Hi~
Recently I got this phantom quartz with blue inclusions (pic1).Look like the inclusions are dyed into the blue color.But I also found parts of the inclusions are well wrapped inside the quartz, there's no way for the color dye to get in. Later, I got another quartz of this kind(pic2).With this quartz , isolated chambers with blue fluid and bubbles inside can be found under microscope(pic3).I know there are some quartzs from Brazil that have blue fluid inclusions inside. Could this blue fluid be the "color dye " that dyed the inclusions of these phantom quartzs?

Isolated chambers with blue fluid and bubbles suggest that they can not be dyed by man.
However,the blue inclusions turn red under Chelsea filter and have a visible absorption spectrum quite similar to cobalt glass's.
Does cobalt fluid really exist in nature? Or ,it's something else?

Found blue fluid inclusions in another specimen.
Now I'm quite sure of the natural dyeing theory.

There is quarze with vivid blue liquid inclusions...

I tried to get such a piece but was finally too expensive.

Very cool material! Where is it from? Are you sure it isn't just a very nice example of the Brazilian material?

Maybe you contact Luciana Barbosa.

http://www.lucianabarbosa.com

She offers Dumortierite in quarze and offered the large quarze with blue fluid inclusions a few month ago...

This item showed bubbles too...

Thanks,Marlow
Now I'm sure that the blue phantom quartz and the blue fluid quartz are the same type.
Just no one has ever connected them together before.

Interesting are the black or dark coloured needles in the rough item too.

Were do you live? Maybe there is a larger show around.

Or contact GIA...

I live in China and I bought them online.
In order to study them, I bought as many as I can until there is no more left online.
Eventually I got 5 specimens in total and they all have these hairlike inclusions inside.
