Sri Lanka, an island nation long known for its wide variety of sapphire, cat’s-eye chrysoberyl, and many other gemstones, is enjoying a resurgence in its gem and jewelry industry. Situated off the southeast coast of India—directly in the path of an ancient trade route for seafaring merchants—the “Island of Jewels” is a major source of colored gemstones and a center for cutting and heat treatment.
In February 2014, GIA field gemologist Andrew Lucas and video producer Pedro Padua traveled to Sri Lanka for two weeks with an ambitious goal: to document the country’s entire gem and jewelry industry, from mud-drenched mines to glittering retail stores. This was a true mine-to-market expedition covering all aspects of the industry, including:
- Colored gemstone mining, cutting, and treatment
- Colored gemstone wholesale trading
- Jewelry design and manufacturing
- Retail and pawn
They discovered a dynamic industry that blends centuries of experience with modern methods to meet the needs of the international gem and jewelry trade. With improved access to rough from outside sources, modernization of cutting techniques, precision-quality manufacturing, and expertise in heat treatment, Sri Lanka has made substantial gains in the global sapphire market.
This expedition was made possible by tremendous support from the Sri Lankan industry, whose members provided logistical support, background information, and trade experience. They opened the doors to the island and its industry, lending decades of knowledge to provide a complete picture of the local gem and jewelry trade.
Lucas and Padua teamed up with GIA’s Dr. Tao Hsu and a pair of Sri Lankan industry leaders to produce two field reports and a G&G article based on what they found.
