14.6" Polished Brecciated Pink Opal - Western Australia

Breciatted pink opal is really a different form of mookaite, a type of opalized radiolarite. It is mined from a single prospect 1 kilometer south of the Mooka Creek deposits near Carnarvon, Western Australia. It is found as a dominant horizontal bed within zones of coloured porcellanites located beneath a surface brecciated zone of iron, silica and pink opal fragments. The pink opal often shows Liesegang banding, and microcrystalline quartz-filled vugs.
