Crystal Kingdom was established in 1974 and later expanded in 2004 to make room for more specimens that had never been on display before. This display included crystals, minerals and fossils from the local Warrumbungle Range. This was the first collection in Australia to display minerals and fossils from one local area only.
The Warrumbungle Range includes two extinct volcanoes, the Warrumbungle Volcano at 17-14 million years of age and the Garrawilla Volcanics which was active 24-200 million years ago.
This exhibit contains some of the world's rarest and most colourful zeolite crystals and rare fossils that are found nowhere else in the world.
