Get the Hyrsl & Neidemayr book on inclusions in quartz. They list just about everything. I'm no expert on this, though I have the book. My guesstimation is this may be man-made - even if pure Si02. As it is polished, one can not see any faces to prove it is natural quartz. The Chinese have been making a lot of strange, if attractive, man-made 'minerals' even with bubbles and fluid inclusions. On the other hand perhaps it is natural and just very unusual. Maybe you can interest some university to do some sophisticated tests. Ramen spectrography is the hot new thing - but there are plenty of other tests that use equipment few of us have in our homes or garages. Just looked in their book and they list no Co compounds - although there are a lot of blue inclusions. And if you have a really good geological library at hand the ultimate book is the three volume 1500 page Photoatlas of Inclusions in Gemstones published by GIA!

Thanks a lot!
I'll see if I can find those books in a library.

Hi Peter,
I haven't found the books yet, but I have found blue fluid inclusions in another specimen and this one sure looks natural.
