Mechanized gem mining in Sri Lanka typically involves using machinery such as excavators and bulldozers to extract gem-bearing material, especially in larger-scale operations in gemstone-rich areas like Ratnapura — the heart of Sri Lankan sapphire mining. This method is faster and more productive than traditional mining, helping uncover Ceylon sapphire deposits that are located deeper underground.

However, mechanized mining can cause significant environmental impact and is therefore strictly regulated. The Sri Lankan government enforces mining licenses, environmental protection guidelines, and restricted zones to preserve the natural ecosystem and ensure that natural Sri Lankan sapphires are sourced responsibly and legally.
