The collector I got this from mentioned that this piece had a nice amber swirl in it,.........but didn't expect this. I nearly thought someone had took a brown marker and put it on the piece their self. The swirl is dark amber and is all the way on the very outside of the surface it seems,.....and a lighter swirl trailing off underneath it which goes into the inner skirt. Also notice the "other" swirl to the left which is silver-grey looking and seems to consist of carbon and fine bubbles. And nice condition to.
