Freeform 11.1ct untreated N2 dark Lightning Ridge black opal loose blue purple

A natural solid opal from Lightning Ridge, Australia.
 
The opal is a 11.1ct opal and the opal is freeform cabochon faceted and is one my my biggest opals, the colour is so so blue when the opal lights up however only parts of it lightup at any one time as it is a chaff patchwork type pattern that at different angles an electric blue colour with a hint of mystical purple shows.
 
The opal is hard to measure as it is freeform at its longest is around 19mmx15mmX6mm.
 
The opal is N2 colour darkness, the colours are mostly blue colours of electric blue colour tones with some purple colours too.
 
The opal has no cracks, neither surface cracks or any cracks on the inside, there are however natural lines that formed as the silica/opal formed.
 
The opal is guaranteed to be a solid opal, not a doublet or a triplet opal and not a treated opal and if the buyer gets IGI or GIA for this they return the gem to me if there are any gem treatments whatsoever.
