Yep!   The Victorians thought that they were 'bad luck' but if they are I've avoided it so far :)   I picked this one up in Bangkok because it reminded me of the Northern Lights I used to see when winter drilling.   As with this opal, the northern lights way up north are curtains of colour that would shot overhead (sometimes all the way to the southern horizon) and seem to drip down in multiple veils of different coloured lights.  Just one of the better memories from being in a tent camp in January where -40 degree nights were the norm.  Other than that its distinctive.   Nothing else to the story.
