The Diamond Federation of Hong Kong, China (DFHK) is a non-profit organization aims to protect the integrity of diamond and consumer’s interest by standardizing business practice. It is a joined force of two long established associations in Hong Kong, namely the Diamond Importers Association (1959) and the Hong Kong Diamond Bourse (1985).

Since January 2000, DFHK has undertaken their missions in maintaining Hong Kong’s reputation as the diamond centre in Asia and in promoting quality services and consumer rights. Consequently, the Integrity Pledge Scheme was launched to ensure an ethical and professional image of our members. Under the self regulatory schemes for the diamond industry, members would mark on the sales invoice a true description of the diamond sold over 0.30 carat. Consumers therefore can shop with confidence and enjoyment.

The emergence of the Asia Pacific region as an important market for diamonds prompted diamond dealers in Hong Kong to establish a bourse that would place them on an international footing. Operations were officially inaugurated in March 1985 and by June 1987 the HKDB became the 20th member of the World Federation of Diamond Bourses (WFDB).

The Diamond Importers Association (DIA), a nonprofit organization founded in 1959, had played an important role in raising Hong Kong’s position as the Diamond center in Asia. Its aims were to raise the local standard of diamond trading, to fortify the reputation of its members and to protect consumers’ rights, such that the consumers can buy diamonds in Hong Kong with confidence.

For the protection of the consumers, DIA offered complementary "Introduction Card Kit”, from 1970’s until the merger with DFHK, to visitors and local residents. DIA was behind the consumer in every purchase, giving the pledge of Confidence. The "DIA” Decal displayed in a jewelry store, symbolizes reliability, confidence and professionalism.
