Mookaite is a stone I have worked with quite a bit. I really love cutting this stone because of the possibilities. The shades and patterns can vary so much, and sometimes the patterns create pretty scenes or eyes.
Mookaite is also known as Mookite, Mookalite, Mooka Jasper, or Mookarite. It is found in Western Australia. The Aboriginal word "mooka" means "running waters". It is made up of chert, opalite, and chalcedony.
