4.6" Polished Brecciated Pink Opal - Western Australia
This is a 4.6" wide, polished slab of brecciated pink opal mined in the Gascoyne Region of Western Australia. One side is polished to a mirror like finish, making for a beautiful decorative display. Comes with an acrylic display stand.
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.
