73rd Bangkok Gems Fair Sees Lab-Grown and Colored Gems Outshine Natural Diamonds

Visitor interest and buying power at the 73rd Bangkok Gems & Jewelry Fair shifted decisively toward coloured gemstones, lab-grown diamonds and contemporary materials, according to opening‑days coverage of the show held Feb 22–26, 2026 in Bangkok. The fair was organized by the Department of International Trade Promotion (DITP) with the Gem and Jewelry Institute of Thailand (GIT) as co-organizer, and Gem Spectrum's press material set a trade-value target of 150 million USD for the edition.

Organizers announced preparations at a press conference on January 22, 2026, and Gem Spectrum published a fact sheet positioning the event as a global trade platform to support Thai entrepreneurs and align with the country’s National Strategic Vision. The fact sheet named DITP and GIT explicitly and included a photographic preview; one image caption reads, “Mr. Boonyarit Kalayanamit, Chairman of the Board of the Gem and Jewelry Institute of Thailand (GIT), the co-organizer.

Gem Spectrum’s product-category listing for the fair underlined the breadth of goods on show, naming Gemstones, Fine Jewelry, Silver Jewelry, Gold Jewelry, Diamonds, Pearls, Lab-Grown Diamond, Costume Jewelry, Fashion Jewelry, Jewelry Part, Synthetic Stones, Equipment & Tools, Machinery, Display & Packaging, and Institute Thai and international. That catalogued mix made space for both traditional natural stones and a substantial synthetic and lab-grown presence on the trade floor.

The opening-days observation captured the tone of buyer activity precisely: “visitor interest and buying power are increasingly concentrated in coloured gemstones, lab-grown diamonds and contemporary materials.” National News Bureau of Thailand posted on Facebook that “Thailand’s gems and jewelry industry is set to shine again as the 73rd Bangkok Gems and Jewelry Fair opens in the capital, drawing strong international participation and upbeat trade projections.” The NNT Facebook excerpt in the circulated materials showed engagement markers including 6K views in the provided screenshot.

Practical consumer context ran alongside trade activity. A separate consumer guide from BcClark included explicit maintenance instructions for natural diamond owners: soak diamond jewelry in solution for 20 to 30 minutes, gently scrub with a soft toothbrush focusing on the back of the diamond and crevices, rinse under warm water, pat dry with a clean paper towel and allow the piece to air dry completely before storing. BcClark also details that jewelers can clean hard-to-reach areas, check for loose prongs or weak settings and detect signs of wear during checkups, and notes BC Clark cleaners are sold at store locations.

Gem Spectrum’s preview carried multiple photo credits reading “Preview of jewelry in the 73rd Bangkok Gems and Jewelry Fair. Photo courtesy of the Bangkok Gems & Jewelry Fair,” while the fact-sheet structure shows sections titled 6. Format and 8. Exhibitors that were referenced but not included in the excerpt. Organizers set the 150 million USD target publicly; with Feb 26 concluded, final trade figures and exhibitor counts will determine whether the evident tilt toward lab-grown and coloured gems translates into the anticipated orders and long-term shifts in Asia’s trade patterns.
