Mined from: Mooka Station, Carnarvon Shire, Western Australia, Australia 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 which is found only in Western Australia. 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.

Mookaite helps us with decision making, especially when we are having a difficult time.
