Gems are valuable for their beauty, cultural meaning, and use in jewelry and industry. They are also believed to bring luck and healing in many traditions.
Sri Lanka’s gem industry has a rich history, earning it the name Ratna-Dweepa or “Gem Island.” Historical figures like Marco Polo and Ptolemy praised its sapphires and other precious stones. Known as Serendib by ancient traders, the island was a key hub in the gem trade. Geologically ancient, with rocks dating back over 560 million years, Sri Lanka’s gem deposits are mainly found in the Highland Complex. These include sedimentary, metamorphic, and magmatic types, with metamorphic deposits making up 90%. Around 25% of the island is gem-bearing, with Ratnapura—“City of Gems”—being the main center.
