I would be most grateful for any opinions on these inclusions in a flame fusion spinel. :)

Since none of the experts have said what they are I'll
offer my (uneducated) guess at - explosive gaseous bubbles ?

Thank you very much for your reply!
I appreciate any help or guess :wink: perhaps you have a picture? (fingers crossed)

I have searched for inclusions pics of flame fusion spinel, but I can't find much at all. Most of them are of flame fusion corundum and doesn't resemble what I see.

Actually - following one of the links Barbra posted recently I noticed some inclusions
in photo's similar to yours - particularly the straight ones.
In this case the inclusions were said to be liquid.

given the use use of hydro/oxygen in the manufacturing process I guess
it isn't beyond the possibility that you have water inclusions - assuming
the stone is in fact flame-fusion

Still just a guess though. After that I'd be asking stephen about his current
price on a raman device... :)

Ramans are amazing tools, but you'd need a confocal raman microscope to identify inclusions which tend to be in a higher price bracket.
