Large mookaite sphere, a particularly attractive polished mineral weighing in at just over one kilo.
Mookaite is a variety of the mineral jasper that's sometimes also known as Australian Jasper or Mook Jasper. Originally given this name by locals simply for identification purposes, the name stuck and is now widely used and recognised even though it has never been officially registered. It was named after Mooka Creek which is the location in Western Australia where the stone is found.
Exceptionally colourful and taking on a high polish, Mookaite often displays hues of red, orange, blue, green and yellow. It's relatively hard and grades 6½ to 7 on Mohs scale of mineral hardness which makes it ideal as a lapidary material. Mookaite is often crafted as a cabochon for use in ladies jewellery, it's also polished into beads and stones may also be tumbled.
