"its2in0the1numbers1 If nobody gets the answer right I'll reveal what it is in the next video. But just a hint. It's a gem from the USA and it's in the feldspar family."
It's got to be labradorite/bytownite/whatever plagioclase group member from Oregon, Idaho, Texas or whichever more obscure locale.

Im learning a lot about feldspar today. I've got to watch out for it, this stuff is weird. Never knew labradorite and sunstone can be transparent and free of inclusions and phenomena. thanks for enlightening me.

Technically if there isn't any phenomenon it isn't really sunstone (since sunstone has to have schiller phenomenon by definition). It gets used on clear Oregon material anyway, mostly I think because Oregonians want to be able to sell it.
Either way, it's surprisingly nice stuff.
