Physical properties
Hardness of 6.5-7 on the Mohs scale, vibrant multicolored patterns of red, yellow, purple, and brown, vitreous to dull luster, microcrystalline quartz structure.
Formation & geological history
Formed from the skeletons of radiolaria in shallow marine environments in Western Australia during the Cretaceous period.
Uses & applications
Used primarily for ornamental carvings, polished display stones, and distinctive jewelry pieces.
Geological facts
Mookaite is found exclusively along Lightning Creek near Mooka Station in the Kennedy Ranges of Western Australia.
