Some may call this pattern a 'cat's eye pattern' others may call it a 'rolling flash pattern', depends on how you see it ... we call it 'gorgeous' because this black opal loose is just GORGEOUS however you see it !! Nice flashy color with blue & violet, perfect dark body, shape is also perfect, exceptionally great value and its beauty can never be repeated. Another lovely piece of black opal found at Lightning Ridge, NSW, Australia.
