Gem City Ratnapura 2026 runs 31 August to 2 September in Sri Lanka's gem district. The 2025 edition was held in Pelmadulla; NGJA will confirm the 2026 venue as show week approaches. The event is aimed at miners, dealers, cutters, jewellery manufacturers, and international buyers who want direct access to Ceylon material before the September fair circuit in East Asia. If you are flying in, treat the three days as concentrated sourcing, not a casual market stroll.
What changed in 2026 matters before you book a ticket. January's weight-based import tax revision was designed to make rough entry more predictable after two years of stalled parcels, though trade press reported that import volumes were still recovering slowly into mid-year. In late July, Cabinet approved folding the Gem and Jewellery Research and Training Institute into the NGJA, mostly an administrative merge of training and regulation under one roof. That is housekeeping for dealers and cutters, not cheaper stones. Read our news brief on what the merger means for the trade.
Before you fly, sort logistics early. Most wholesale visitors use a business or tourist visa arranged through Sri Lankan missions abroad. Carry USD or EUR for larger deals; small cash purchases still happen at booths, but wire transfers through licensed exporters are normal for serious parcels. Decide which lab papers you will accept: NGJA government reports for export baseline, plus private Colombo or Beruwala labs (GIC, GGTL, PGTL, TGL, AGTL) for advanced testing. Swiss and US lab names (SSEF, Gübelin, GIA) are not issued on the show floor; plan time in Colombo if you need them.
At the fair, separate the NGJA information desk from dealer booths. Government staff can explain licensing and export procedure; they do not vouch for every stone on display. A card that says Ceylon or Sri Lanka means origin marketing unless a lab report on the same tray states origin with a number you can trace. Ask to see the stone in daylight or neutral LED, not only under strong fair spotlights that flatten colour.
Certs and video follow the same rules as our reading-a-listing and heated-vs-unheated guides. Heat treatment is standard on much commercial blue sapphire and must be disclosed. Unheated claims need lab support, not dealer assurance alone. Pause on face-up colour, windowing, and silk. If a seller refuses video or a neutral-light re-check, walk away regardless of price.
Fair buying vs online buying is a trade-off, not a moral test. At Gem City you can compare many stones quickly and build relationships with cutters who may not list online. Online, you get permanent video, written treatment lines, and time to inquire without travel cost. We list filmed stones year-round and run live auctions between fairs; if you cannot reach Ratnapura, use our collection and auction pages with the same verification discipline you would use at a booth.
Practical checklist for show week: confirm export licence path before you pay; photograph the stone next to any invoice; match cert number to the stone where possible; agree who pays for re-cutting or repolishing if needed; and budget landed cost if you are exporting (duties at home are yours). After the fair, serious suppliers often continue deals by WhatsApp or email. Keep copies of every document.
Gem City concentrates supply and attention for fair week. Whether you buy at the exhibition or from a filmed listing afterward, the standard is the same: honest media, clear treatment, and paperwork that matches the stone in your hand.
