An outstanding, truly fine Brandberg amethyst on its own merits, but also with a very large and visible bubble right in the middle! You can quite clearly see the oval shape of it, front and center, above the yellow arrow. In the right photo, lower row, you can see the oval now moved to the other side avoer a diagonal phantom crystal in the middle, sliding right over the top. It is one of the more dramatic bubble inclusions I have seen, but ALSO present in a fine amaethyst of top quality glassiness and luster. Together, a superb piece!
