AI-assisted summary

Description from the seller

Large specimen of natural, untreated Australian boulder opal.
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!
