Australian Pink Opal Rock Slab 33

Australian Pink Opal was discovered while prospecting around the Mookaite mine. It is opalized radiolarite that was permeated with an iron solution during formation, thus giving it the bright pink color.  The opal is strikingly beautiful when it contains swirls of other shades of pink and white. The glassy quality of opal lends itself to taking a great polish but is brittle.
