11" Free-Standing, Polished, Brecciated Pink Opal - Australia
This is a 11" tall, free-standing, polished section of richly colored pink opal (opalised radiolarite). One side has been polished to a mirror like finish.
Breciatted Pink Opal is really a different form of mookaite, a type of opalized radiolarite. It is mined from a single prospect, 1 km south of the Mooka Creek deposits near Carnarvon, 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.
