Description: Mookaite, also known as Mookaite Jasper is a silicified porcellanite mineral, essentially fossilized sea floor sediment. Mookaite is comprised of chert, opalite, chalcedony, or combinations of all three. Mookaite is found in Western Australia. A similar Moroccan stone is also sold under the Mookaite name. The different colours within are various settlements of fine grain silica that hardened over time. It is one of the few clean yellow stones available for lapidary use. Traditionally, mookaite has been regarded as a nurturing stone associated with courage.
