Gemological Science International’s (GSI) Colored Stone Professional (CSP) Diploma programme recently organized a hands-on educational tour to Sri Lanka’s famous Rakwana Gem Deposit, giving students an invaluable opportunity to experience the gemstone industry at its source.
The field visit was designed to offer a complete view of the gemstone journey — from mining and processing to trading. “Such experiences are vital for cultivating a comprehensive understanding of the gem industry,” said Ramit Kapur, Managing Director, GSI India.
At the Rakwana Gem Deposit in the Ratnapura District, students explored small-scale mechanized mining operations carried out on agricultural lands, where sapphires, chrysoberyl, spinel, and tourmaline are commonly found. They also observed traditional gravel washing and sorting methods used by local miners to identify gem-bearing stones.
“While classroom learning builds a strong foundation, witnessing gemstone origins firsthand adds an entirely new dimension to a student’s perspective,” remarked Meenu Vyas, Chief Global Gemologist & GSI Education Centre.
The visit also included a tour of the Karawita Mining Area, an introduction to Geuda sapphire heat treatment in Ratnapura, and stops at the gem markets of Ratnapura and Beruwala. Students further explored the Beruwala Gem Cutting Workshop to observe cutting and polishing processes that enhance the beauty and brilliance of gemstones.
Offered at GSI’s Jaipur centre, the CSP Diploma integrates intensive theoretical study with field experience, workshops, and practical training. This blend of scientific education and real-world exposure equips aspiring gemologists with both the technical proficiency and ethical awareness essential to thrive in the global gem and jewellery sector.
