Bangkok Gems and Jewelry Fair Data.

Stone, source, and craft

The official English name is Bangkok Gems and Jewelry Fair. The fair also uses the shorter name Bangkok Gems. It is a trade event in Bangkok, not a permanent gem market. Its scope is much wider than the city. It brings Thai firms from many provinces together with overseas buyers, sellers, and trade groups.

The fair is now run by the Department of International Trade Promotion, or DITP, and the Gem and Jewelry Institute of Thailand, or GIT. DITP sits under Thailand's Ministry of Commerce. The fair's own history says the first Bangkok Gems event took place in 1983. It moved to a twice-yearly cycle in 1991. The modern fair is linked with the February and September trade calendar.

That history makes the fair part of Thailand's export system. It is not only a display of finished rings and necklaces. Its product groups cover loose colored stones, diamonds, pearls, gold and silver jewellery, fine jewellery, fashion jewellery, parts, precious metals, tools, machines, packaging, and related services. The mix shows how many kinds of work sit behind the Thai gem trade.

Thailand's role also goes far beyond mining. A large share of rough stones used in Thai trade now comes from other countries. Thai strength rests on skills built over many years. These include cutting, heat treatment, sorting, design, jewellery making, lab work, and trade links. Bangkok Gems puts many of those skills in one trade setting.

Trade, treatment, and testing

The fair has changed with the industry. DITP ran the first event in 1983. By the ninth event in 1991, it was held twice a year. The 66th event in 2021 used a virtual format during the pandemic. In 2022, at the 67th event, GIT became a co-organizer. This gives the fair a clear line from state trade promotion to a joint trade and gem-science role.

GIT's role adds more than a name to the event. Official fair reports describe gem testing, talks, technical sessions, and design shows. A report on the 70th fair described GIT tests on site as well as talks and programs for Thai firms. This gives the fair a lab and knowledge role beside its sales role.

Colored stones are a strong part of the fair's identity. GIT's final report for the 73rd fair in February 2026 said colored stones were the most active product group. Silver jewellery, fine jewellery, diamonds, and machines or tools followed. The 72nd fair also put colored stones first. These are dated results, not fixed market shares. Still, they show the close tie between Bangkok Gems and Thailand's long role in the colored-stone trade.

The fair also gives space to small Thai firms and new makers. Its New Faces program features young or growing designers and jewellers. Recent groups have come from Bangkok and from provinces such as Chanthaburi, Chiang Mai, Chiang Rai, Tak, Nan, Sukhothai, Pichit, Phitsanulok, Uttaradit, and Udon Thani. The list changes from fair to fair. The stable point is that Bangkok Gems acts as a national stage for Thai regional craft and small firms.

Design has its own place at the fair. The Jewellers program has shown new Thai work and young talent. The 73rd fair used the theme Orbit of Illumined. The 72nd fair had Gilded Souls: The Ethos of Thai Craftsmanship. The 70th fair had Spirit of Jewelry Making. These shows do not prove that there is one single Thai jewellery style. They do show that the fair treats craft and design as part of the trade.
