On exhibition trm-murwillumbah
These spherical wonders are found in the silica-rich volcanic landscape of the Tweed and tell a story of the molten lava that once flowed through the area over 20 million years ago. As the lava cooled, the trapped gas and minerals produced a stunning array of colour and crystals inside the thunder eggs. This collection is currently not on display until 2024.
