the workers of the present day generally use water
pumps to dewater.
