Ceylon sapphire is not a museum piece. Alluvial gravels around Ratnapura, Pelmadulla, Elahera, and other districts still yield corundum from small-scale operations. Quality varies from included Geuda to eye-clean faceting rough.
Weekly gem markets and dealer networks move new crystal into cutting workshops. Laboratories issue origin reports on contemporary stones, not only on legacy goods. That continuous pipeline is the access advantage over Kashmir, Burma spinel-tier scarcity, or one-off Montana finds.
Production scale is modest compared with mechanized mining countries, which helps the origin story but limits volume of top unheated blue. Most rough is heated at some stage. Fine unheated remains a small fraction.
For a mine-to-market shop, active production means relationships with miners and cutters refresh inventory. Buyers get stones mined and cut recently, with media captured under known lighting rather than estate mystery.
