Australian Boulder Opal

Australian Boulder Opal



This is quite possibly the largest Boulder Opal specimen currently available online. The uniqueness of this Boulder Opal is the thickness of the Opal seam. Typical Boulder Opals have the colour filling minute fissures, cracks and crevaces in the Boulder Opal Ironstone. The layer of Opal in the Opal seam is estimated to be up to 2cm thick. Weighing in at 20kg and measuring 39cm x 23 cm this is truly a museum or boardroom display piece like no other!
