Mookaite Jasper, or Mookaite (Chert), carries a predominantly reddish-rose color, marbled or striped with bands of yellow, cream, tan, white or brown; named for the Mooka Creek area in Western Australia where it is mined. Mookaite is an Aboriginal Mother Earth stone known for its healing and connection with the positive energy currents of the Earth. It increases life force in the physical body, and promotes an ageless spirit willing to accept change and seek new experiences. It awakens the energy of one’s own instinct, and is an excellent stone for pregnant parents to communicate with their unborn child
