Description from the seller
Beautiful specimen of Australian boulder opal, natural and untreated, with large areas of iridescence.
Please note that the photos were taken on both dry and wet opals. Obviously, wet opal appears brighter and more colorful, highlighting the effect achieved after polishing. In Australian mining practice, rough opal is conventionally photographed wet, not to mislead buyers, but to represent the stone's potential. For this reason, we encourage you to carefully evaluate the photographs before bidding. Thank you for your attention and happy bidding!
