The bodies of these boxes were made of gold, silver, rose gold and wood and there were silver and gold-plated boxes. They were made in two styles, simple and decorative, with embossed figures of swans. The body of the box on display is gold-plated. Then the box was heated; the mercury vaporized and a gold covering remained on the embossed design of swans in a lotus pond. The swan represents Queen Sri Bajarindra, the prince’s mother.
