Ratnapura Gem Mining Sites

June 14, 2026 claymatics.web@gmail.com Ratnapura

Overview

Ratnapura — whose name literally means “City of Gems” in Sinhala — sits at the heart of one of the world’s most productive alluvial gem-mining landscapes, where the ancient riverbeds and floodplains of the Kalu Ganga and its tributaries have been depositing sapphires, rubies, alexandrite, cat’s eye, and dozens of other precious and semi-precious stones for millions of years. The traditional gem mining method — a shallow pit (called an illama) dug through overburden into the gem-bearing gravel (illam), with circular rattan baskets used to sieve the gravel in a bucket of water — has not changed fundamentally in centuries. Visiting an active gem mining operation near Ratnapura provides a rare window into an industry of extraordinary heritage and current commercial significance, and the possibility of seeing raw sapphires and rubies being sifted from the earth creates genuine excitement.
