![]() Polychrome Jasper from Madagascar is very similar in appearance to Mookaite, but Mookaite is only found in Australia and its colours tend to be punchier and more vivid. ![]() Jaspers are seldom found sporting a single colour and Mookaite is no exception. Mookaite is incredibly vibrant in colour, and displays a range of vivid scarlets, brick reds, mustard yellows, and deep maroons in swirling patterns. Gemstone Mookaite sourced from this formation often contains opaline and chalcedonic elements and tends to form in nodules, from which it is mined, cut, and polished into colourful gems.Consequently, this type of rock is called Radiolarite after the creatures it is formed from, and more specifically rocks from which Mookaite is mined are called Windalia Radiolarite after the Australian area the geological formation is found.The vibrant colours and patterns of Mookaite are caused by these other minerals seeping in from groundwater, such as manganese and iron.As the sea levels receded and groundwater rich in silica and other minerals seeped into the sediment, these fossilised remains were entombed in ever deeper layers of sedimentary rock, forming Mookaite.Their hard silica shells and mineral-rich skeletons decomposed on the sea bed, forming sediment.Over a hundred million years ago in the Lower Cretaceous Period, microscopic sea creatures called Radiolarians died and sank to the bottom of the sea bed in an area of Western Australia named Mooka Creek.Mookaite is built from fossilised remains of microscopic aquatic creatures, and some rare pieces can even contain trace fossils from the dinosaur era. It is often referred to as a form of Chalcedony, but geologists argue that technically it is a silicified (silicate-rich) form of Porcelanite rock. Generally speaking, it is a silicate mineral in the same vein as Quartz. The mineral composition of Mookaite is referred to in a wide variety of terms such as Chalcedony and Chert.
