The Hong Kong International Diamond, Gem & Pearl Show — widely abbreviated in the trade as HKJG March — is the first of three major jewellery and gemstone trade fairs held annually in Hong Kong under the umbrella of Informa Markets (formerly UBM Asia). Staged each March at the Hong Kong Convention and Exhibition Centre (HKCEC) in Wan Chai, the show draws upwards of 2,000 exhibitors and tens of thousands of trade buyers from across Asia, the Middle East, Europe, and the Americas, making it one of the most significant sourcing events on the global gem-trade calendar.

Character and Focus

Unlike the September Hong Kong Jewellery & Gem Fair, which skews toward finished jewellery, luxury brands, and retail-ready product, the March show is oriented principally toward loose stones and components: rough and cut diamonds, coloured gemstones, cultured and natural pearls, and the semi-finished findings and mountings that support the manufacturing trade. This emphasis makes it a natural destination for gem dealers, cutters, wholesalers, and jewellery manufacturers seeking to source material at an early stage of the supply chain. Coloured-stone traders in particular regard the March fair as a key moment to view new parcels from major producing regions before goods disperse through the year's subsequent trade cycle.

Position in the Hong Kong Trade Calendar

Hong Kong hosts three principal gem and jewellery trade events each year. The March show is followed by a smaller June fair and then by the flagship September Hong Kong Jewellery & Gem Fair, the latter being one of the largest jewellery trade exhibitions in the world by exhibitor count and floor space. Together, the three events reinforce Hong Kong's role as the pre-eminent gem-trading hub in Asia — a position built on the territory's free-port status, its concentration of gem-cutting and jewellery-manufacturing expertise in the Pearl River Delta region, and its deep banking and logistics infrastructure.

Significance for the Coloured-Gemstone Trade

For coloured-gemstone specialists, the March show offers an early-year opportunity to assess supply trends, pricing movements, and the emergence of new material from producing countries. Dealers from Thailand, Sri Lanka, Madagascar, East Africa, and Colombia are consistently represented, and the concentration of buyers and sellers in a single venue compresses price discovery in ways that are difficult to replicate through bilateral trading alone. Laboratory-grading reports from institutions such as the GIA, Gübelin, SSEF, and Lotus Gemology are routinely presented alongside stones, reflecting the increasing demand for certified provenance and treatment disclosure in the wholesale market.

Practical Context

The show is a trade-only event; admission requires verifiable industry credentials. Informa Markets publishes official exhibitor directories and floor plans in advance of each edition, and the organisation maintains a dedicated online portal for pre-registration and appointment scheduling. Given Hong Kong's position as a transshipment centre, many buyers combine attendance with sourcing visits to the city's established gem districts in Kowloon and on Hong Kong Island.
