To extend the scope of services to its members, a testing laboratory was established in 1993 in the same premises under the name of Hong Kong Jade & Stone Laboratory, with an aim to provide impartial and objective testing of jade and gemstone by qualified gemologists with full certification. To cope with the increasing demand from jade traders on the Kowloon side, a second laboratory of HKJJA started to go into business in 2001 on Canton Road, which is seen by most in the trade to be a famous jade bazaar or trading hub of jadeware.
