Gemstone collector Duong Ba Dung is showcasing his collection of over 600 precious stones at a gallery space in the ancient town of Hoi An.

It's one of the biggest exhibits of gemstones in Vietnam.

He said it took 20-years to collect his precious stones, and the gallery was a popular destination for tourists in Hoi An which was recognised by UNESCO as a heritage site in 1999.

The gemstones range from raw stones, tektites, sapphires and tourmaline.

Over 400 sculptures and precious stone jewellery are also on display at the gallery.

Hoi An, located in the central coastal province of Quang Nam, is an old trading port that dates back to the 15th century. Its architecture and layout reflect the indigenous and foreign influences that melted together to produce the unique character of the town.-VNA
