What is the National Gem and Jewellery Authority?

The National Gem and Jewellery Authority (NGJA) is the official body of the Sri Lankan government, put in place to oversee mining, valuation, and gemstone export. It is meant to protect the trade itself and also the consumers, because without that structure, things can get messy. The NGJA issues trading licences, runs testing laboratories, and checks that quality standards are actually followed.

For tourists, the NGJA works like a main safeguard against fraud, even when they are just visiting for a short time. In Colombo, they provide an independent gem testing service, so a buyer can confirm what they have in hand for a small fee. Also, if a shop shows an official NGJA licence, it is legally required to follow state regulations. That means there is a dependable path for dispute resolution later, if the stone is discovered to be synthetic, or if its details were misrepresented in the first place.
