Ratnapura, literally “city of gems,” sits where river gravels from the central highlands deposit gem-bearing sediments. The region’s geology—metamorphic belts rich in corundum, spinel and chrysoberyl—feeds a long history of mining, trade and lapidary craft dating back centuries and tied to local Sinhalese culture and colonial markets.
This experience pairs a market walk with visits to artisan workshops where cutters heat-treat, cleave and polish stones. You’ll see the practical techniques used to read clarity, cut to weight and test color enhancement; the guide will explain common treatments and what to watch for when buying.
Practical notes: the tour runs about 2.5 hours with periods of standing and close inspection. Wear closed-toe shoes for workshop floors, bring small-denomination cash for purchases, and leave large jewelry in a safe. Mornings are cooler and quieter; ask your guide about certification if you’re buying a higher-value gem. The visit is wheelchair accessible and suitable for most visitors, and it’s an efficient, revealing way to understand how miners, brokers and lapidaries turn river gravel into gemstones.
