In early 1980s, Staff was sent to the United Kingdom again for training, this time to the Birmingham Assay Office, to learn about the system and operations of an assay office. It was necessary in order to set up and run the Singapore Assay Office.

Upon returning, the Singapore Jewellers Association, then known as the Singapore Gold and Silver Merchants Association, was approached to get support from local jewellers to send in jewellery articles for testing and hallmarking.

Soon the market open up and buyers from the Middle East began to buy jewellery in Singapore, thus requiring an independent body to test and hallmark the articles for its stated fineness before they return.

It was in 1985 that staff was once again sent to United Kingdom again for re-training, this time, to the prestigious London Assay Office.

Soon after that, the Singapore Assay Office and Singapore Jewellers Association began talks of setting up a joint promotion scheme to encourage its members to sell hallmarked articles.
