6.45ct untreated Australian solid opal blue and purple fire

From Treasurentreats / Prelovedbargains.
 
A natural solid opal.
 
A solid opal is not a doublet or triplet opal, doublet and triplet opals are partly natural but partly not, they are opal with a plastic or crystal dome on the front. 
A solid opal is opal from the Earth, without any doublet or triplet opal treatments, justfaceted and polished organic gem.
 
This opal shows gorgeous blue and purple colours, two colours and though the images show lots of blue, there is lots of purple too!
 
The piece is large, it is a big gem, satisfying but not too big, 15.74mmX12.58mmX5.24mm.
 
This opal is from Australia, it is a Lightning Ridge opal.
 
As stated, this is a natural gem, without any gem treatments, if any gem treatments are found the buyer can return the gem to me for a refund.
