Australian Opal Loose Gemstone

This natural Australian opal was purchased in Australia. Sadly, I never had it set. The stone exhibits the characteristic "play of color" associated with opals, displaying flashes of blue, green, and potentially other colors as light interacts with its internal structure. Lovely reflection, depth, and glow to the stone. Would be nice in a ring or necklace setting. The back of stone is natural, depicting its authentication. Please see the measurements for size.
